A distributed three hop routing protocol to increase the
Hybrid wireless networks combining the advantages of both mobile ad-hoc networks and infrastructure wireless networks have been receiving increased attention due to their ultra-high performance. An efficient data routing protocol is important in such networks for high network capacity and scalability. However, most routing protocols for these networks simply combine the ad-hoc transmission mode with the cellular transmission mode, which inherits the drawbacks of ad-hoc transmission. This paper presents a Distributed Three-hop Routing protocol (DTR) for hybrid wireless networks. To take full advantage of the widespread base stations, DTR divides a message data stream into segments and transmits the segments in a distributed manner. It makes full spatial reuse of a system via its high speed ad-hoc interface and alleviates mobile gateway congestion via its cellular interface. Furthermore, sending segments to a number of base stations simultaneously increases throughput and makes full use of widespread base stations. In addition, DTR significantly reduces overhead due to short path lengths and the elimination of route discovery and maintenance. DTR also has a congestion control algorithm to avoid overloading base stations. Theoretical analysis and simulation results show the superiority of DTR in comparison with other routing protocols in terms of throughput capacity, scalability and mobility resilience. The results also show the effectiveness of the congestion control algorithm in balancing the load between base stations.

This document presents a new routing protocol called Distributed Three-hop Routing (DTR) for hybrid wireless networks. DTR aims to increase network capacity and scalability by taking advantage of widespread base stations. It divides message streams into segments and transmits them in a distributed three-hop manner, with at most two hops using high-speed ad-hoc interfaces and one hop using cellular interfaces. This reduces overhead, congestion, and improves reliability compared to existing protocols. Theoretical analysis and simulations show DTR achieves superior throughput, scalability, and mobility resilience over other routing protocols.A distributed three hop routing protocol to

An Even Data-Distribution Protocolfor Highly Dynamic VANET
Vehicular ad -hoc network (VANET) has a problem called high mobility and uneven distribution of vehicles which affect the performance of routing. The high mobility may changes arrangements of a network, and the uneven distribution of vehicles leads to node failures due to network partition; In an urban environment the high density of vehicle cause drastic wireless contentions. In this paper, we use the Even Data Distribution (EDD) protocol to make uneven distribution of data transmission in the vehicular ad-hoc network to even distribution. In which the high mobility of vehicles in urban areas causes loss of data due to uneven distribution in order to reduce the impact of uneven distribution we transform it into even distribution using EDD protocol.
Ensuring the Adaptive Path for the Routing in 5g Wireless Network
The document discusses routing in 5G wireless networks and proposes using cache memory rather than RAM to store routing information. This would make routing more adaptive by allowing nodes to quickly access cached routing data when paths are re-used, avoiding the need to re-broadcast routing information. It describes challenges of wireless network routing like mobility and limited resources. Existing distance-vector and link-state routing protocols are not well suited for wireless networks. The proposed system would use dynamic source routing to more efficiently establish and maintain routes while reducing overhead from periodic routing updates.

Performance Analysis of WiMAX Networks with Relay Station
IEEE 802.16 is a Broadband Wireless Access (BWA)
network and thus it is considered to be an alternative solution
to wired broadband technologies. Relay station plays a
promising role of extending the range of Base station for long
distances in WiMAX networks. Relay station is suitable to
areas with limited infrastructure such as rural, hilly and lakes,
where it is difficult to install many Base stations with each
having wired connections and it is also suitable to those phases
where obstacles made the coverage limited. The Relay station
is placed in the network connectivity from Base stations and
extends the coverage of a single Base station. In this paper the
performance analysis of WiMAX technology including Relay
station has been done. This paper also focuses on increasing
number of nodes and distance from base station to the
performance of WiMAX networks.

