A Key Establish Scheme for Wireless Sensor Networks Based onNode Location
MA Zi-heng · Journal of Qinghai Normal University · 2010
Based on key pre-distribution scheme in wireless sensor networks(WSN),the paper develops a location-based random key pre-distribution scheme(LRKPS).It analyzes some weaknesses of random key pre-distribution scheme,also points out disadvantage of the correction presented in some journals.Based on node location and key correlation,LRKPS can be substantially improved performance in probability of shared key,connectivity of network,and network resilience against node capture of sensor networks.The simulation has validated the effectiveness of the new scheme by comparing with random key pre-distribution scheme.
