Aisle Routing for Mobile Ad Hoc Networks

Mobility in ad hoc networks causes routes to break disrupting traffic flows and triggering additional routing overhead. We address this problem with a novel hybrid routing protocol, Aisle Routing. Aisle Routing introduces a route refresh mechanism to reactive source routing which proactively and adaptively refreshes routes through an aisle-like area and is designed so the route-control overhead is relatively small. This paper presents the Aisle Routing mechanism and describes how it can be integrated with existing reactive source routing protocols. Simulation results demonstrate that Aisle Routing has high packet delivery ratio and low delay in various mobility scenarios.
