Mobile Sinks (MSs) are more significant in many Wireless Sensor Network (WSN) applications for well-organized data gathering and for unique and revoking compromised sensors. Mobile sinks are act as intermediate node. However, in sensor networks that make use of pairwise key establishment and authentication between sensor nodes and mobile sinks. In existing describes a three-tier general structure that permits the use of any pairwise key pre-distribution scheme. It requires two separate key pools, one for the mobile sink to entrance the network, and one for pairwise key establishment between the sensors. In addition it reduces the compensation caused by stationary access node replication attacks and improved the security performance of the proposed scheme of stationary access node replication attack.
