In the recent times, the demands of Wireless Sensor Networks (WSN) increase the challenges in terms of scalability and energy efficiency.Research has made a significant progress recently in the area of key management for protecting data during communication plays a prominent role in wireless sensor networks.A good key management strategy ensures secure sharing of information among the group.To achieve data confidentiality, scalability and improving lifetime of the sensor, static and movable mobile sinks are deployed.Here, movable sinks are used to receive sensed data from the sensor where it is located.The static mobile sinks act as a trusted third party for computing and distributing keys between sensor nodes and the clusters.It is not necessary to chose new cluster head often because of trusted third party sink, it performs all the computations of cluster head.The energy is retained when computation is reduced in cluster head thereby increases the life time of the particular cluster.The experimental result shows that the lifetime of the network is improved and computational overhead reduced are proved.