This document discusses an optimized link state routing protocol based on a cross-layer design for wireless mesh networks. It proposes monitoring link quality at the MAC layer and notifying the network layer of changes, allowing routes to be automatically updated without a refresh phase. This provides seamless connectivity under varying load and mobility. Traditional routing protocols either have fast but vulnerable proactive routes or add overhead with reactive routes. The proposed cross-layer design monitors links continuously and performs vertical handovers to better links to avoid these issues.
LINK-LEVEL PERFORMANCE EVALUATION OF RELAY-BASED WIMAX NETWORK
Relay technology promises appreciable network throughput and coverage enhancement which is required
for high speed wireless cellular systems to function to their optimum. This paper is focused on analysing
the link performance of a relay-based WiMAX network under varying conditions. Comparison is made
between relay and direct link communication in terms of BER (Bit Error Rate), spectral efficiency and
capacity. Effect of multipath fading and user speed on performance are investigated as well. The entire
study involves a hypothetical view as well as MATLAB simulations to predict the benefit of relay
deployment. This is aimed at solving pertinent issues such as coverage holes and cell edge problems which
are associated with traditional non-relay based cellular networks.
Quality of Service in bandwidth adapted hybrid UMTS/WLAN interworking network
Integration of Universal Mobile Telecommunications System (UMTS) and Wireless Local Area Network (WLAN) result in ubiquitous connection for end users. In the integrated network, ensuring the quality of service to users and enhancing capacity of network are prominent issues. Bandwidth adaptation technique is one of the solutions to overcome these issues. Bandwidth adaptation based on per flow and per class schemes were proposed for loosely coupled interworking network. In this paper, hybrid coupled UMTS and WLAN interworking network is analyzed with bandwidth adaptation based on per flow and per class schemes and the performances have been compared. Simulation result shows that the proposed hybrid coupled interworking network with bandwidth adaptation based on per class scheme performs better with enhanced quality of service and network capacity.
MULTI-HOP BANDWIDTH MANAGEMENT PROTOCOL FOR MOBILE AD HOC NETWORKS
An admission control scheme should play the role of a coordinator for flows in a data communication network, to provide the guarantees as the medium is shared. The nodes of a wired network can monitor the medium to know the available bandwidth at any point of time. But, in wireless ad hoc networks, a node must consume the bandwidth of neighboring nodes, during a communication. Hence, the consumption of bandwidth by a flow and the availability of resources to any wireless node strictly depend upon the neighboring nodes within its transmission range. We present a scalable and efficient admission control scheme, Multi-hop Bandwidth Management Protocol (MBMP), to support the QoS requirements
in multi-hop ad hoc networks. We simulate several options to design MBMP and compare the performances of these options through mathematical analysis and simulation results, and compare its effectiveness with the existing admission control schemes through extensive simulations.
Energy Behavior in Ad Hoc Network Minimizing the Number of Hops and Maintaini...
Wireless ad-hoc mesh network is a special kind of network, where all of the nodes move in time. The topology of the network changes as the nodes are in the proximity of each other. Ad-hoc networks are generally self-configuring no stable infrastructure takes a place. In this network, each node should help relaying packets of neighboring nodes using multi-hop routing mechanism. This mechanism is needed to reach far destination nodes to solve problem of dead communication. This multiple traffic "hops" within a wireless mesh network caused dilemma. Wireless mesh network that contain multiple hops become increasingly vulnerable to problems such as energy degradation and rapid increasing of overhead packets. This paper provides a generic routing framework that balances energy efficient broadcast schemes in Wireless (Ad-Hoc) Mesh Network and maintaining connectivity of nodes (mobile terminals). Typically, each node’s activities will consume energy, either for sending packets, receiving or preparing/processing packets. Number of hops, distance of nodes, and size of packet will determine the consumption of energy. The framework is based on the principle that additional relay nodes with appropriate energy and routing metric between source and final destination significantly reduces the energy consumption necessary to deliver packets in Wireless (Ad-Hoc) Mesh Network while keep the connectivity of dynamic nodes. Using the framework, the average network connectivity is kept 18% higher and the lifetime of network lasting more than 2.38% compared with network with Link State Routing mechanism. The simulation notes that the end-to-end delay may increase rapidly if relay nodes are more than five.
DATA TRANSPARENT AUTHENTICATION USING QOD IN HYBRID NETWORKS
Hybrid networks are next generation of wireless networks that could be a
