Recent studies have shown that utilizing a Mobile Sink (MS) to harvest and carry data from a Wireless Sensor Network (WSN) can enhance network operations and increase the network lifetime. Since a significant portion of sensor nodes’ energy is consumed for data transmission to MS, the specific trajectory has a profound influence on the lifetime of WSN. In this paper, we study the problem of controlling sink mobility in event-driven applications to achieve maximum network lifetime. In these applications, MS with limited velocity has to harvest the captured data of events from a group of sensor nodes in a specific time as a reporting time slot. We show that this problem is NPhard, and then we propose a convex optimization model inspired by the Support Vector Regression technique to determine an optimal trajectory of MS without considering predefined structures like a virtual grid or rendezvous points. The effectiveness of our approach is validated via the extensive number of simulation runs and comparison with other algorithms. |
