Proactive Secure Measures on Consolidated Query Multicast Protocol for Mobile Ad-hoc Networks

In a Mobile Ad-hoc NETwork (MANET) environment, multicast routing protocols are faced with the challenge of producing multi-hop routing under host mobility and bandwidth constraint. Premature work in MANET research has mainly focused on developing an efficient routing mechanism in such a highly dynamic and resource constrained network. At present, several efficient routing protocols have been proposed for MANETs. Still MANETs are vulnerable. The Consolidated Query Multicast Protocol (CQMP) protocol significantly reduces control overhead under the presence of multiple sources. This feature is a crucial contributing factor to the scalability of multicast routing for Mobile Ad hoc Networks. The routing attacks against Consolidated Query Multicast Protocol is eliminated by Trust based solution and Shamir Secret Key Sharing Scheme. It has been proved that the Shamir Secret Key Sharing Scheme is the best solution when compared with trust based solution which is based on the metrics like packet delivery ratio, control overhead and total overhead.
