An enhanced group mobility protocol for 6 lowpan based wireless body area net...
The document proposes an enhanced group mobility protocol for 6LoWPAN-based wireless body area networks (WBANs) to reduce handoff delay and signaling costs. It describes how proxy mobile IPv6 (PMIPv6) can be used to manage network-based mobility but has limitations for group-based WBAN mobility. The proposed protocol uses a new format for router solicitation and router advertisement messages that can carry information for multiple sensor identifiers, reducing the number of control messages needed during handoffs. Simulation results show the proposed protocol reduces handoff delay, signaling costs, packet loss, and overhead on the mobile access gateway compared to existing group-based PMIPv6 protocols.
Prediction Algorithm for Mobile Ad Hoc Network Connection Breaks
A Mobile Ad-Hoc Network (MANET) is a decentralized network of mobile node that are connected to an arbitrary topology via wireless connections. The breakdown of the connecting links between adjacent nodes will probably lead to the loss of the transferred data packets. In this research, we proposed an algorithm for link prediction (LP) to enhance the link break provision of the ad hoc on-demand remote protocol (AODV). The proposed algorithm is called the AODV Link Break Prediction (AODVLBP). The AODVLBP prevents link breaks by the use of a predictive measure of the changing signal. The AODVLBP was evaluated using the network simulator version 2.35 (NS2) and compared with the AODV Link prediction (AODVLP) and the AODV routing protocols. The simulation results reveal the effectiveness of AODVLBP in improving network performance in terms of average end-to-end delay, packet delivery ratio, packet overhead ratio, and packet drop-neighbour break.

IMPLEMENTATION AND COMPARISION OF DATA LINK QUALITY SCHEME ON ODMRP AND ADMR ...
An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any fixed network infrastructure or centralized administration. In order to enable communication within the network, a routing protocol is needed to discover routes between nodes. The primary goal of ad hoc network routing protocols is to establish routes between node pairs so that messages may be delivered reliably and in a timely manner. The objective of any routing protocol is to have packet delivered with least possible cost in terms of receiving power, transmission power, battery energy consumption and distance. All these factors basically effect the establishment of link between the mobile nodes and liability and stability of these links. In this paper, we implement a data link quality scheme on two protocols ODMRP and ADMR and compare them on the bases link quality and link stability.

The importance of IPv6 Routing Protocol for Low power and Lossy Networks (LLNs), also called RPL, has motivated in the development of a robust and quality of service (QoS) oriented Multi-Constraints Adaptive Link Quality Index (MALQI) based routing protocol. Unlike classical RPL protocols, MALQI enables mobile-RPL while ensuring fault-resilient, reliable and QoS communication over LLNs. MALQI protocol exploits key novelties such as signal strength based mobile node positioning, average received signal strength indicator (ARSSI) and ETX based objective function for fault tolerant best forwarding path selection. The functional architecture of MALQI enables it to be used as the parallel to the link layer RPL that even in the case of link failure can assist efficient data delivery over LLNs. Once detecting link outage, MALQI can execute node discover and best forwarding path selection to assist QoS delivery. Contiki-Cooja based simulation reveals that MALQI based mobile-RPL outperforms other state-of-art routing protocols.

SEECH is a secure and energy efficient centralized routing protocol for hierarchical wireless sensor networks. It utilizes a base station to efficiently form clusters based on sensor node energy levels and neighbor information. The base station selects cluster heads that have above average energy and many neighbors. Cluster heads then schedule sensor node transmissions to reduce interference and aggregate and encrypt sensor data before transmitting to the base station or other cluster heads. SEECH aims to prolong network lifetime by minimizing energy consumption through efficient clustering and routing.
Priority based bandwidth allocation in wireless sensor networks
Most of the sensor network applications need real time communication and the need for deadline aware real time communication is becoming eminent in these applications. These applications have different dead line requirements also. The real time applications of wireless sensor networks are bandwidth sensitive and need higher share of bandwidth for higher priority data to meet the dead line requirements. In this paper we focus on the MAC layer modifications to meet the real time requirements of different priority data.Bandwidth partitioning among different priority transmissions is implemented through MAC layer modifications. The MAC layer implements a queuing model that supports lower transfer rate for lower
priority packets and higher transfer rate for real
time packets with higher priority, minimizing the end to
end delay. The performance of the algorithm is evaluated with varying node distribution

