—In the past few years there has been increasing research interest in service discovery protocols for Mobile Ad Hoc Networks (MANET). The most promising approaches so far address energy efficiency by merging the service discovery process with the routing process. Actually the service information is piggybacked into routing messages, so that a node is simultaneously informed of available services and of routes towards the corresponding service providers. This cross layering leads to improved adaptation to the network conditions and at the same time to significant energy savings. Those savings are infeasible if the two processes are implemented separately, because then each one would have to use its own messages and create additional (if not) redundant network overhead. In this paper we propose such a hybrid adaptive protocol for energy consumption-avert users. This protocol, named AVERT, is based on the Independent Zone Routing framework (IZR) and has the ability to allow each node to...
