Abstract

Efficient service discovery mechanism is a crucial feature for the usability of a wireless ad-hoc network. A wireless ad-hoc network is a temporal network formed by a collection of wireless mobile nodes without the aid of any existing network infrastructure or centralized administration. We propose an efficient service discovery mechanism using link/node non-disjoint multi-path source routing protocol for pervasive environments. Multi-path routing techniques can operate more quickly and adaptively when route failure occurs. Cross-layer technique can reduce the number of messages because nodes perform to search a service and to find the route at once. Our scheme has advantages of not only multi-path routing protocol but also cross-layer service discovery. This scheme provides faster route recovery and lower route maintenance overhead by limiting the number of multiple routing paths and by maintaining link/node non-disjoint multi-path.
