Signal Stability based Adaptive Routing (SSA) for Ad-Hoc Mobile Networks

Abstract

Unlike static networks, ad-hoc networks have no spatial hierarchy and suffer from frequent link failures which prevent mobile hosts from using traditional routing schemes. Under these conditions, mobile hosts must find routes to destinations without the use of designated routers and also must dynamically adapt the routes to the current link conditions. This paper proposes a distributed adaptive routing protocol for finding and maintaining stable routes based on signal strength and location stability in an ad-hoc network and presents an architecture for its implementation.
