Link Stability is a crucial factor in designing routing protocols for Mobile networks. Most of the routing strategies that supports for link stability are designed to meet some QoS constraints. Dynamic nature of nodes and the presence of stale information make this very difficult. In this paper, the authors present a performance evaluation of some of the existing link stability based routing mechanisms and proposes a routing protocol called Link Stability Aware Routing (LSAR) protocol that determines a path with maximum stability. The mechanism uses the concept of both Remaining Link Lifetime and Stability metrics to measure the stability of links in the network. The route with its links having maximum link ages contributes higher Remaining Link Lifetime and thereby considerable path stability.
