Abstract:
Optimized Link State Routing (OLSR) is a proactive protocol designed to operate inMobile Ad Hoc Networks (MANET). In this protocol, the topology is based on MultiPoint Relay (MPR) Mechanism. However, the loss of one or many MPRs caused by their movement affects the link state of the network. Therefore, the contribution of this paper is to keep the network links between the nodes and MPRs in stable state as long as possible. It was done by calculating a new parameter named Average Age of Death which estimates the life duration ofMPRs. The experimental results illustrate that this parameter is affected by the environment (speed of node, network density and others). This result provides to use this parameter as a new mobility metric that can be used in the MPR sets Calculation.