combination of Mobile wireless adhoc (MANET) networks and Wireless Infrastructure
networks. They are increasingly utilized in wireless communications that are extremely
supporting real time transmission with restricted Quality of Service. Invalid reservation and
race condition issues happens in MANET. In existing system, QoS-Oriented Distributed
routing protocol (QOD) is employed to boost the QoS support capability of hybrid networks,
it transforms the packet routing problem to resource scheduling problem that has 5
algorithms. They are, QoS guaranteed neighbor selection algorithm, Distributed packet
scheduling algorithm, Mobility based segment resizing algorithm, Traffic redundant
elimination algorithm and Data redundancy elimination based transmission algorithm. The
main drawback of hybrid networks is so far examined in minimum transmission hops and has
less beneficial feature with restricted number of mobile access points, mobility speeds, and
mobile workloads and with different network sizes. It will extremely perform on random
way point model and less in real mobility model. This paper present Data Transparent
Authentication to authenticates data streams by adjusting interpacket delay. Data Transparent
Authentication while not Communication overhead is an approach which reduces breakdown
of original information or sends out of band authentication data.
Multipath Routing Protocol by Breadth First Search Algorithm in Wireless Mesh...
This document proposes a multipath routing protocol for wireless mesh networks that uses a parallel layer-based approach and breadth-first search algorithm to discover multiple paths between a source and destination. It organizes nodes into layers based on distance from the destination and performs iterative breadth-first searches to find partial paths connecting nodes in lower layers, storing the partial paths. This process repeats until reaching the destination to find all possible paths. The primary path is then elected using an Expected Forwarding Counter metric to select the most reliable path. The protocol was evaluated in NS-2 and showed improved throughput, delivery ratio, and reduced delay compared to other protocols.
ICICCE011
Abstract—Geographic routing also called as Geo routing is a routing principle which relies on the Geographic position information. Geographic routing is the most commonly used routing for MANETs. In Geographic routing each node should be aware of its neighbor’s location to maintain the local topology accuracy. Hence, each node should update its location information through a message called beacon. Existing mechanisms invoke periodic beacon update scheme which consumes the network resources such as energy and bandwidth specifically when the network traffic is high, it creates packet loss in the network and it leads to retransmission of data packet causing additional delay and energy consumption. In this work, adaptive position update is proposed which dynamically adjusts the beacon updation frequency according to the varying network conditions.APU makes use of mobility prediction rule and on demand learning rule for beacon updation.
A QoS Based MAC Protocol For Wireless Ad-hoc Network
Multimedia communication over wireless Ad-hoc networks has become the driving technology for many of the important applications, experiencing dramatic market growth and promising revolutionary experiences in personal communication, gaming, entertainment, military, security, environment monitoring, and more. The advances in wireless communications and growth of real-time applications have necessitated the development of wireless networks that can support high Quality of Service (QoS) and power control. A node in an ad hoc network is normally battery operated which poses a huge constraint on the power consumption of such a node. Hence, designing a power efficient MAC protocol for ad hoc wireless networks is a major challenge. In this paper, we propose a CDMA based power controlled medium access protocol for mobile and ad hoc network (MNA). The protocol conserves power and provides QoS guarantees for multimedia traffics. In that network one of the fundamental challenger in MANETs is how to increase the overall network throughputs well as reading the delay while maintaining how energy consumption for packet processing in communication. simulation results shows that the performance of the protocol with increase in traffic while QoS is better in terms of Energy consumption, throughput, & communication delay than existing protocol.
Mtadf multi hop traffic aware data for warding for congestion control in wir...
The document summarizes a proposed algorithm called MTADF (Multi Hop Traffic-Aware Data Forwarding) for congestion control in wireless sensor networks. The algorithm uses two potential fields - depth potential field and queue length potential field - to route data packets around congested areas along multiple paths. This helps distribute traffic more evenly and utilize less busy nodes, reducing packet drops and improving throughput compared to existing one-hop routing algorithms. The algorithm constructs the two potential fields independently and then combines them to make dynamic forwarding decisions for data packets. Simulations show the MTADF algorithm performs better than previous work in mitigating congestion.

