A Position-Based Random Key Pre-Distribution Scheme for Wireless Sensor Networks
Jiangtao Wang · Journal of Nanjing University of Posts and Telecommunications · 2007
Based on a random key pre-distribution scheme(RKPS), we develop a position-based random key pre-distribution scheme(PKPS) which uses position and prioritization to increase the probability of common keys between neighbor nodes,so that it can increase the probability of secure communication between nodes.The PKPS and its detailed performance evaluation are presented.It show that the communication cost,connectivity,and network resilience against node capture of sensor networks can be improved with the use of our proposed schemes.
