Application of Random Key Predistribution to the Secure Tracking in Wireless Sensor Network

To enhancing the wireless sensor network's security in target tracking and locating application,a tracking cluster based mobile cluster distributed group rekeying protocol(MCDGR) was proposed.Based on the given sensitivity,sensors can locate the moving object in the monitored area and form a tracking cluster around it.This tracking cluster can follow the target logically,process data on the target and report to the sink node,and thus achieve the tracking function.Based on the multi-path reinforcement scheme,q-composition scheme and one-way cryptographic hash function,random key predistribution algorithm(RKP) was introduced to guarantee a high accuracy and security and a low energy consumption on the same time in large-scale sensor network.
