Lifespan Enhanced Energy Efficient Cluster Formation and Trusted Multipath Data Transmission for Packet Forwarding in Wireless Sensor Network

Due to unwant overhead in security process of WSNs, the time consumption of each node is very high from authentication, key generation and key distribution phases and hence every data packet experiences the same latency. The efficiency of exchanging the secret key degrades rapidly as a function of external signal interference power and limits its resilience against active attackers. Increases the latency in the network since Secret Key (SK) value is refreshed for every session, to increase the security strength of the data communicated, the overhead utilization in the network increases rapidly. In Reliable Anonymous Secure Packet forwarding (RASP) scheme uses a total of 44 bytes’ packet size, the size of authentication message is 20 bytes and 20 bytes for data being transmitted (160 bits). Hence the number of transmission is increased which in turn increases the control overhead and traffic at the network and demands for secret key during each transmission. To overcome these problems, we propose multipath routing protocol based on the clustering algorithm. Particle Swarm Optimization (PSO), cluster formation is carried out to optimize intra-cluster and sinks distance of the entire cluster heads (CHs), it is used to reduce the energy consumption in WSNs. For an enhancement of network life time and security, we consider the trust values of each node in the cluster formation and head selection process. The trust values are calculated from the trust inference model (i.e. dolphin echolocation algorithm). Finally, the trusted clustering model is combined with the standard multipath routing protocol (i.e. AOMDV) used to analyze the performance and security issues. The simulated result shows that the proposed scheme is perform better than RASP scheme. The network lifetime of proposed work is increased by 10%, 8%, and 15% than RASP scheme. The delay of proposed work is decreased by 5%, 3%, and 5% than RASP scheme. The energy consumption of proposed work is decreased by 10%, 5%, and 4% than RASP scheme. The delivery ratio of proposed work is decreased by 5%, 5%, and 5% than RASP scheme.
