Abstract
WSNs (Wireless Sensor Networks) are becoming more and more capable with each passing day. Widespread usage of WSNs is helping mitigate many dangers. Protecting these networks from risks need proper security measures. This paper offered a security strategy that makes use of IEKC (Improved Elliptic Key Cryptography). Data encryption and decryption are accomplished via IKEC. A major feature of this technique is that node's source codes maintain Private Keys which protect other keys in non-volatile memories. The suggested technique prevents replay, DoS and Sybil attacks. In this node, cluster chiefs are chosen using CSO (Chicken Swarm Optimization) and nodes are organised according to network size. According to the findings of the simulation, this security mechanism effectively counters different attacks with fewer resources, and it also significantly strengthens the network's resistance to node capture. Results from experiments show that the suggested model is effective regarding PDR (packet delivery ratio), end-to-end latency, throughputs, and energy consumptions.
