Repetitious Key Negotiations in Wireless Sensor Networks
Wen Zhang · Jisuanji gongcheng · 2009
Key negotiation needs several times in Wireless Sensor Networks(WSN) because of high loss rate.In order to research the effectiveness of repetitious key negotiations on heightening secure connectivity,it proposes two metrics named the weighing secure connectivity and Cost Performance Ratio(CPR),and it processes the simulation experiments on TOSSIM platform.CPR becomes lower and lower as the number of key negotiations increases.Simulation results and analysis show that 3～4 times repetitious key negotiations are more suitable for high secure connectivity.