Analysis of Link State Resource Reservation Protocol for Congestion Managemen...
With the wide spread of WiFi hotspots, concentrated traffic workload on Smart Web (SW) can slow down
the network performance. This paper presents a congestion management strategy considering real time
activities in today’s smart web. With the SW context, cooperative packet recovery using resource
reservation procedure for TCP flows was adapted for mitigating packet losses. This is to maintain data
consistency between various access points of smart web hotspot. Using a real world scenario, it was
confirmed that generic TCP cannot handle traffic congestion in a SW hotspot network. With TCP in
scalable workload environments, continuous packet drops at the event of congestion remains obvious. This
is unacceptable for mission critical domains. An enhanced Link State Resource Reservation Protocol (LSRSVP)
which serves as dynamic feedback mechanism in smart web hotspots is presented. The contextual
behaviour was contrasted with the generic TCP model. For the LS-RSVP, a simulation experiment for TCP
connection between servers at the remote core layer and the access layer was carried out while using
selected benchmark metrics. From the results, under realistic workloads, a steady-state throughput
response was achieved by TCP LS-RSVP to about 3650Bits/secs compared with generic TCP plots in a
previous study. Considering network service availability, this was found to be dependent on fault-tolerance
of the hotspot network. From study, a high peak threshold of 0.009 (i.e. 90%) was observed. This shows
fairly acceptable service availability behaviour compared with the existing TCP schemes. For packet drop
effects, an analysis on the network behaviour with respect to the LS-RSVP yielded a drop response of about
0.000106 bits/sec which is much lower compared with the case with generic TCP with over 0.38 bits/sec.
The latency profile of average FTP download response was found to be 0.030secs, but with that of FTP
upload response, this yielded about 0.028 sec. The results from the study demonstrate efficiency and
optimality for realistic loads in Smart web contexts.

This document summarizes a research paper that proposes a new routing algorithm called the Link Prediction Routing Algorithm (LPRA) for mobile ad hoc networks. The LPRA aims to establish reliable links and perform persistent data forwarding based on predicting node and link lifetimes. It does so by selecting routes with the longest predicted lifetimes. The algorithm is evaluated through simulation and shown to improve performance metrics like throughput, delivery ratio, and delay compared to existing techniques. It aims to efficiently route data in unstable mobile ad hoc networks where topology frequently changes.

This document analyzes the performance of LTE networks using random linear network coding (RLNC) at the application layer. The study uses a simulation setup with a remote host, eNodeB, and user equipment to send coded and uncoded packets. The results show that applying RLNC at the application layer improves throughput but increases packet delay compared to not using network coding. MIMO antenna techniques are also found to provide higher throughput than SISO.

