【摘要】 简要分析了无线传感器网络MAC层协议的作用,针对MAC协议在低时延方面的不足,提出了一种低时延的MAC协议(L-MAC)。该协议采用汇聚树,在满足低功耗的基础上,减少了时延。理论分析和仿真实验表明L-MAC较好地解决了时延问题。更多还原

【Abstract】 Simple analysis is made in MAC for wireless sensor network. Taking account of the drawbacks in low latency of the existing MAC protocols, a low-latency MAC Protocol (L-MAC is put forward. The protocol adopts the gathering tree to reduce low latency, which is on a base of satisfying energy efficient. The theoretical analysis and the simulation show that L-MAC can solve low latency efficiently.更多还原
