A Key Re-Distribution and Authentication Based Technique for Secured Communication in Clustered Wireless Sensor Networks With Node Mobility
Due to application of WSN in mission critical areas, secured message communication is very important. The authors have attempted to present a methodology that ensures secured communication among nodes in a hierarchical Cluster Based WSN. The scheme works when member sensor nodes move from one Cluster Head (CH) to another. The proposed scheme is based on Key Redistribution during node mobility and development of an Authentication Model to check whether the new node in a cluster is an intruder. They have carried out extensive simulation experiments, which demonstrate the efficacy of the proposed scheme. The experiments suggest that the number of message transmission increases linearly with the number of mobile nodes during key-redistribution when a node moves from one CH to another.
