Probe packet based congestion free service discovery architecture for MANET

Abstract

MANETs (Mobile Ad-Hoc Network) are temporary networks composed of many autonomous nodes. Service discovery is the technology of finding services matching one's needs in the network, which is crucial to the usability of MANETs. In this work we inherit the property of swarm intelligence based service discovery architecture for MANET and prove the efficiency of our system based on 3 factors: Congestion avoidance/ load balancing, Energy efficiency and Secure Service Discovery model from the earlier system. Many service discovery protocols for MANETs have been proposed. But probe packet based Service Discovery model in MANET was not proposed earlier. So in this paper we propose an efficient probe packet based service discovery model in MANETProbe packets are packets generated for the sole purpose of identifying the discovery status of the MANET. It also determines the status of the network by the continuous polling mechanism. For energy efficiency we propose a zone routing based protocol. For secure service discovery model we propose a cluster based certificate authority model for making the service discovery model secure.
