Abstract :-
Multihop wireless networks rely on node cooperation to provide multicast services. The multihop communication offers
increased coverage for such services but also makes them more vulnerable to insider (or Byzantine) attacks coming fromcompromised nodes that behave arbitrarily to disrupt the network. In this work, we identify vulnerabilities of on-demand multicast
routing protocols for multihop wireless networks and discuss the challenges encountered in designing mechanisms to defend againstthem. We propose BSMR, a novel secure multicast routing protocol designed to withstand insider attacks from colluding adversaries.
Our protocol is a software-based solution and does not require additional or specialized hardware. We present simulation results thatdemonstrate that BSMR effectively mitigates the identified attacks.
