This paper proposes a distributed adaptive routing protocol called Signal Stability based Adaptive Routing (SSA) for ad-hoc mobile networks. Unlike traditional routing schemes, SSA uses signal strength and location stability to dynamically adapt routes in a network with frequent link failures. The protocol allows mobile hosts to find and maintain stable routes without designated routers. SSA selects routes based on signal strength and location stability, which helps in choosing more stable links and reducing route maintenance. Simulations show that using signal strength reduces the number of route reconstructions, while location stability can be costly and is only useful in certain scenarios. The protocol includes two components: the Static Routing Protocol (SRP) and the Dynamic Routing Protocol (DRP), which work together to route packets in the network. The SRP handles routing table lookups, while the DRP maintains the routing table and interacts with other hosts. SSA also supports Mobile-IP for inter-operability. The protocol uses broadcast and flooding to propagate route search messages and handle route failures. The paper discusses the architecture, packet format, and protocol details of SSA, as well as simulation results showing the benefits and costs of using signal strength and location stability as route selection criteria. The results indicate that SSA performs well in highly dynamic environments, with fewer route reconstructions and better route stability. The paper also discusses related work and future research directions.This paper proposes a distributed adaptive routing protocol called Signal Stability based Adaptive Routing (SSA) for ad-hoc mobile networks.
