The routing protocol for high data collection rate in rechargeable wireless sensor networks

In Rechargeable Wireless Sensor Networks (R-WSNs), it is critical for higher data collection rate because sensors have to operate in a very low duty cycle owing to sporadic availability of energy. Therefore, surplus energy of a node can be utilized for strengthening packet delivery efficiency and improving data collection rate for all sensors. In this work, we propose a distributed algorithm to compute the optimal data generation rate for maximizing the network throughput, which is formulated as a linear programming problem. Through extensive simulation and experiments, we demonstrate our algorithm is efficient to maximize data collection rate in rechargeable wireless sensor networks.
