A Service Discovery Protocol with Maximal Area Disjoint Paths for Mobile Ad Hoc Networks

摘要

Service discovery is a basic requirement for mobile ad hoc networks to provide service efficiently with dynamically changing network topology. In this paper, we propose a service discovery protocol with maximal area disjoint path (SDMAD) for mobile ad hoc networks. The goal of SDMAD is to exploit multiple servers simultaneously and do parallel delivery. One key feature of SDMAD is that there is no contention between the multiple paths discovered by it. Moreover, SDMAD considers service discovery and routing jointly to reduce control overhead. Extensive simulations show that with SDMAD the performance of service delivery is greatly improved over that with other service discovery protocols.
