A Light-Weight Service Discovery Protocol for Ad Hoc Networks

Free registration required

Executive Summary

In mobile ad hoc networks devices do not rely on a fixed infrastructure and thus have to be self-organizing. This gives rise to various challenges to network applications. Existing service discovery protocols fall short of accommodating the complexities of the ad-hoc environment. However, the performance of distributed service discovery architectures that rely on a virtual backbone for locating and registering available services appeared very promising in terms of average delay but in terms of message overhead, are the most heavy-weight. In this paper, the authors propose a very light-weight, robust and reliable model for service discovery in wireless and mobile networks by taking into account the limited resources to which are subjected the mobile units.
