Relative speed quantification algorithm in AODV protocol

Abstract

Mobility is one of the basic features that define an ad hoc network, an asset that leaves the field free for the nodes to move. The most important aspect of this kind of network turns into a great disadvantage when it comes to commercial applications, take as an example: the automotive networks that allow communication between a groups of vehicles. The ad hoc on-demand distance vector (AODV) routing protocol, designed for mobile ad hoc networks, has two main functions. First, it enables route establishment between a source and a destination node by initiating a route discovery process. Second, it maintains the active routes, which means finding alternative routes in a case of a link failure and deleting routes when they are no longer desired. In a highly mobile network those are demanding tasks to be performed efficiently and accurately. In this paper, we focused in the first point to enhance the local decision of each node in the network by the quantification of the mobility of their neighbors especially their relative speeds. This metric can predict the movement of a node with respect to another node.
