无线传感器网络的系统节能研究

Study on an energy-efficiency system of wireless sensor networks

无线传感网络为能量受限系统,我们设计了一个无线传感器网络的节能系统,硬件上采用主控芯片MSP4301611单片机和射频芯片CC1101平台,软件上MAC层采用S-MAC协议及进行优化,在网络层路由协议引入蚁群算法并进行能量均衡改进。实验结果表明,该原型能较好地降低无线传感器网络和传感器节点的能耗,延长网络生存周期。

For wireless sensor networks energy limited, an energy-efficient system prototype has been proposal based on researching algorithm above for wireless sensor networks. Its hardware is based on MSP4301611 processor and CCllO1 RF chipset. In software, we optimize some protocols in order to reduce energy cost, such as MAC, routing protocol, etc. Experiment shows that this prototype can reduce energy consumption of networks and sensor nodes, and prolong the life cycle of wireless sensor networks.
