Estimating link quality during multicast routing is vital for maximizing throughput in Wireless mesh networks. To efficiently forward data all mesh nodes must collaborate for computing path metric. If metric computation, propagation, and aggregation is based upon the assumption that all nodes are genuine then this will lead to haywire in adversarial networks where compromised nodes act maliciously. To counter the attacks of the compromised nodes earlier a combined measurement-based detection and accusation-based reaction techniques were implemented instead of aggressive path selection method. Both the attacks and defense were implemented using ODMRP protocol.
