摘要

Signal in open environment is easy to be attacked and traditional RSSI location technology produces errors in application of wireless sensor networks. By analyzing the location model of RSSI, this paper proposes a new encryption modulation algorithm: RSSI-AM, which is different from many existing approaches. The location algorithm has the following advantages: strong security, simple calculation, powerful anti-interference ability and no hardware expansion required. Besides, the simulation experiment shows the location precision of ranging method based on RSSI-AM has obvious improvement compared with traditional algorithm. It can be used in the environment of wireless sensor network nodes with low cost and performance of hardware.
