Abstract :
In the paper, a new range-boundary aware mobility-assisted localization(RAML) scheme is presented to make mobile sink identify the location of sensor nodes which are deployed in a random mode within a certain geographical area. Not like other localization techniques, the presented localization scheme works without any additional hardware and achieves better efficiency through broadcasting special beacon messages for single hop acknowledgement. Sensor node location is calculated after two specific time-stamps are obtained, one time-stamp once the sink just enters into the communication range of the sensor node and another one once it leaves. We present detailed description of RAML as well as its implementation approach in real-world and simulation environments, respectively. Simulation in ns-2 is conducted to verify the efficiency and correctness of RAML.
