Energy Harvesting Path Planning Strategy on the Quality of Information for Wireless Sensor Networks

Wireless Sensor Network consists a large number of sensor nodes and a small number of sink nodes that are scattered throughout the area to monitor the environment. Due to the long distance between sensor and sink, the data is usually sent to sink in a multi-hop manner. Mobile sink itself has the energy limitation, while mobile sink moving in the environment may lead to information beyond the environmental delay and reduces the quality of information. Considering remaining sensor storage space and sensor data quality, we designed a mobile sink path planning strategy to ensure the quality of information. In addition to the theoretical study, this paper also implements the developed mechanisms in simulator.
