Abstract: The benefits of utilising mobile sinks have been well accepted in various recent research papers. Mobile sinks are entities used for data collection from the sensor nodes in the network. Rather than placing the sink as static which may lead to an earlier demise of the network the mobile sinks in contrast are made to move along the network area. In this paper, we propose usage of multiple mobile sinks that changes their location accordingly to our proposed pathway. The pathway is engineered in a way so that it tries to distribute the load fairly among the sensor nodes in the network thereby intensively increasing the network lifetime. We have considered both constant and adaptive stopping time for sinks and have also formulated a linear programming model which optimises the sensor network lifetime.

Keywords: network lifetime; mobile sinks; adaptive stopping time; constant stopping time; predestined pathway; mobile networks; wireless sensor networks; WSNs; wireless networks; linear programming.
