A Secure Core-Assisted Multicast Routing Protocol in Mobile Ad-Hoc Network

In this paper, an Efficient and Reliable Core-Assisted Multicast Routing Protocol (ERASCA) is secured from a malicious/selfish receiver attack and fabrication attack. In former the ERASCA is secured from malicious/selfish attack through battery estimation technique. With battery estimation technique, a malicious or selfish receiver shows high or low battery capacity for the purpose to become a core or evade to become a core node. The malicious or selfish receiver is detected and removed from the mesh by comparing estimated value and claimed value. Similarly, malicious nodes may alter data or inject spoofed messages in the network. In addition, a packet authentication process is also used to prevent nodes from tampering with data and generating spoofed messages. At the end of paper, Network Simulator-2 is used to observe the performance of protocol and evaluate the conclusion based on results.
