Abstract
To solve the location issue, in this paper, we proposed a Received Signal Strength for Directional Antenna (RSS-DA) scheme, it uses the mobile anchor nodes that already know the coordinates to join the Received Signal Strength (RSS) measurement in the data transmission. The number of beacons conforms to the terminated threshold in the sensor nodes, the estimated locations are used the RSS algorithm and the two-circle intersection algorithm for the calculations. Simulation results show that our proposed scheme of the sensor nodes are based in a mobile anchor node under RSS measurement, rather than the DIR localization scheme, to reduce the location error and achieve low energy consumption.
