Node localization to optimize the MPR selection in smart mobile communication

Nowadays, we are converging more and more towards smart environments like smart cars, drones, unmanned airplanes, internet of things and connected homes... These new gadgets are in need to communicate and interact with each other for their proper functioning. Due to their easy implementation, the mobile ad hoc networks constitute the fastest and the most efficient way to establish connection in smart environments. However, in proactive ad hoc routing protocol, like the Optimized Link State Routing, maintaining the topology increases the overhead and consumes a considerable energy power. In smart environments, some terminals are battery powered. Designing efficient communication protocols is crucial to decrease the interferences, to enhance the performance of the network and to reduce the consumption of energy. In this paper, we use the node localization in the context of OLSR to select dispersive Multi-Point Relays responsible of broadcasting the topology into the entire network. We divide the environment into several virtual zones. Then we try to elect forwarders at different partitions to cover the maximum surface area in order to reach the greater number of devices. The simulations show that our proposal reduces at certain extent, the amount of traffic overhead, improves the network capacity and lets more bandwidth for the smart environment's applications. © 2017 Association for Computing Machinery.
