一种高吞吐量的WBAN多跳协议

A Multiple Hops Protocol with High Throughput for WBAN

为提高无线体域网(Wireless Body Area Network,WBAN)能量效率和实现高吞吐量,提出一种多跳拓扑结构来节约能耗,延长网络寿命。通过设定代价函数选出前驱节点,使得被选用节点具有较多的剩余能量和较小传输间距。代价函数的剩余能量参数用于平衡传感节点的能量损耗,距离参数确保包交付成功率。仿真结果表明,该协议得到稳定的高吞吐量,有助于WBAN对人体病症的连续监测。

To improve the energy efficiency of wireless body area network（ WBAN） and achieve high throughput,a kind of multiple hops topology is put forward to save energy consumption and prolong the network life.A cost function is set to select a precursor node that has more residual energy and less transmission distance.The residual energy parameters of the cost function are used to balance the energy loss in the sensor node,while the distance parameters are used to ensure the success rate of packet delivery.Simulation results show that the protocol can get a stably high throughput,helping WBAN continuously monitor the conditions of human body.
