A Middleware Support for Location-Based Service Discovery and Invocation in Disconnected MANETs

Disconnected MANETs show a changing topology and a fragmentation in distinct communication islands. In such networks, service discovery and invocation rely preferably on protocols that can support connectivity disruptions such as opportunistic protocols based on the store, carry, and forward principle. In this paper we present a middleware platform for geolocated services in disconnected MANETs. We detail in particular the location methods we used, the facilities for service discovery, selection, and invocation, and the undelying opportunistic communication protocol. Lastly, simulation results show the advantage of geolocation for service provision in such networks.
