Abstract:

Sensor location is most important information for application in wireless sensor networks. Every sensor node transmits the information through the locations. If the sensor launched in un friendly environment it will meet various attacks, and the sensor’s location is not trustable. The previous scheme requires group based deployment. It would not be use in the low-cost sensor networks. Here we introduce a novel Lightweight location verification algorithm. It contains two sub algorithms namely 

1. GREEDY FILTERING USING MATRIX(GFM)

 2.GREEDY FILTERING USING TRUSTABILITY-INDICATOR(GFT)
