Increasing stability is one of the main objectives in designing routing protocols for Mobile Ad-Hoc Network (MANETS). Various research schemes have been addressed to this challenge and to support it. In fact, some papers have considered modifications to MPRs selection mechanism in OLSR. In this paper, the author proposes a new mechanism to elect stable and sustainable nodes relay between all nodes in MANETs. In this mechanism, a mobility function is used as the main selection criterion based on the calculation of the spatial relation of a node relative to its neighbor. This mechanism is applied in OLSR protocol to choose stable and supportable MPRs nodes. This mechanism significantly finds more stable MPRs and it promises QoS metrics such as lost packets and delay. Simulation results reveals a significant performance gains and it motivates further examinations to develop the mechanism in order to improve the routing protocol requirements. Performances are evaluated based on Random Waypoint model and network simulator ns3.

The main idea behind the routing protocols based on multi-hop is to find the required path from the source node to the destination. Since those protocols do not consider the node mobility in their mechanism, we propose to enhance the routing protocols benefiting from localization node and predict the time needed for neighbors to go out of range for a node to increase the robustness of the protocols with the mobility. Firstly, we propose an efficient scheme to predict the time needed for the node to quite the neighbor range. Secondly, we conduct a set of simulations to compare the performance of our proposal against OLSR standard.
