摘要: 无线传感器网络中节点的能耗直接影响了节点工作的持久程度,研究和优化 MAC 协议能够有效解决节点的能耗问题。基于无线传感器网络操作系统 TinOS 对 MAC 协议进行研究,在对现有无线传感器网络 MAC 协议分析的基础上,结合区分优先级的思想,提出一种区分优先级的无线传感器网络 MAC 协议,以实际的硬件节点 CC2538 来探究 MAC 协议的改进以及对其性能的验证。结果表明该区分优先级的无线传感器网络 MAC 协议在负载较高时有着较好的 OoS 保障,能够有效降低节点的能量开销。

Abstract: The energy consumption of nodes in the wireless sensor networks directly affects the enduranceof the nodes. Optimization of the MAC protocol can effectively solve the energy consumption problem ofnodes. A prioritized wireless sensor network MAC protocol is studied based on TinyOS, a wireless sensornetwork operating system. The actual hardware node CC2538 is used to explore the improvement of theMAC protocol and the verification of its performance. The results show that the proposed prioritized MACprotocol for wireless sensor networks has better OoS guarantee when the load is high, and can effectivelreduce the energy cost of nodes.

Key words: quality of service;wireless sensor network, MAC protocol
