To obtain secured communication in Wireless Sensor Systems (WSS), a secret shared keys is created between sensor nodes and neighboring nodes.The shortest path is found by using Dijkstra's Algorithm.By the use of this algorithm the energy consumption will be reduced.In this paper, location based key for WSS, with proper attention over the insider attacks is proposed.After reviewing and analysing present key management systems, Location Based Key (LBK) management is selected.To deal with the communication interference problem in LBK, a new key revision technique that involves grid-based location information is devised.Furthermore, a key renew and cancellation processes is constructed to withstand inside attackers in OFDM antenna.For analysis, a accurate simulation is conducted and proved that can increases connectivity and decreases the compromise ratio when the least possible number of common keys needed for key establishment is high.
