Enhancing Delay in MANET Using OLSR Protocol

Abstract

The performance of a Mobile Ad hoc Network (MANET) is closely related to the capability of the imple- mented routing protocol to adapt itself to unpredictable changes of topology network and link status. The Optimized Link State Routing (OLSR) protocol is a one key of the proactive routing protocols for MANETs. It is based on the multi-point relays (MPRs) technique to reach all nodes in the network with a limited num- ber of broadcasts. In this paper, we propose new versions of the original OLSR protocol based on a new mo- bility parameter, in the goal to enhance and adapt it in the presence of the mobility. For this objective we de- fine new three criterions for MPRs selection. The first criteria take for selection, just the mobility of nodes at one-hop. The two others criterions are based on both mobility of nodes at one-hop and two-hops.
