Node Movement Control Based on Swarm Intelligence for a Mobile Medium Ad hoc Network

摘要

A Mobile Ad hoc Network (MANET) is a network of wireless mobile devices capable of communicating with one another without any reliance on a fixed infrastructure. A Mobile Medium Network is a set of mobile forwarding nodes functioning as relays for facilitating communication between the users of this Mobile Medium. The performance of the Mobile Medium depends on the Mobile Medium node density, distribution and movement. In the proposed new paradigm for node movement control based on swarm intelligence, the movement is determined based on whether the nodes are at the locations where data forwarding activity recently took place or not. Simulation results show that directing the nodes to the locations where the forwarding activity has recently happened significantly affects the delivery rates in the Mobile Medium networks. For some networks, with a few forwarding nodes initially dispersed in a large region, applying the swarm intelligence algorithm increases the delivery ratio by up to 50%.
