Mobility Metrics to Enable Adaptive Routing in MANET

The performance of MANET routing protocol depends on the network conditions, which includes mobility, congestion and transmission condition. In this paper, we discuss the impact of mobility on the performance of the routing protocols, using three different mobility models. We further look into different parameters which change with the mobility from the point of view of individual nodes, showing that nodes experience different levels of mobility at different points of time. Finally we propose that the number of link breakages observed by a node can be used as a mobility metric so that each individual node can adjust its routing behavior based on the environment around it to improve the overall routing protocol performance