This paper demonstrates the robustness of active queue management techniques to varying load, link capacity and propagation delay in a wireless environment. The performances of four standard controllers used in Transmission Control Protocol/Active Queue Management (TCP/AQM) systems were compared. The active queue management controllers were the Fixed-Parameter Proportional Integral (PI), Random Early Detection (RED), Self-Tuning Regulator (STR) and the Model Predictive Control (MPC). The robustness of the congestion control algorithm of each technique was documented by simulating the varying conditions using MATLAB® and Simulink® software. From the results obtained, the MPC controller gives the best result in terms of response time and controllability in a wireless network with varying link capacity and propagation delay. Thus, the MPC controller is the best bet when adaptive algorithms are to be employed in a wireless network environment. The MPC controller can also be recommended for heterogeneous networks where the network load cannot be estimated.
TRIDNT: THE TRUST-BASED ROUTING PROTOCOL WITH CONTROLLED DEGREE OF NODE SELFI...
In Mobile ad-hoc network, nodes must cooperate to achieve the routing purposes. Node misbehaviour due to selfish or malicious intention could significantly degrade the performance of MANET because most existing routing protocols in MANET are aiming at finding most efficiency path. In this paper, we propose a Two node-disjoint Routes protocol for Isolating Dropper Node in MANET (TRIDNT) to deal with misbehaviour in MANET. TRIDNT allows some degree of selfishness to give an incentive to the selfish nodes to declare itself to its neighbours, which reduce the misbehaving nodes searching time. In TRIDNT two node-disjoint routes between the source and destination are selected based on their trust values. We use both DLL-ACK and end-to-end TCP-ACK to monitor the behaviour of routing path nodes: if a malicious behaviour is detected then the path searching tool starts to identify the malicious nodes and isolate them. Finally by using a mathematical analysis we find that our proposed protocol reduces the searching time of malicious nodes comparing to the route expected life time, and avoids the isolated misbehaving node from sharing in all future routes, which improve the overall network throughput.

This summary provides an overview of a document that reviews several algorithms aimed at improving TCP congestion control and addressing route failures in mobile ad hoc networks (MANETs).
The document begins with an introduction to MANETs and the issues they present for TCP, as TCP was designed for wired networks and interprets all packet losses as congestion. It then analyzes and compares five different algorithms that have been proposed to help TCP distinguish between losses due to route failures versus congestion. These algorithms aim to improve network performance metrics like throughput, packet delivery ratio, and end-to-end delay. The document concludes that while these algorithms approach the problem of route failures and TCP performance degradation in different ways, their overall goal is the

This paper proposes a load balancing algorithm using fuzzy logic so that maximum Quality of Experience can
be achieved. Avoidance of congestion is one of the major performance objectives of traffic engineering in
MPLS networks. Load balancing can prevent the congestion caused due to inefficient allocation of network
resources. Another aspect of the network performance is Quality of Experience (QoE). QoE in
telecommunications terminology, it is a measurement used to determine how well that network is satisfying the
end user's requirements. The Mean Opinion Score (MOS) is an important factor in determining the QoE. MOS
is a measurement of the quality delivered by the network based on human perception at the destination end.
Specifically we can tell mean opinion score (MOS) provides a numerical indication of the perceived quality of
received media after compression and/or transmission.

11.a review of improvement in tcp congestion control using route failure det...
This summary provides an overview of a document that reviews several algorithms aimed at improving TCP congestion control and addressing route failures in mobile ad hoc networks (MANETs).
The document begins with an introduction to MANETs and the issues they present for TCP, as TCP was designed for wired networks and interprets all packet losses as congestion. It then analyzes and compares five different algorithms that have been proposed to help TCP distinguish between losses due to route failures versus congestion. These algorithms aim to improve network performance metrics like throughput, packet delivery ratio, and end-to-end delay. The document concludes that while these algorithms approach the problem of route failures and TCP performance degradation in different ways, their overall goal is the
Traffic Engineering and Quality of Experience in MPLS Network by Fuzzy Logic ...
This paper proposes a load balancing algorithm using fuzzy logic so that maximum Quality of Experience can
be achieved. Avoidance of congestion is one of the major performance objectives of traffic engineering in
MPLS networks. Load balancing can prevent the congestion caused due to inefficient allocation of network
resources. Another aspect of the network performance is Quality of Experience (QoE). QoE in
telecommunications terminology, it is a measurement used to determine how well that network is satisfying the
end user's requirements. The Mean Opinion Score (MOS) is an important factor in determining the QoE. MOS
is a measurement of the quality delivered by the network based on human perception at the destination end.
Specifically we can tell mean opinion score (MOS) provides a numerical indication of the perceived quality of
received media after compression and/or transmission.

