Wireless sensor nodes have restricted computational resources, and are always deployed in a harsh, unattended or hostile environment. Therefore, network security represents a challenging task. This work presents a public-key based pre-distribution scheme with time-position nodes for simultaneous exchange of secure keys. The proposed defend attack and key management mechanism for sensor network applications can successfully handle sink mobility and can continually deliver data to neighboring nodes and sinks. Simulation results indicate that the proposed mechanism can reduce energy consumption and extend the average network lifetime by about 25%.
