Resourceful and Secure Routing Protocol via Active Hierarchical Clustering Mechanisms for Wireless Sensor Network

Wireless sensor network combine information sensing, wireless communication, information processing in current years. Two major constraints related to wireless sensor networks are the dynamic variance of the network caused by capacity constraint of sensor nodes and uncertainties related to wireless links. Moreover, the problem in wireless sensor networks is the active variance in topology and provisioning of secure routing. These problems are attributed to the strict constraint of sensor nodes’ energy and the frequently variation of wireless channels qualities, which related with the nodes susceptible to energy failures and higher level of link prone from external interference. Certain works related to the hierarchical clustering did not address the problems related to the deployment model, efficiently on heterogeneous wireless sensor networks. Proposal of this work, introduces, Resourceful and Secure Routing Protocol (RSRP) for Wireless Sensor Networks based on Active Hierarchical Clustering mechanism (RSRP-AHC). Resource from the neighboring nodes serves as the dynamic information for the current network, with which sensor nodes make forwarding decisions based on energy aware and in a secure manner using RSRP. RSRP-AHC partition the nodes into clusters and select the Cluster Head (CH) based on the energy and Non Cluster Head (NCH) nodes join in the specific CH based on SNR values. Error removal during hierarchical cluster routing is achieved to avoid end to end error occurrence in network. Security is derived by isolating the malicious nodes using resourceful based secure routing pattern analysis. The experimental performance of RSRP-AHC mechanism is evaluated against Location-Based Pair wise Key Pre distribution model to attain packet delivery ratio, security level, and improved error recovery rate.
