Implementation of a Topology Control Algorithm for Mobile Ad hoc Networks Using Pursue Mobility Model

Abstract

In this paper we have presented a physical implementation of a topology control algorithm for MANETs. Mobile nodes follow the characteristics of the Pursue Mobility model. There is no need to change routing table as connectivity of the network is maintained all through. Every node in the network is free to travel with its own velocity. Individual node can take the decision on its own to change the velocity for maintaining the connectivity with the node being pursued (target node). Each mobile node is equipped with a transceiver and a GPS receiver. Target node transmits its velocity and coordinate information periodically to all pursuer mobile nodes in a network. The pursuer nodes, after receiving this information from the target node, will modify its own velocity, if required, to maintain the topology. Results obtained through the experimentation with the prototype developed, demonstrate that the connectivity and hence the topology of the network is maintained always.
