The Ad hoc network is a part of the IoT environment, including several types of networks like MANET. It uses different categories of routing protocol, but the OLSR routing protocol is the best one for MANET. The mobility concept has an impact on the evolution of network performances. In the OLSR routing protocol, this mobility influences on the choice of the MultiPoint Relay (MPR). In this paper, the main objective is to develop an algorithm enhancing MPR selection process in such networks. This algorithm based on Average Spatial Dependency metric “ASD” linked to the average Relative Speed “RS” and the average Relative Acceleration “RA”. Each node shares these values with its neighbors using the messages of OLSR routing protocol (Hello and TC messages). Furthermore, if the nodes have equal reachability, the highest ASD value will be selected as a criterion of the choice of their MPR set. In the simulation, we have applicated the Manhattan mobility model in the MANET network, and we have used the NS3 simulator. The results of this simulation have shown that the mobility concept could change network performances in terms of packet loss, end-to-end delay, and Throughput. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2020.
