Mobility quantification for MultiPoint Relays selection algorithm in Mobile Ad hoc Networks

In Mobile Ad hoc Networks (MANETs), with Optimized Link State Routing Protocol (OLSR) the mobility concept is an essential element which can result in the evolution of network performances. In this paper, the main objective is to develop an algorithm to improve the MultiPoint Relay (MPR) selection process in such networks. This algorithm is based on the Mobility Rate (MR) which in turn is relied on the relative velocity of nodes. Additionally, in this algorithm, each node keeps a mobility rate record of other nodes. Moreover, this mobility value will be exchanged between nodes using OLSR messages (HELLO and Topology control (TC)). Furthermore, this value will be used as a criterion when a node chooses their MPR set. In addition, the simulation results using Network Simulator 3 (NS3) have shown that the mobility concept could improve network performances in terms of the throughput, packet received, packet loss, packet delivery ratio and packet forwarded. Moreover, and through this paper the proposed algorithm can be used as a functional mobility mechanism to improve network performances in MANETs.