Quick Routing for Communication in MANET using Zone Routing Protocol
rnational Journal of Computational Engineering Resaerch 2014, Volume 4 ~ Issue 11 (November 2014)
Abstract
The paper discusses the voltage control of a critical load bus using dynamic voltage restorer (DVR) in a distribution system. The critical load requires a balanced sinusoidal waveform across its terminals preferably at system nominal frequency of 50Hz .It is assumed that the frequency of the supply voltage can be varied and it is different from the system nominal frequency. The DVR is operated such that it holds the voltage across critical load bus terminals constant at system nominal frequency irrespective of the frequency of the source voltage. In case of a frequency mismatch, the total real power requirement of the critical load bus has to be supplied by the DVR. Proposed method used to compensate for frequency variation, the DC link of the DVR is supplied through an uncontrolled rectifier that provides a path for the real power required by the critical load to flow .A simple frequency estimation technique is discussed which are Discrete Fourier transform (DFT), ANN controller. The present work study the compensation principle and different control strategies of DVR used here are based on DFT, and ANN Controller .Through detailed analysis and simulation studies using MATLAB. It is shown that the voltage is completely controlled across the critical load.

Energy Minimization in Wireless Sensor Networks Using Multi Hop Transmission
This document discusses energy minimization in wireless sensor networks using multi-hop transmissions. It provides background on wireless sensor networks and their components. It then discusses challenges like limited energy and the need for multi-hop transmissions due to limited transmission range. The document outlines the problem of determining the optimal number of cooperating nodes per hop to minimize total energy consumption while meeting an outage probability requirement at each hop. It discusses using cooperative transmissions to increase transmission range through diversity gain while keeping transmit power fixed.
EFFICIENT PACKET DELIVERY APPROACH FOR ADHOC WIRELESS NETWORKS
A wireless ad-hoc network is a collection of nodes which are selfconfiguring,
connected by wireless links. The nodes are free to move randomly and
organize themselves arbitrarily; thus, the network's topology may change rapidly and
unpredictably. These kinds of networks are very flexible and they do not require any
existing infrastructure. Therefore, ad-hoc wireless networks are suitable for temporary
communication links. The biggest challenge in these kinds of networks is to find a path
between the communication end points of nodes that are mobile. Due to the limited
transmission range of wireless interfaces, the communication traffic has to be relayed
over several intermediate nodes to enable the communication between two nodes.
Therefore, these kinds of networks are also called multi-hop ad-hoc networks. The
proposed model is designed to improve the problems of real-time event-based
communication. It improves the packet delivery ratio by prior prediction and reduces
end-to-end packet delay. This in turn improves performance of the routing process
significantly and increases the Quality of Service (QoS).

Performance Analysis of WiMAX Networks with Relay Station
IEEE 802.16 is a Broadband Wireless Access (BWA)
network and thus it is considered to be an alternative solution
to wired broadband technologies. Relay station plays a
promising role of extending the range of Base station for long
distances in WiMAX networks. Relay station is suitable to
areas with limited infrastructure such as rural, hilly and lakes,
where it is difficult to install many Base stations with each
having wired connections and it is also suitable to those phases
where obstacles made the coverage limited. The Relay station
is placed in the network connectivity from Base stations and
extends the coverage of a single Base station. In this paper the
performance analysis of WiMAX technology including Relay
station has been done. This paper also focuses on increasing
number of nodes and distance from base station to the
performance of WiMAX networks.

