The spread of micro-sensors, micro-computer and low-power wireless communication enable deployment of distributed sensor networks. Wireless sensor networks employ multi-hop communication to convey the measured information between faraway sensor devices and a sink device because transmission range of each sensor device is limited due to regulation and energy limit. Long-lived sensor networks are especially important to develop practical products for sensor networks. We make researches about Media Access Control (MAC) mechanisms, routing protocols, and micro-computer boards to realize autonomous sensor networks.
