Research and analysis on routing protocols for wireless sensor networks

Wireless sensor networks (WSNs) are the products which integrate sensor techniques, embedded techniques, distributed. information processing and communication techniques. The appearance of the wireless sensor network is a revolution in information sensing and detection. Recently, both academia and industry have shown great interest in sensor networks. The paper introduces the architecture of the wireless sensor network and WSN features. It then studies recent routing protocols for wireless sensor networks and presents a variety of classifications of them; it also contrasts and compares representative routing protocols. Several future open issues of the wireless sensor networks are put forward.
