A simple location propagation scheme for mobile sink in wireless sensor networks

The overhearing feature of wireless transmission has been widely employed for applications such as network time synchronization, malicious packet-modifying attacks detection, and reducing redundant transmissions in wireless sensor networks (WSNs). In this letter, we exploit the overhearing feature of wireless transmission to propagate the location information of a mobile sink to a source in WSNs, and to the best of our knowledge, this is the first design which exploit the overhearing feature for multi-hop information relay.