This document discusses an optimized link state routing protocol based on a cross-layer design for wireless mesh networks. It proposes monitoring link quality at the MAC layer and notifying the network layer of changes, allowing routes to be automatically updated without a refresh phase. This provides seamless connectivity under varying load and mobility. Traditional routing protocols either have fast but vulnerable proactive routes or add overhead with reactive routes. The proposed cross-layer design monitors links continuously and performs vertical handovers to better links to avoid these issues.
LINK-LEVEL PERFORMANCE EVALUATION OF RELAY-BASED WIMAX NETWORK
Relay technology promises appreciable network throughput and coverage enhancement which is required
for high speed wireless cellular systems to function to their optimum. This paper is focused on analysing
the link performance of a relay-based WiMAX network under varying conditions. Comparison is made
between relay and direct link communication in terms of BER (Bit Error Rate), spectral efficiency and
capacity. Effect of multipath fading and user speed on performance are investigated as well. The entire
study involves a hypothetical view as well as MATLAB simulations to predict the benefit of relay
deployment. This is aimed at solving pertinent issues such as coverage holes and cell edge problems which
are associated with traditional non-relay based cellular networks.
Quality of Service in bandwidth adapted hybrid UMTS/WLAN interworking network
Integration of Universal Mobile Telecommunications System (UMTS) and Wireless Local Area Network (WLAN) result in ubiquitous connection for end users. In the integrated network, ensuring the quality of service to users and enhancing capacity of network are prominent issues. Bandwidth adaptation technique is one of the solutions to overcome these issues. Bandwidth adaptation based on per flow and per class schemes were proposed for loosely coupled interworking network. In this paper, hybrid coupled UMTS and WLAN interworking network is analyzed with bandwidth adaptation based on per flow and per class schemes and the performances have been compared. Simulation result shows that the proposed hybrid coupled interworking network with bandwidth adaptation based on per class scheme performs better with enhanced quality of service and network capacity.
MULTI-HOP BANDWIDTH MANAGEMENT PROTOCOL FOR MOBILE AD HOC NETWORKS
An admission control scheme should play the role of a coordinator for flows in a data communication network, to provide the guarantees as the medium is shared. The nodes of a wired network can monitor the medium to know the available bandwidth at any point of time. But, in wireless ad hoc networks, a node must consume the bandwidth of neighboring nodes, during a communication. Hence, the consumption of bandwidth by a flow and the availability of resources to any wireless node strictly depend upon the neighboring nodes within its transmission range. We present a scalable and efficient admission control scheme, Multi-hop Bandwidth Management Protocol (MBMP), to support the QoS requirements
in multi-hop ad hoc networks. We simulate several options to design MBMP and compare the performances of these options through mathematical analysis and simulation results, and compare its effectiveness with the existing admission control schemes through extensive simulations.
Energy Behavior in Ad Hoc Network Minimizing the Number of Hops and Maintaini...
Wireless ad-hoc mesh network is a special kind of network, where all of the nodes move in time. The topology of the network changes as the nodes are in the proximity of each other. Ad-hoc networks are generally self-configuring no stable infrastructure takes a place. In this network, each node should help relaying packets of neighboring nodes using multi-hop routing mechanism. This mechanism is needed to reach far destination nodes to solve problem of dead communication. This multiple traffic "hops" within a wireless mesh network caused dilemma. Wireless mesh network that contain multiple hops become increasingly vulnerable to problems such as energy degradation and rapid increasing of overhead packets. This paper provides a generic routing framework that balances energy efficient broadcast schemes in Wireless (Ad-Hoc) Mesh Network and maintaining connectivity of nodes (mobile terminals). Typically, each node’s activities will consume energy, either for sending packets, receiving or preparing/processing packets. Number of hops, distance of nodes, and size of packet will determine the consumption of energy. The framework is based on the principle that additional relay nodes with appropriate energy and routing metric between source and final destination significantly reduces the energy consumption necessary to deliver packets in Wireless (Ad-Hoc) Mesh Network while keep the connectivity of dynamic nodes. Using the framework, the average network connectivity is kept 18% higher and the lifetime of network lasting more than 2.38% compared with network with Link State Routing mechanism. The simulation notes that the end-to-end delay may increase rapidly if relay nodes are more than five.
DATA TRANSPARENT AUTHENTICATION USING QOD IN HYBRID NETWORKS
Hybrid networks are next generation of wireless networks that could be a
combination of Mobile wireless adhoc (MANET) networks and Wireless Infrastructure
networks. They are increasingly utilized in wireless communications that are extremely
supporting real time transmission with restricted Quality of Service. Invalid reservation and
race condition issues happens in MANET. In existing system, QoS-Oriented Distributed
routing protocol (QOD) is employed to boost the QoS support capability of hybrid networks,
it transforms the packet routing problem to resource scheduling problem that has 5
algorithms. They are, QoS guaranteed neighbor selection algorithm, Distributed packet
scheduling algorithm, Mobility based segment resizing algorithm, Traffic redundant
elimination algorithm and Data redundancy elimination based transmission algorithm. The
main drawback of hybrid networks is so far examined in minimum transmission hops and has
less beneficial feature with restricted number of mobile access points, mobility speeds, and
mobile workloads and with different network sizes. It will extremely perform on random
way point model and less in real mobility model. This paper present Data Transparent
Authentication to authenticates data streams by adjusting interpacket delay. Data Transparent
Authentication while not Communication overhead is an approach which reduces breakdown
of original information or sends out of band authentication data.

This document proposes a multipath routing protocol for wireless mesh networks that uses a parallel layer-based approach and breadth-first search algorithm to discover multiple paths between a source and destination. It organizes nodes into layers based on distance from the destination and performs iterative breadth-first searches to find partial paths connecting nodes in lower layers, storing the partial paths. This process repeats until reaching the destination to find all possible paths. The primary path is then elected using an Expected Forwarding Counter metric to select the most reliable path. The protocol was evaluated in NS-2 and showed improved throughput, delivery ratio, and reduced delay compared to other protocols.
ICICCE011
Abstract—Geographic routing also called as Geo routing is a routing principle which relies on the Geographic position information. Geographic routing is the most commonly used routing for MANETs. In Geographic routing each node should be aware of its neighbor’s location to maintain the local topology accuracy. Hence, each node should update its location information through a message called beacon. Existing mechanisms invoke periodic beacon update scheme which consumes the network resources such as energy and bandwidth specifically when the network traffic is high, it creates packet loss in the network and it leads to retransmission of data packet causing additional delay and energy consumption. In this work, adaptive position update is proposed which dynamically adjusts the beacon updation frequency according to the varying network conditions.APU makes use of mobility prediction rule and on demand learning rule for beacon updation.
A QoS Based MAC Protocol For Wireless Ad-hoc Network
Multimedia communication over wireless Ad-hoc networks has become the driving technology for many of the important applications, experiencing dramatic market growth and promising revolutionary experiences in personal communication, gaming, entertainment, military, security, environment monitoring, and more. The advances in wireless communications and growth of real-time applications have necessitated the development of wireless networks that can support high Quality of Service (QoS) and power control. A node in an ad hoc network is normally battery operated which poses a huge constraint on the power consumption of such a node. Hence, designing a power efficient MAC protocol for ad hoc wireless networks is a major challenge. In this paper, we propose a CDMA based power controlled medium access protocol for mobile and ad hoc network (MNA). The protocol conserves power and provides QoS guarantees for multimedia traffics. In that network one of the fundamental challenger in MANETs is how to increase the overall network throughputs well as reading the delay while maintaining how energy consumption for packet processing in communication. simulation results shows that the performance of the protocol with increase in traffic while QoS is better in terms of Energy consumption, throughput, & communication delay than existing protocol.

