We present a detailed ns-2 [1] based simulation analysis on four of the prominent mobile ad hoc network routing protocols: Dynamic Source Routing (DSR) protocol [2], Associativity-Based Routing (ABR) protocol [3], FlowOriented Routing Protocol (FORP) [4] and the Routelifetime Assessment Based Routing (RABR) protocol [5]. The simulations were conducted with and without transmission power control...

The widespread deployment of mobile ad-hoc network (MANET) in the areas agriculture, military defence, weather forecasting and disaster control has necessitated implementation admission within a for guaranteed quality service (QoS). Admission organises traffic flows to ensure medium is fairly shared among various nodes network. Various algorithms have been proposed literature, using different m...

Secure data transfer in mobile ad hoc network (MANET) against malicious attacks is of immense importance. In this paper, we propose a new enhanced trust model for securing the MANET using trust-based scheme that uses both blind and referential trust. order to do this, relationship function has be integrated with dynamic source routing (DSR) protocol making more secure. We thoroughly analyze DSR...

On-demand routing protocols for mobile ad hoc networks utilize route caching in different forms in order to reduce the routing overheads as well as to improve the route discovery latency. For route caches to be effective, they need to adapt to frequent topology changes. Using an ondemand protocol called “Dynamic Source Routing” (DSR), we study the problem of keeping the caches up-to-date in dyn...

Mobile Ad hoc Network (MANET) is a self organizing wireless network for mobile devices. They do not need any fixed infrastructure to be configured which makes it more suitable to be used in environments that require on-the-fly setup. The present work discusses the challenging issues in MANET routing security. It presents improved DSR, a trust-based scheme for securing DSR routing protocol in MA...
