Mobile Sink Optimization for Enhancing Data Delivery in Wireless Sensor Networks

As of late, the improvement of savvy sensors in certifiable applications has offered footing to the movement of Wireless Sensor Networks (WSNs). In WSNs, preserving sensors' energy is a challenging issue and certainly requires extreme attention as they are limited-powered nodes. Utilizing mobile sink based approaches has been proven to be effective in mitigating the aforementioned limitation. As far as the sensor nodes are concerned, keeping track of the sink location is one of the most challenging issues that is facing them. To address this concern, this article proposes an efficient clustering mobile sink-based approach for efficient data gathering. Particularly, the sink node moves in an Archimedes' spiral path with fixed speed without any location update broadcasting. The simulation results show significant improvements over which is quite pertinent in the literature in the perspective of network lifetime.
