Weight based DSR for Mobile Ad Hoc Networks

Abstract

Routing in ad hoc network is a great problematic, since a good routing protocol must ensure fast and efficient packet forwarding, which isn't evident in ad hoc networks. In literature there exists lot of routing protocols however they don't include all the aspects of ad hoc networks as mobility, device and medium constraints which make these protocols not efficient for some configuration and categories of ad hoc networks. Thus in this paper we propose an improvement of Dynamic Source Routing Protocol DSR in order to include some of the aspects of ad hoc networks as mobility and energy by proposing a new metric to evaluate route based on intermediate nodes weight computed by combining the stability an the battery power of nodes to choose the most stable and powered nodes for packet forwarding. The paper is organized into five parts, in the first ones we give an overview of ad hoc networks and routing protocols; and a brief presentation of DSR. However the rest of parts are consecrated for our proposed improvement for DSR and simulation results of Weight Based Dynamic Source Routing Protocol WDBSR finishing the paper by a conclusion and future extension of this work.
