摘要: 多跳分层异构无线传感器网络(WSN)包含周期性短数据和明显方向性数据流,根据该特点,设计一种异构传感器网络基础层MAC协议(GFN-MAC),以均衡降低基础层的能量消耗和时延。异构无线传感器网络基础层在分簇时使用CSMA协议,完成分簇后节点运行GFN-MAC协议,利用交错的周期倍增同步休眠调度模式,使不同层节点运行不同频率的激活/休眠周期。仿真结果表明,与完全同步和交错同步调度方案相比,GEN-MAC的通信时延和系统能耗较低,吞吐量较高。

Abstract: In order to lower delay of transmission and save energy at the same time, GFN-MAC that proposes cross periodic double- increased synchronization sleep scheduling is designed for the foundation layer of heterogeneous Wireless Sensor Network(WSN) that has a character for multi-hop cluster structure, periodic short data and detection data stream. CSMA protocol is used when heterogeneous WSN is clustering. GFN-MAC is run when heterogeneous WSN has clustered. This sleep scheduling makes nodes in different layer of a cluster run different cycle to sleep and wakeup. Simulation result shows that this protocol can reduce the transmission delay and energy.

Key words: heterogeneous Wireless Sensor Network(WSN), MAC protocol, sleep scheduling, cross synchronization, periodic double- increased
