A Secant Location Estimation Algorithm for Wireless Sensor Networks
نویسندگان
چکیده
The Location-based service on Wireless Sensor Networks, mainly depend on the Receiver Signal Strength (RSS) to measure the distance between the sender and receiver. The location unaware sensor nodes send beacon periodically which captured by anchor sensor nodes. However, the estimated distances may incur large error, and will risk the localization precision. A secant location estimation algorithm in wireless sensor network is proposed in this paper. The mobile anchor node can calculate the position for position unaware sensor nodes through the proposed location estimation scheme in the three-dimensional coordinate. The simulation results show the proposed algorithm is valid and effective.
