On Metrics for Mobility Oriented Self Adaptive Protocols

Mobile networks performance may be enhanced by cross-layer mechanisms. Some of those mechanisms are based on mobility metrics. For example, the establishment of a route by choosing less mobile node could improve the routing protocol. In this paper, we study the ability of mobility metrics to reflect the mobility. The proposed approach evaluates the ability of a metric from its influence over routing protocols. Three routing protocols are considered: AODV, DSR and OLSR. The studied mobility metrics are frequency of link state changes (LC), link connectivity duration (LD) and link stability metric (LS). The metrics are evaluated by simulation, firstly in a general case then in a scenario case.
