Secure Key Agreement with Rekeying Using FLSO Routing Protocol in Wireless Sensor Network

A challenge in wireless sensor network (WSN) is to design an energy efficient and secure network protocol because sensors are the wireless device with limited resources. To overcome the problem of insecure transmission in WSNs, efficient and light weight key agreement protocol (LARK) with rekeying is designed in which sensed data is carried out through the gateway node. In this paper, a novel construction is largely deliberated to abolish the security issues. The novel method called fuzzy C means cluster based light weight social spider optimization (FLSO) protocol for improving secure transmission with less energy consumption. In FLSO protocol, fuzzy C means clustering is used for grouping the nodes based on individual cluster’s membership and cluster head selection is associated with the lowest ID of the corresponding nodes. Next to clustering, secure transmission is done with the help of light weight key agreement protocol (LARK) with rekeying technique. In addition to the symmetric key, another one session key is generated to improve security using the Diffie Hellman cryptographic algorithm. Then the secure routing is done with the help of social spider algorithm. Finally, the simulation is performed on the platform of MATLAB simulator. In which results are taken in terms of memory, communication overhead, end to end delay, transmission delay, packet delivery ratio, authentication analysis, computational time and energy consumption. Results indicate that FLSO protocol provides efficient transmission by reducing energy consumption and providing security over the path of the transmission.
