一种无线社区医疗监护网络的设计

临床护理中的很多医疗监护设备,需要实时采集病人的血压、心电、血氧和体温等指标,但这些设备一般存在体积大、耗电高、设备固定以及接线繁多等缺点。设计了一种部署在居民社区、小区的无线传感器网络,并提出一种MHDC-LEACH(改进的多跳分簇路由)算法。仿真结果表明,与传统的LEACH算法相比,该算法可减少网络中节点与基站通信的次数,均衡网络负载,优化数据传输路由,延长网络的生命周期,有效减少死亡节点个数。当网络覆盖区域增大时,最多可节约网络能量约20%。

Design on a Wireless Community Healthcare Monitoring Network

Many medical devices used in clinical nursing care field need to measure and collect blood pressure, ECG, blood oxygen ,body temperature and other index in real-time, but these devices always have such disadvantages as big volume, high power consumption, fixed installation and complex connections. This paper designs a kind of wireless sensor network which can be used in community, and a new algorithm named MHDC-LEACH（ improved routing protocol algorithm）is proposed. The simulation results show that the improved protocol can reduce the frequency of communication between BS and WSN nodes,balance the energy dispatch,make progress in data transfer routing ,prolongs the life of network and reduce the number of dead nodes, compared with traditional LEACH protocol. As the network coverage becomes larger, it can save energy about 20%.
