| 摘 要： | 无线传感器网络要求的能量高效,低延时,使得MAC协议的设计充满挑战。近来已经提出了很多基于簇的MAC协议,为减少冲突在簇内部采用TDMA方式来协调簇内各个节点的传输。提出了一种在采用簇结构的基础上,使用预约方式来发送数据的R-MAC（Reservation-MAC）协议。当争用节点少的时候,采用随机争用方式来预约数据的发送;在争用节点多的时候,采用时隙争用方式来预约数据的发送。分析表明,R-MAC能够有效地降低能耗和减少延迟。

| Abstract: | The requirement of wireless sensor networks,such as energy efficiency and low delay,posed a great challenge for MAC protocol design.Recently many cluster-based MAC protocols are proposed,in order to reduce collision taking TDMA scheme to manage the intra-cluster communication.This paper proposed a cluster similar reservation-based MAC(R-MAC).When the contention nodes are fewer,the random con-tention way is used to reserve the data transfer. On the contrary,when the contention nodes are many,the slot contention way is used.The analysis shows that R-MAC gets better performance in terms of energy consumption and delay. |
