Recently, there has been a rapid growth in the wireless communication technique. Mobile sinks can be mounted upon urban vehicles with fixed trajectories provide the ideal infrastructure to effectively retrieve sensory data from such isolated WSN fields. Existing approaches uses either single-hop transfer of data from SNs that lie within the MS's range or heavy involvement of network periphery nodes in data retrieval, processing, buffering, and delivering tasks. The authors' proposed protocol aims at reducing the overall network overhead and energy expenditure associated with the multi-hop data retrieval process while also ensuring balanced energy consumption among SNs and prolonged network lifetime.
