Delay Limited Transmission Techniques with Low Density Parity Check Method of...
In a Quasi stationary sources time utilization takes a major role. To implement the delay limited transmission of Quasi stationary sources over block fading channels is considered. Here to reduce the delay we propose the power adaption schemes here we can implement the analytical distortion outage probability as performance measure and also derive the power of each transmission scheme.transmission are presented. The first one is optimizedfor fixed rate transmission, and hence enjoys simplicity of implementation. The second one is a high performance scheme, which also benefits from optimized rate adaptation with respect to source and channel states.for High SNR regime ,the asymptotic outage distortion gain are derived.here another two schemes with fixed transmission powers and adaptive rates are consider for comparisions here source and channel coded optimized power adaption scheme outperforms compare to other schemes,by adding the low density parity check method the delay can be reduced rapidly by using the proposed method.
Fuzzy Optimized Metric for Adaptive Network Routing
Network routing algorithms used today calculate least cost (shortest) paths between nodes. The cost of a path is the sum of the cost of all links on that path. The use of a single metric for adaptive routing is insufficient to reflect the actual state of the link. In general, there is a limitation on the accuracy of the link state information obtained by the routing protocol. Hence it becomes useful if two or more metrics can be associated to produce a single metric that can describe the state of the link more accurately. In this paper, a fuzzy inference rule base is implemented to generate the fuzzy cost of each candidate path to be used in routing the incoming calls. This fuzzy cost is based on the crisp values of the different metrics; a fuzzy membership function is defined. The parameters of these membership functions reflect dynamically the requirement of the incoming traffic service as well as the current state of the links in the path. And this paper investigates how three metrics, the mean link bandwidth, queue utilization and the mean link delay, can be related using a simple fuzzy logic algorithm to produce a optimized cost of the link for a certain interval that is more „precise‟ than either of the single metric, to solve routing problem .

Stochastic analysis of random ad hoc networks with maximum entropy deployments
In this paper, we present the first stochastic analysis of the link performance of an ad hoc network modelled
by a single homogeneous Poisson point process (HPPP). According to the maximum entropy principle, the
single HPPP model is mathematically the best model for random deployments with a given node density.
However, previous works in the literature only consider a modified model which shows a discrepancy in the
interference distribution with the more suitable single HPPP model. The main contributions of this paper
are as follows. 1) It presents a new mathematical framework leading to closed form expressions of the
probability of success of both one-way transmissions and handshakes for a deployment modelled by a
single HPPP. Our approach, based on stochastic geometry, can be extended to complex protocols. 2) From
the obtained results, all confirmed by comparison to simulated data, optimal PHY and MAC layer
parameters are determined and the relations between them is described in details. 3) The influence of the
routing protocol on handshake performance is taken into account in a realistic manner, leading to the
confirmation of the intuitive result that the effect of imperfect feedback on the probability of success of a
handshake is only negligible for transmissions to the first neighbour node.

This document describes the LEACH (Low-Energy Adaptive Clustering Hierarchy) protocol for wireless microsensor networks. LEACH utilizes randomized rotation of cluster heads to distribute the energy load evenly among the sensors and achieves longer system lifetime. It uses localized coordination and control for data transfers to reduce global network communication. LEACH allows adaptive clustering and uses data aggregation in the clusters to reduce global data transmission and improve system scalability and energy efficiency. Simulation results show that LEACH distributes energy load evenly and outperforms other routing protocols by achieving up to a factor of 4 times increase in system lifetime.

A Low Overhead Reachability Guaranteed Dynamic Route Discovery Mechanism for ...
A crucial issue for a mobile ad hoc network is the handling of a large number of nodes. As more nodes join
the mobile ad hoc network, contention and congestion are more likely. The on demand routing protocols
which broadcasts control packets to discover routes to the destination nodes, generate a high number of
broadcast packets in a larger networks causing contention and collision. We propose an efficient route
discovery protocol, which reduces the number of broadcast packet, using controlled flooding technique.
The simulation results show that the proposed probabilistic flooding decreases the number of control
packets floating in the network during route discovery phase, without lowering the success ratio of path
discoveries. Furthermore, the proposed method adapts to the normal network conditions. The results show
that up to 70% of control packet traffic is saved in route discovery phase when the network is denser.

