DSMAC:An energy-efficient MAC protocol in Event-driven Sensor Networks

摘要：

In this paper we present DSMAC-an energy efficient medium access control (MAC) protocol in wireless sensor networks which are widely used for long-time monitoring.Our protocol is designed for event-driven and ultra-low power sensor networks.Using dynamic sleep scheme to save energy is one of the key problems in this kind of system.The basic idea is that,when an event is apperceived by sensors,all nodes in the network use a value of grads to earmark the location of an event,which is used for data searching expediently,and all nodes adjust their sleep periods dynamically due to their grads.Simulations show that,our MAC protocol for event-driven wireless sensor networks shows higher efficiency than exists approaches and is more suitable for long-time monitoring.
