Significant research efforts have been made towards increasing the survivability of MANET either by developing secure routing algorithms or by improving the robustness of MAC...

    Mobile Agent as an Approach to Improve QoS in Vehicular Ad Hoc Network

    Vehicular traffic is a foremost problem in modern cities. Huge amount of time and resources are wasted while traveling due to traffic congestion. With the introduction of sophisticated traffic management systems, such as those incorporating dynamic traffic assignments, more stringent demands are being placed upon the available real time traffic...

    Analytical Study the Performance Evaluation of Mobile Ad Hoc Networks Using AODV Protocol

    The Mobile Ad hoc NETworks (MANETs) have been communicating over wireless mesh channels and support multihop networks. Every node in the MANET is free to move independently in any direction. MANET is a kind of wireless mesh network which operates in Link Layer (LL) of Ad hoc networks. The current...

    A Load Aware Routing Mechanism for Improving Energy Efficiency in Mobile Ad Hoc Networks

    Integration of Load Balancing mechanisms into routing protocols has elicited significant interest to alleviate congestion and improve the performance of on-demand routing protocols. For the sustained network functionality, load balancing mechanisms need to compute energy efficient paths with lesser traffic. Further severe degradation of network performance is observed due to...

    Analysis of K-Connected MANETs for QoS Multicasting Using EDMSTs Based on Connectivity Index

    The survivability of the network is closely related to the connectivity of the network. For many network applications such as a sensor network/ad hoc network for battlefield monitoring or wild fire tracking etc., survivability is one of most important requirements, and therefore a number of related problems are proposed. In...

    Scenario Based Performance Analysis of Variants of TCP Using NS2 - Simulator

    The increasing demands and requirements for wireless communication systems especially in settings where access to wired infrastructure is not possible like natural disasters, conferences and military settings have led to the need for a better understanding of fundamental issues in TCP optimization in MANETS. TCP primarily designed for wired networks,...