Comprehensive survey on routing protocols for IoT
This document provides an overview of routing protocols for the Internet of Things (IoT). It defines IoT and routing protocols, describes common routing algorithms like distance vector and link state, and discusses specific protocols such as RPL, RIP, and OSPF. It also covers clustering in wireless sensor networks and the LEACH clustering protocol.
Network Protocols
Network protocols are sets of rules that govern communications between computers on a network. They configure characteristics like cabling, topology, and bandwidth. The OSI model is an industry standard that defines seven layers of functions for communication between any two points on a network. Each layer has a specific role, with the lowest layers involving physical networking and higher layers dealing with applications and data. Protocols at each layer work together to establish consistent rules for exchanging data and messages between networked devices.
bluetooth protocol stack.pptx
The document discusses the Bluetooth protocol stack which is divided into core specifications and profile specifications. The core protocols include the radio layer, baseband layer, link manager protocol, L2CAP, service discovery protocol, RFCOMM, and HCI. The radio layer uses frequency hopping. The baseband layer establishes connections and handles packet transmission. L2CAP supports protocol multiplexing and segmentation. RFCOMM emulates serial ports over L2CAP. The stack provides for wireless connection between Bluetooth devices.
Internet Traffic Engineering
1) MPLS introduces labels that are prefixed to packet headers and allows forwarding based on these labels instead of long IP addresses, enabling traffic engineering.
2) Labels are assigned based on forward equivalence classes which group packets that should follow the same path. This path is called a label switched path (LSP).
3) Generalized MPLS (GMPLS) extends MPLS to support a wider range of network types and interfaces beyond IP routers, including support for optical and time-division multiplexing networks. It enhances signaling protocols and introduces hierarchical LSP setup.
Mpls
MPLS (Multi-Protocol Label Switching) simplifies packet forwarding by assigning labels to packets and using these labels for forwarding instead of long network addresses. It allows for traffic engineering and quality of service by establishing Label Switched Paths (LSPs) to direct different types of traffic over specific paths. MPLS supports various Layer 2 and Layer 3 protocols and improves network performance and scalability compared to traditional IP routing. It is widely used to implement virtual private networks (VPNs) across shared infrastructures.
HDLC and Point to point protocol
HDLC and PPP are data link layer protocols used to transmit data between network nodes. HDLC organizes data into frames for transmission and ensures successful arrival. PPP establishes direct connections between two nodes, such as routers, and provides authentication and encryption. Both protocols provide reliable data transmission and flow control and were designed to work with various network layer protocols like IP and IPX.

IJSRED-V1I1P4
This document discusses Multi Protocol Label Switching (MPLS), which is a networking technology that directs data from one network node to the next based on small path labels rather than long network addresses. MPLS provides faster packet forwarding for IP networks by using short path labels instead of long IP addresses for routing packets. It works by assigning a special label or identifier to each network packet. These labels are then used to route packets through the network instead of looking up the IP address. The document discusses how MPLS is integrated with IP networks, signaling protocols used in MPLS, and compares MPLS to other technologies like Frame Relay and ATM.

- 2. The Logical Link Control and Adaptation Layer Protocol (L2CAP) is layered over the Baseband Protocol and resides in the data link layer. L2CAP provides connection-oriented and connectionless data services to upper layer protocols with protocol multiplexing capability, segmentation and reassembly operation, and group abstractions. L2CAP permits higher level protocols and applications to transmit and receive L2CAP data packets up to 64 kilobytes in length. Two link types are supported for the Baseband layer : Synchronous Connection-Oriented (SCO) links and Asynchronous Connection-Less (ACL) links. SCO links support real-time voice traffic using reserved bandwidth. ACL links support best effort traffic. The L2CAP Specification is defined for only ACL links and no support for SCO links is planned. .
