Abstract

Recently, wireless detector networks (WSNs) haveBeendeployed for a good form of applications, includingmilitary sensing and pursuit, patient standing watching, trafficflow watching, wherever sensory devices typically move betweendifferent locations. Securing knowledge and communications needssuitable encoding key protocols. during this paper, we tend to propose acertificate less effective key management (CL-EKM) protocol forsecure communication in dynamic WSNs characterized by nodemobility. The CL-EKM supports economical key updates once anode leaves or joins a cluster and ensures forward and backwardkey secrecy. The protocol conjointly supports economical key revocationfor compromised nodes and minimizes the impact of a nodecompromise on the protection of alternative communication links. A security analysis of our theme shows that our protocol is effectivein defensive against varied attacks. We implement CL-EKMin Contiki OS and simulate it mistreatment Cooja machine to assess itstime, energy, communication, and memory performance.
