| 摘 要： | 提出一种无线体域网(WBAN, wireless body area network)的网络拓扑结构设计方案。该方案针对IEEE 802.15.6标准的2跳扩展星型拓扑结构，建立基于混合整数非线性规划的能耗成本优化模型，通过调整中继节点的位置和数量，以及数据到汇聚节点的路由，获得优化的网络拓扑结构。实验结果分析表明，与Elias提出的EAWD(energy aware WBAN design) 模型相比，所提出的方案能使网络能耗减少40.5%，网络时延平均降低52.4%，网络寿命提高了一倍。

| Abstract: | An optimization model was proposed to design the network topology of wireless body area network(WBAN).Focusing on the two hops extended star topology given in IEEE 802.15.6 standard,a mixed integer non-linear programming model was constructed to minimize the energy consumption of WBAN.Then,the optimized network topology was obtained by adjusting the number and location of relays to be deployed and the data routing towards the hub.The experimental results show that,compared with Elias’s model (EAWD,energy aware WBAN design),the proposed model can reduce network energy consumption by 40.5%,decrease network delay by 52.4% on average,and extend network lifetime by double. |