Unit i packet switching networks
Packet-switching networks transfer information as packets that may experience random delays and loss. There are two main approaches: connectionless datagram service which routes packets independently, and connection-oriented virtual circuits which establish paths for packets belonging to a connection. Routing determines the best paths for packets using distributed algorithms that adapt to network changes. Large packet switches use techniques like self-routing, shared memory, and crossbar switches to efficiently route high volumes of packets.

This document proposes a discrete wavelet transform (DWT)-based channel estimation method for MIMO-OFDM systems. It describes the transmitter and receiver structures of a wavelet-based OFDM system with multiple antennas. At the transmitter, data is modulated using inverse DWT and transmitted over frequency-selective channels. At the receiver, received signals are processed using DWT to estimate the channel. Least squares and minimum mean squared error estimation techniques are discussed. Simulation results show the DWT-based system achieves better bit error rate performance than conventional FFT-based OFDM.
Achieving Optimum Value of k in a K-fold Multicast Network with Buffer using ...
Multicast network is widely used for effective communication, transmission and performance
optimizations of a network. In this paper, a new model has been developed to determine a
suitable value of the fold k of a k-fold multicast network under different traffic loads under
Poisson traffic with finite queue at each node. We have derived stationary distribution for the
network states and then derived expressions for the network throughput and the blocking
probability of the network. It has been found in this research work that the network throughput
increases very fast as we increase the fold number. However, at a certain value of the fold, the
blocking probability ceases to increase and it remains constant. We have also observed that as
the offered traffic is increased, the throughput also increases. Moreover, the system parameter k
is increased, the blocking probability decreases. However, after an optimum value of k, the
blocking probability remains constant for a particular value of the offered traffic. In fact, in this
paper, by evaluating the performance of a k-fold multicast network, our developed model improves the performance of a multicast network.

FUZZY-CONTROLLED POWER-AWARE PROACTIVE-ACKNOWLEDGEMENT BASED BROADCASTING (FP...
Network-wide broadcasting is a fundamental operation for mobile ad hoc networks. Inbroadcasting, a source node sends a message to all other nodes in the network. Under ordinary
flooding procedure, each node transmits the broadcast message to all of its 1-hop downlinkneighbours, i.e. all nodes residing within its radio-range. Receiving the broadcast message all those downlink neighbours reply with an acknowledgement. Since in an ad hoc network a node
may have multiple uplink neighbours, in ordinary flooding procedure, a node is supposed to receive the broadcast message from all those uplink neighbours and send acknowledgement to all of them, generating huge message contention and collision. This is popularly referred to as
the broadcast storm problem. The present article is focused to remove the broadcast redundancy within 2-hop neighbourhood and beyond, as much as possible by prioritizing the 1-
hop downlink neighbours of a node. Priority of a 1-hop downlink neighbour of a node ni increases if it is equipped with a large number of 1-hop downlink neighbours, large radiorange,
high remaining battery power and very small number of uplink neighbours closer to the broadcast source than ni
. ni waits a predefined amount of time to receive proactive
acknowledgements from the 1-hop downlink neighbours having less priority. If it does not receive acknowledgement from those downlink neighbours within the waiting time, it sends the
broadcast message to them. A fuzzy controller named Priority Assignor (PA) is embedded in every node that determines the priority of a 1-hop downlink neighbour. Simulation results firmly
establish that the proposed protocol FP2 B produces high broadcast delivery ratio at muchlesser message cost, compared to other state-of-the-art broadcast algorithms.

