Topology Management in Self- Adaptive MANET: A Distributed Approach

This paper proposes a distributed algorithm for the maintenance of topology of a network in a MANET (Mobile Ad-hoc Network). In this algorithm, it is assumed that every node possesses GPS receiver. Nodes receive the position and velocity information of their neighbors at the end of each beacon interval through GPS. Next, these nodes check whether a certain condition is violated or not. A node changes its velocity if the condition is not satisfied; otherwise it tries to keep the velocity constant. In this way each node modifies its velocity for the next beacon interval. The simulation run of the algorithm is carried out on a number of synthetically generated network scenarios and results thus obtained show the effectiveness of the proposed algorithm.
