| 针对传统无线传感器网络MAC(medium access contro1)协议节点能耗高的问题,采用跨层设计的思想,在自适应S-MAC(sensor MAC)协议的基础上,提出了CLEE-MAC(cross layer based energy-efficient MAC)协议.该协议通过利用路由层的信息,改变自适应S-MAC 协议的控制包格式,充分利用并减少了串音监听,同时简化多跳传输的控制开销,提高了节点能量的利用率,并降低了数据传输的时延. |

| Abstract: |
| The MAC (medium access contro1) protocol of traditional wireless sensor network has a problem with the high energy consumption of nodes. This paper proposes a CLEE-MAC (cross layer based energy-efficient MAC) protocol using the thought of cross-layer design, based on adaptive S-MAC (sensor MAC) protocol. The CLEEMAC protocol changes the format of control packets of S-MAC protocol with the information coming from a routing layer. It makes the most and reduces the overhearing listening, and at the same time, simplifies the control overhead of multi-hop transmission, improves the utilization of nodes energy, and reduces the delay of data transmission. |
