BSMR: Byzantine-Resilient Secure Multicast Routing In Multi-Hop Wireless Networks

Multi-hop wireless networks rely on node cooperation to provide unicast and multicast services. The multi-hop communication offers increased coverage for such services, but also makes them more vulnerable to insider (orByzantine) attacks coming from compromised nodes that behave arbitrarily to disrupt the network.In this work we identify vulnerabilities of on-demand multicast routing protocols for multi-hop wirelessnetworks and discuss the challenges encountered in designing mechanisms to defend against them. We proposeBSMR, a novel secure multicast routing protocol that withstands insider attacks from colluding adversaries. Ourprotocol is a software-based solution and does not require additional or specialized hardware. We present simulationresults which demonstrate that BSMR effectively mitigates the identified attacks.
