Aspects of trusted routing communication in smart networks

In this paper, we have exploited the weight trusted routing (WTR) mechanism to detect and eliminate the malicious nodes involved during the routing path formation in smart-home environments where the routing between the communicating entities is performed through the mesh architecture. Further, to provide a secure communication against malicious behavior of nodes, the proposed mechanism uses Dijkstra’s shortest path routing algorithm in which the weights are deliberated using certain parameters such as nodedistance, packet-loss and trust value of each node which is computed using social impact theory optimizer. Moreover, we have presented the network performance trade-off caused by secure path formation with conventional method and have proposed the WTR mechanism for eliminating the potential issues such as packet-loss ratio, end-to-end delay and network throughput. The commercial simulator NS2 is used to simulate and compare the network metrics for both conventional as well as proposed approach and is validated with experimental results over end-to-end delay and message delivery ratio against reported literature.