The document summarizes a proposed algorithm called MTADF (Multi Hop Traffic-Aware Data Forwarding) for congestion control in wireless sensor networks. The algorithm uses two potential fields - depth potential field and queue length potential field - to route data packets around congested areas along multiple paths. This helps distribute traffic more evenly and utilize less busy nodes, reducing packet drops and improving throughput compared to existing one-hop routing algorithms. The algorithm constructs the two potential fields independently and then combines them to make dynamic forwarding decisions for data packets. Simulations show the MTADF algorithm performs better than previous work in mitigating congestion.

Quick Routing for Communication in MANET using Zone Routing Protocol
rnational Journal of Computational Engineering Resaerch 2014, Volume 4 ~ Issue 11 (November 2014)
Abstract
The paper discusses the voltage control of a critical load bus using dynamic voltage restorer (DVR) in a distribution system. The critical load requires a balanced sinusoidal waveform across its terminals preferably at system nominal frequency of 50Hz .It is assumed that the frequency of the supply voltage can be varied and it is different from the system nominal frequency. The DVR is operated such that it holds the voltage across critical load bus terminals constant at system nominal frequency irrespective of the frequency of the source voltage. In case of a frequency mismatch, the total real power requirement of the critical load bus has to be supplied by the DVR. Proposed method used to compensate for frequency variation, the DC link of the DVR is supplied through an uncontrolled rectifier that provides a path for the real power required by the critical load to flow .A simple frequency estimation technique is discussed which are Discrete Fourier transform (DFT), ANN controller. The present work study the compensation principle and different control strategies of DVR used here are based on DFT, and ANN Controller .Through detailed analysis and simulation studies using MATLAB. It is shown that the voltage is completely controlled across the critical load.

EFFICIENT PACKET DELIVERY APPROACH FOR ADHOC WIRELESS NETWORKS
A wireless ad-hoc network is a collection of nodes which are selfconfiguring,
connected by wireless links. The nodes are free to move randomly and
organize themselves arbitrarily; thus, the network's topology may change rapidly and
unpredictably. These kinds of networks are very flexible and they do not require any
existing infrastructure. Therefore, ad-hoc wireless networks are suitable for temporary
communication links. The biggest challenge in these kinds of networks is to find a path
between the communication end points of nodes that are mobile. Due to the limited
transmission range of wireless interfaces, the communication traffic has to be relayed
over several intermediate nodes to enable the communication between two nodes.
Therefore, these kinds of networks are also called multi-hop ad-hoc networks. The
proposed model is designed to improve the problems of real-time event-based
communication. It improves the packet delivery ratio by prior prediction and reduces
end-to-end packet delay. This in turn improves performance of the routing process
significantly and increases the Quality of Service (QoS).

This brief presents a fast-acquisition 11-bit all-digital delay-locked loop (ADDLL) using a novel starting-bit prediction algorithm for the successive-approximation register (SBP-SAR). It can effectively eliminate the harmonic lock and the false lock. The achievable acquisition time is within 17.5-23.5 or 17.5-32.5 clock cycles when the ADDLL works at the low or high clock rate, respectively. The digital-controlled delay line and the SBP-SAR of the ADDLL chip are synthesized using Taiwan Semiconductor Manufacturing Company's (TSMC's) 0.18-μm CMOS cell library. The proposed ADDLL can operate at a clock frequency from 60 MHz to 1.1 GHz.

This document describes a proposed stochastic implementation of the Sauvola local image thresholding algorithm to reduce area, power consumption, and faults compared to a conventional implementation. The stochastic implementation converts pixel values and intermediate results to stochastic bit streams, uses stochastic multiplying counters (SMCs) to calculate averages and standard deviations in parallel, and a stochastic comparator to determine binary output values. Experimental results using Xilinx 14.2 show the stochastic implementation requires less time, area and power while being more fault tolerant.

