Improved key management scheme for wireless sensor networks using hexagon cells and deployment knowledge
基于地理位置的蜂窝状密钥管理方案

WSN is consisted of low-computation,low-storage,low-communication ability micro nodes,key management acts as the basic manner to assure security and authentication of information transported by nodes in WSN.An improved scheme making use of deploy knowledge based on random key predistribution had been made,adopting hexagon cells.The new scheme can use less memory,perform better with the same number of compromised nodes,and suit for large-scale networks.
