Secure Efficient Geographic Multicast Protocol For Mobile AdHoc Networks
Journal Title: International Journal of P2P Network Trends and Technology(IJPTT) - Year 2013, Vol 3, Issue 1
Abstract
A mobile ad-hoc network (MANET) is composed of mobile nodes without any infrastructure. So that Ad hoc networks are mainly used in emergency situations where no infrastructure is available, for e.g. military battlefields, disaster mitigation, emergency search, rescue sites, classrooms and conventions, where participants share information dynamically using their mobile devices. These applications lend themselves well to multicast operations. In addition, within a wireless medium, it is even more crucial to reduce the transmission overhead and power consumption. Multicasting can improve the efficiency of the wireless link when sending multiple copies of messages by exploiting the inherent broadcast property of wireless transmission. Scalability is important issue in term of group size and network size while designing multicast protocol. In addition security is an essential requirement in MANET environments. Compared to Wired networks, MANETs are more vulnerable to security attacks due to the lack of a trusted centralized authority, easy eavesdropping, limited power and bandwidth, and dynamic network topology. Efficient Geographic Multicasting Protocol (EGMP) came into existence to implement group communication in MANET. Efficient Geographic Multicast Protocol (EGMP) uses a virtual-zone-based structure to implement scalable and efficient group membership scheme. The efficiency and scalability of the protocol was already tested but security aspect is not considered. To further improve the efficiency of the protocol, we propose a Secure Efficient Geographic Multicast Protocol (SEGMP).In this paper we study comparative analysis of simple mesh topology using ADOV, EGMP and SEGMP and test average delay, throughput, packet delivery ratio, energy
