Outline of Final Research Achievements

Rechargeable sensor networks have been studied as a candidate for next generation wireless sensor networks. However, power supplement of energy harvesting is unstable, which is different from battery powered network. Therefore, when a node sends data, the relay nodes are not always available for receiving or transmitting. In this paper, we propose a two-dimensional routing protocol based on the power generation pattern of the sensor node. Furthermore, we also propose a synchronization protocol to support the uneven charge-rate of the sensor node. In our protocol, each sensor node sends its power generation pattern and charge rate to the neighboring node. The information is used to decide the selection the destination node. The preliminary evaluation shows that the proposed protocols are able to achieve higher delivery ratio than the previous work.