A Dynamically Reconfigurable Multi-ASIP Architecture for Multistandard and Multimode Turbo Decoding
The multiplication of wireless communication standards is introducing the need of flexible and reconfigurable multistandard baseband receivers. In this context, multiprocessor turbo decoders have been recently developed in order to support the increasing flexibility and throughput requirements of emerging applications. However, these solutions do not sufficiently address reconfiguration performance issues, which can be a limiting factor in the future. This brief presents the design of a reconfigurable multiprocessor architecture for turbo decoding achieving very fast reconfiguration without compromising the decoding performances.

Interleaved digital power factor correction based on the sliding mode approach
Interleaved Digital Power Factor Correction Based on the Sliding-Mode Approach
This study describes a digitally controlled power factor correction (PFC) system based on two interleaved boost converters operating with pulsewidth modulation (PWM). Both converters are independently controlled by an inner control loop based on a discrete-time sliding-mode (SM) approach that imposes loss-free resistor (LFR) behavior on each cell. The switching surface implements an average current-mode controller so that the power factor (PF) is high. The SM-based digital controller is designed to operate at a constant switching frequency so that the interleaving technique, which is recommended for ac-dc power conversion systems higher than 1 kW, can be readily applied. An outer loop regulates the output voltage by means of a discrete-time proportional-integral (PI) compensator directly obtained from a discrete-time small-signal model of the ideal sliding dynamics. The control law proposed has been validated using numerical simulations and experimental results in a 2-kW prototype.

Bumpless control for reduced thd in power factor correction circuits
Bumpless Control for Reduced THD in Power Factor Correction Circuits
It is well known that power factor correction (PFC) circuits suffer from two fundamentally different operating modes over a given AC input cycle. These two modes, continuous conduction mode (CCM) and discontinuous conduction mode (DCM), have very different frequency-response characteristics that can make control design for PFC circuits challenging. The problem is exacerbated by attempts to improve efficiency by dynamically adjusting the PWM switching frequency based on the load. Adjusting the PWM frequency based on the load limits controller bandwidth and restricts dynamic performance. Prior work has made use of multiple controllers, however, they have not addressed the discontinuity (bump) that exists when switching between controllers. In this paper, bumpless controllers will be synthesized for a 750 watt, semi-bridgeless PFC for the CCM-DCM operating modes.

A bidirectional single-stage three-phase Rectifier with high-frequency Isolation and power factor Correction
This paper proposes a single-stage three-phase rectifier with high-frequency isolation, power factor correction, and bidirectional power flow. The presented topology is adequate for dc grids (or smart-grids), telecommunications (telecom) power supplies, and more recent applications such as electric vehicles. The converter is based on the three-phase version of the dual active bridge (DAB) associated with the three-state-switching cell (3SSC), whose power flow between the primary and secondary sides is controlled by the phase-shift angle. A theoretical analysis is presented and validated through simulation and experimental.

A bidirectional three level llc resonant converter with pwam control
A Bidirectional Three-Level LLC Resonant Converter With PWAM Control
This paper proposes a bidirectional three-level LLC resonant converter with a new pulse width and amplitude modulation control method. With different control signals, it has three different operation modes with different voltage gains. Therefore, it can achieve wide voltage gain range by switching among these three modes, which is attractive for energy storage system applications needing wide voltage variation. The proposed topology operates with constant switching frequency, which is easy to implement with digital control, and it can achieve soft switching for all the switches and diodes in the circuit as a conventional LLC resonant converter. The performance of the proposed converter is validated by the experimental results from a 1-kW prototype with 20 A maximum output current.

This document describes a proposed transformer-less inverter topology for grid-tied photovoltaic systems. The existing dual-parallel buck converter topology has issues where the grid can short circuit if there is no dead time between switches. The proposed topology addresses this by using six MOSFET switches and six diodes in a configuration that allows reactive power injection while overcoming reliability issues. It has advantages like utilizing only MOSFET switches, low leakage current, and not requiring PWM dead times. The proposed single-phase inverter is intended for grid-tied PV applications.

Highly Reliable Transformerless Photovoltaic Inverters With Leakage Current and Pulsating Power Elimination
This paper presents a transformerless inverter topology, which is capable of simultaneously solving leakage current and pulsating power issues in grid-connected photovoltaic (PV) systems. Without adding any additional components to the system, the leakage current caused by the PV-to-ground parasitic capacitance can be bypassed by introducing a common-mode (CM) conducting path to the inverter. The resulting ground leakage current is therefore well controlled to be below the regulation limit. Furthermore, the proposed inverter can also eliminate the well-known double-line-frequency pulsating power that is inherent in single-phase PV systems. By properly injecting CM voltages to the output filter capacitors, the pulsating power can be decoupled from the dc-link. Therefore, it is possible to use long-lifetime film capacitors instead of electrolytic capacitors to improve the reliability of the PV system. The mechanism of leakage current suppression and the closed-loop control of pulsating power decoupling are discussed in this paper in detail. A 500-W prototype was also built and tested in the laboratory, and both simulation and experimental results are finally presented to show the excellent performance of the proposed PV inverter.

