The Research On Energy-efficient And Compromise-resistant Pairwise Key Establishment Algorithm For Sensor Networks

Wireless sensor networks is a kind of network in which lots of sensors interrelate, process and transmit information with each other through wireless communications. External uncertainty environments often require hundreds of sensors shall be deploymented to work together, so research on the large-scale sensor networks is gradually aroused widespread interest and considered to be a challenging research topic of this century. Currently, the academic research mainly concentrated in the sensor clustering algorithm, communications routing protocols, network coverage and sensor sensor data fusion technology.From the aspect of security and prolonging lifecycle of sensor networks, this paper analyzed the merits and drawbacks of existing key management schemes. In order to guarantee the stability of network topology structure as long as possible and utilize the energy of sensor networks in equilibrium, this paper introduced a new clustering model and Clustered-Based Adaptive On-demand Weighted clustering algorithm(CBAOW), and furthermore, a new pairwise key establishment algorithm (EE-DPKEA) was proposed, Compared to conventional works it outstands in performance.The contents of this article are as following:(1) Introduced CBAOW algorithm, and proposed EE-DPKEA algorihm.(2) Simulated a platform by Delphi language and SQLSERVER to demensrate the sensor distribution and pairwise key establishment among senser nodes.(3) Evaluated the performance of EE-DPKEA algorihm.
