Research of Short Preamble MAC Protocol for Energy Efficient in Wireless Sensor Network
- 발행 : 2010.01.01
Idle listening is very critical source of energy dissipation in wireless sensor networks. To reduce idle listening, we propose preamble sampling MAC that is named EESP-MAC. The main idea of EESP-MAC is to add control information into the short preamble frame. So the stream of short preambles is used not only for preamble sampling but also for avoiding overhearing, decreasing control packet overhead and reducing the listening of the redundant message, caused by message-flooding.
