Secure Efficient Geographic Multicast Protocol for Mobile AdHoc Networks
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.
