Data Gathering in Wireless Sensor Networks with Uncontrolled Sink Mobility
Chien‐Fu Cheng, Heng Lee · 2016
In some applications, the moving path of the mobile sink is unpredictable. For sensors that have detected an event of interest, it is necessary to find the location of the mobile sink first before they can report the data. In this paper, we will discuss how source sensors can locate the constantly moving mobile sinks and send data packets through a less number of forwarding hop counts. The effectiveness of the proposed algorithm is verified by comparing with other data gathering via uncontrolled mobile sink algorithms. Moreover, our experimental results also confirm that the proposed algorithm can ensure that all source sensors can find the location of the mobile sink and reduce the average forwarding hop counts of data packets.
