Hybrid Extend Particle Swarm Optimization (EPSO) model for Enhancing the performance of MANET Routing Protocols

The routing protocols in MANETs are designed to provide efficient and reliable communication in a highly dynamic and resource-constrained environment. It is very efficient and requires low computational and memory resources compared to most routing protocols. Therefore, mobility and the number of nodes significantly impact the performance and reliability of routing protocols. This paper proposes a hybrid extended particle swarm optimization (EPSO) model to improve the performance of MANET routing protocols. It determines the optimal mobility and the number of hubs and nodes that satisfy the best possible version of MANET. MANET requires a robust routing algorithm that can adapt to a network that arbitrarily changes its topology at any time. The proposed model in the NS2 simulator proves the model's validity in improving the performance of MANET. The proposed model sets the general parameters of routing protocols and achieves high performance with fewer discarded packets and low delay when sending and receiving over MANET. The MANET sent 167 packets in the proposed model, and the number of discarded packets was less than 1%.

Multipath Optimized Link State Routing Protocol with Multi-Variant Deficit Round Robin

Optimized Link State Routing Protocol (OLSR) is extended by multipath allocation of bandwidths which is known to be Multipath Optimized Link State Routing Protocol (MP-OLSR). OLSR is proactive that widely used in communication of dense and complex network traffic as it is more stable and easily adaptive. MP-OLSR takes multipath Dijkstra’s algorithm which is used for better performance of MANET routing protocols by considering scalability, route recovery and loop breakage detection in communication network traffic. MP-OLSR protocols with improvements have been proposed such as implementation of Round Robin, weighted Round Robin (WRR). But these protocols lack multi-variant adaptability to network path conditions. So, in order to overcome such drawbacks, an enhanced MP-OLSR-Deficit Round Robin (DRR) combined with QoS metrics delay, and mobility speed of nodes is proposed. To implement proposed system, network simulator NS2 is presented along with result showing packet delivery ratio, end-to-end delay and jitter.

Performance Evaluation of Diverse MANET Routing Protocols A Review

MANET is infrastructure less, decentralized multi-hop network where the mobile nodes are free to move randomly, these mean the network topology dynamic, the performance evaluation is major challenges in ad hoc network. Performance evaluation refers to evaluate the performance of MANET routing protocols, there are various performance metrics are used to improve the performance of MANET routing protocols. Performance are evaluated in case of change in traffic, number of nodes, mobility and pause time etc. performance is measured in term of packet delivery ratio, routing load, average jittering and throughput. In this paper, we review on the various research papers related to the performance evaluation of various routing protocols and performance comparison of routing protocols in MANET, we also provide the overview of MANET routing protocols such as: AODV, DSDV, DSR and ZRP. Keyword: MANET, Performance Evaluation, AODV, DSR, ZRP.

Venue-based Mobility Models: Evaluation of MANET Routing Protocols

is infrastructure less network consisting of wireless nodes acting either as a host or a routing node. A number of simulation studies have been carried out to evaluate the performance of MANET routing protocols. In typical simulations, nodes move at speeds between the broad range of 1 - 30 m/s, whereas in a real life setting, the movement speed of nodes at a particular venue may be confined to a narrower range depending on the nature of the venue. This paper analyzes the performance of routing protocols, on the basis of four venue based mobility models. These models are Fast Car Model (FCM), Slow Car Model (SCM), Human Run Model (HRM) and Human Walk Model (HWM). Four routing protocols namely AODV, DSDV, DSR and TORA are compared in this paper. The simulation results show that DSDV has low end-to-end delay, whereas TORA has high overhead as speed is increased.

Mobility Contrast Effect on Environment in Manet as Mobility Model

Manet is a type of ad-hoc network without any infrastructure and connects mobile nodes through wireless channels. It gives environment in which nodes can be connected dynamically as they enter the area. The area can be any place where nodes can move uniformly or randomly like disaster hitting places, shopping malls, airport, station, campus, business meeting, and temple etc. Depending on the terrene, and physical infrastructure and environment that may cause obstacle in the movement of nodes in the given area, the mobility pattern of nodes is different. These involve the mobility environment as major factor for mobile nodes while sharing information in mobile ad-hoc network. The characteristics of mobility of nodes in Manet are application based and have significant impact on the performance of routing protocols. While studying the performance of MANET routing protocols, environment parameter as mobility is important and can be considered remarkably so that realistic scenario can be constructed for the accurate analysis of performance of routing protocols.

Traffic Pattern based performance comparison of Reactive and Proactive protocols of Mobile Ad-hoc Networks

The primary objective of this research work is to study and investigate the performance measures of Reactive protocols (AODV, TORA) and Proactive protocols (DSDV) routing protocols of MANET using TCP & CBR based traffic models. In this paper we will simulate the environment used for analyzing, evaluating and implementing AODV, DSDV and TORA routing protocols in MANET, to analyze the performance of above said protocols based on Packet Delivery Ratio, Average End-to-End Delay and Throughput. We will investigate the effect of change in number of nodes on MANET routing protocols. Here, we will analyze and compare the performance of MANET routing protocols based on both CBR and TCP based traffic patterns. We have used the NS-2 simulator for performing various simulations and used awk scripts for analyzing the results.