Grid-Current-Feedback Active Damping for LCL Resonance in Grid-Connected Voltage-Source Converters
This paper investigates active damping of LCL-filter resonance in a grid-connected voltage-source converter with only grid-current feedback control. Basic analysis in the s-domain shows that the proposed damping technique with a negative high-pass filter along its damping path is equivalent to adding a virtual impedance across the grid-side inductance. This added impedance is more precisely represented by a series RL branch in parallel with a negative inductance. The negative inductance helps to mitigate phase lag caused by time delays found in a digitally controlled system. The mitigation of phase-lag, in turn, helps to shrink the region of nonminimum-phase behavior caused by negative virtual resistance inserted unintentionally by most digitally implemented active damping techniques. The presented high-pass-filtered active damping technique with a single grid-current feedback loop is thus a more effective technique, whose systematic design in the z-domain has been developed in this paper. For verification, experimental testing has been performed with results obtained matching the theoretical expectations closely.

Delay-Dependent Stability of Single-Loop Controlled Grid-Connected Inverters with LCL Filters
LCL filters have been widely used for grid-connected inverters. However, the problem that how time delay affects the stability of digitally controlled grid-connected inverters with LCL filters has not been fully studied. In this paper, a systematic study is carried out on the relationship between the time delay and stability of single-loop controlled grid-connected inverters that employ inverter current feedback (ICF) or grid current feedback (GCF). The ranges of time delay for system stability are analyzed and deduced in the continuous s-domain and discrete z-domain. It is shown that in the optimal range, the existence of time delay weakens the stability of the ICF loop, whereas a proper time delay is required for the GCF loop. The present work explains, for the first time, why different conclusions on the stability of ICF loop and GCF loop have been drawn in previous studies. To improve system stability, a linear predictor-based time delay reduction method is proposed for ICF, while a time delay addition method is used for GCF. A controller design method is then presented that guarantees adequate stability margins. The delay-dependent stability study is verified by simulation and experiment.

Pass byo bring your own picture for securing graphical passwords
This document describes PassBYOP, a new graphical password scheme that uses live video of a physical token (such as a photo on a mobile phone) rather than static digital images. Three feasibility studies examine its reliability, usability, and security against observation attacks. Results found passwords based on image features to be viable, with task times and error rates comparable to prior schemes. Using a user-owned physical token increased security against observation without additional user burden, showing promise for more secure graphical passwords.

Analyzing ad library updates in android apps
The document discusses analyzing ad library updates in Android apps. It finds that almost half of Android apps underwent ad library updates over a 12 month period, where an ad library was added, removed, or updated. For nearly 14% of app updates with an ad library update, no changes were made to the app's core functionality, suggesting maintaining ad libraries requires substantial effort. The proposed system compares how apps are updated over time to determine if an update includes ad library changes, core changes, or both.

Web : www.lemenizinfotech.com / www.ieeemaster.com Mail : projects@lemenizinfotech.com A DISTRIBUTED THREE-HOP ROUTING PROTOCOL TO INCREASE THE CAPACITY OF HYBRID WIRELESS NETWORKS ABSTRACT Hybrid wireless networks combining the advantages of both mobile ad-hoc networks and infrastructure wireless networks have been receiving increased attention due to their ultra-high performance. An efficient data routing protocol is important in such networks for high network capacity and scalability. However, most routing protocols for these networks simply combine the ad-hoc transmission mode with the cellular transmission mode, which inherits the drawbacks of ad-hoc transmission. This Project presents a Distributed Three-hop Routing protocol (DTR) for hybrid wireless networks. To take full advantage of the widespread base stations, DTR divides a message data stream into segments and transmits the segments in a distributed manner. It makes full spatial reuse of a system via its high speed ad-hoc interface and alleviates mobile gateway congestion via its cellular interface. Furthermore, sending segments to a number of base stations simultaneously increases throughput and makes full use of widespread base stations. In addition, DTR significantly reduces overhead due to short path lengths and the elimination of route discovery and maintenance. DTR also has a congestion control algorithm to avoid overloading base stations. Theoretical analysis and simulation results show the superiority of DTR in comparison with other routing protocols in terms of throughput capacity, scalability and mobility resilience. The results also show the effectiveness of the congestion control algorithm in balancing the load between base stations.
