摘要
Wireless sensor network (WSN) is a multi-hop, self-organizing distributed network system composed of multiple micro-sensors through wireless communication. There are problems such as energy holes and transmission link interruption due to node failure for multi-hop mode of data transmission. Mobile sink (MS) supports data forwarding and collection to avoid multi-hop transmission, extending network life by saving network energy. In the work, we discussed transmission energy and delay problems of data collection by MS in WSN with duty cycle. Based on fixed MS moving speed and regular transmission performance, the network life cycle was maximized to propose an asynchronous path independent energy efficient algorithm irrelevant to the path. After that, the efficiency of the protocol was verified by experiments.
