Security in IoT Mesh Networks Based on Trust Similarity

Internet of Things (IoT) Mesh networks are becoming very popular to enable IoT devices communicate without relying on dedicated PC services. implicitly uses mesh networks. connectivity cloud and edge computing is in vogue. A Wireless Network (WMN) a multi-hop distributed wireless network with routers clients. Data originating from clients forwarded destinations through routers. In networks, devices. The crucial security issue these the lack trusted third party for validation. However, trust between nodes required proper functioning network. WMNs particularly vulnerable as they rely upon cooperative forwarding. this research work, secure sustainable novel mechanism framework proposed. This identifies malicious improves nodes’ cooperation. proposed or model differentiates legitimate using direct indirect trust. Direct computed based packet-forwarding behavior node. have multi radios, so promiscuous mode may not work. new two-hop observe neighbors’ packet forwarding behavior. Indirect by aggregating recommendations weighted D-S theory, where weight similarity that correlates received different neighbors. Dynamic computation calculates overall several interactions. We present evaluations show effectiveness approach presence drop/modification attacks, bad-mouthing on-off collusion attacks ns-2 simulator.