Lecture 9 10 .mobile ad-hoc routing protocols
Mobile ad-hoc networks have frequent host and topology changes with no cellular infrastructure and require multi-hop wireless links for data transmission between nodes. Routing protocols must discover routes between nodes that may not be directly connected. Table-driven protocols like Destination Sequenced Distance Vector (DSDV) and Wireless Routing Protocol (WRP) maintain up-to-date routing tables through periodic broadcasts but generate significant control overhead. DSDV uses sequence numbers to distinguish stale routes and avoid loops while WRP maintains four tables for routing information.
Efectos de nodos ieee 802.15.4 zig bee
This document summarizes a study on the hidden node problem in IEEE 802.15.4/ZigBee wireless sensor networks. The study used an OPNET simulation model to evaluate the impact of hidden nodes on network performance. The results showed that as traffic load increased, goodput ratio and packet delivery time decreased while energy consumption per bit increased, due to more frequent packet collisions from hidden nodes. The hidden node problem caused significant packet loss and degraded network performance. Further work to address this problem by implementing RTS/CTS handshaking was proposed.
distance-vector-routing-3.pdf
The document discusses simulating distance vector routing and link state routing algorithms using the NS2 network simulator. It provides background on routing, describes distance vector and flooding routing algorithms, and includes the NS2 code used to simulate a simple network with four nodes using distance vector routing. The simulation establishes connections between nodes using TCP and UDP, introduces a route change, and monitors the routing table updates. The result is that the distance vector routing algorithm was successfully simulated.
A DELAY – CONSTRAINED IN MULTICAST ROUTING USING JIA ALGORITHM
The Distributed multicast routing protocol under delay constraints, is one of the software, which requires simultaneous transmission of message from a source to a group of destinations within specified time delay. For example. Video Conferencing system. Multicast routing is to find a routing tree which is routed from the source and contains all the destinations. The principle goal of multicast routing is to minimize the network cost. A tree with minimal overall cost is called a Steiner tree. Finding such tree is the principle of the NP complete.
Many inexpensive heuristic algorithms have been proposed for the Steiner tree problem. However, most of the proposed algorithms are centralized in nature. Centralized algorithm requires a central node to be responsible for computing the tree and this central node must have full knowledge about the global network. But, this is not practical in large networks. Therefore, existing algorithms suffer from the drawback such as heavy communication cost, long connection setup time and poor quality of produced routing trees. So far, a little work has been done on finding delay bounded Steiner tree in a distributed manner. An effort is made in this paper to this effect. The Study reveals that the drawbacks mentioned
above has been sufficiently reduced. This paper gives complete guidelines for authors submitting papers for the AIRCC Journals.
Gprs
This document summarizes a study on modeling GPRS session time distribution. The study group was asked to construct a model for simultaneous transmission of voice and data on mobile networks and determine equipment needs to provide a required quality of service. The summary develops:
1) A Markov chain model where voice calls have priority over data calls. The model accounts for variable voice, data arrival rates and data call sizes.
2) An initial model where each data call uses one channel. Balance equations are developed to calculate the stationary distribution.
3) Future work is outlined to model variable data call channel usage and develop numerical solutions to understand performance metrics like mean wait times.

Mutation Testing for Task-Oriented Chatbots
Conversational agents, or chatbots, are increasingly used to access all sorts of services using natural language. While open-domain chatbots - like ChatGPT - can converse on any topic, task-oriented chatbots - the focus of this paper - are designed for specific tasks, like booking a flight, obtaining customer support, or setting an appointment. Like any other software, task-oriented chatbots need to be properly tested, usually by defining and executing test scenarios (i.e., sequences of user-chatbot interactions). However, there is currently a lack of methods to quantify the completeness and strength of such test scenarios, which can lead to low-quality tests, and hence to buggy chatbots.
To fill this gap, we propose adapting mutation testing (MuT) for task-oriented chatbots. To this end, we introduce a set of mutation operators that emulate faults in chatbot designs, an architecture that enables MuT on chatbots built using heterogeneous technologies, and a practical realisation as an Eclipse plugin. Moreover, we evaluate the applicability, effectiveness and efficiency of our approach on open-source chatbots, with promising results.

"Choosing proper type of scaling", Olena Syrota
Imagine an IoT processing system that is already quite mature and production-ready and for which client coverage is growing and scaling and performance aspects are life and death questions. The system has Redis, MongoDB, and stream processing based on ksqldb. In this talk, firstly, we will analyze scaling approaches and then select the proper ones for our system.
Apps Break Data
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?
