Abstract

Wireless Body Area Network (WBAN) comprises wireless sensor nodes that can be either on, implanted or around the body of a person. Routing in WBAN network is not the same as routing in Wireless Sensor Network (WSN) because WBAN protocols have to be thermal aware and data delivery has to be more reliable. Though different WBAN routing schemes have already been proposed, they are not energy efficient or they are unable to relay critical health data reliably. In this paper, a Multi hop routing protocol for WBAN has been proposed that is efficient in terms of transmitting power, Packet delivery Rate (PDR) and network lifetime. Fixed nodes are added to WBAN that are used as forwarder nodes. Proper subset of fixed nodes and sensor nodes can be selected as forwarder based on a cost function that includes metrics like transmission power of the node, velocity vector of the receiver, residual energy and the current location of the node with respect to the coordinator. Simulation studies show that the proposed protocol maximizes network life time and increases packet delivery.

一种新的无线局域网路由协议，以提高能耗和网络寿命

无线身体区域网络(WBAN)包括无线传感器节点，这些节点可以在人的身体上、植入或周围。WBAN网络中的路由与无线传感器网络(WSN)中的路由不同，因为WBAN协议必须具有热感知能力，并且数据传输必须更加可靠。虽然已经提出了不同的无线宽带网络路由方案，但它们都不节能，或者无法可靠地中继关键的健康数据。本文提出了一种基于WBAN的多跳路由协议，该协议在传输功率、分组传输速率(PDR)和网络寿命方面都是高效的。固定节点被添加到WBAN中，用作转发器节点。可以根据成本函数选择固定节点和传感器节点的适当子集作为转发器，成本函数包括节点的传输功率、接收器的速度矢量、剩余能量以及节点相对于协调器的当前位置等指标。仿真研究表明，该协议最大限度地延长了网络的生存时间，提高了数据包的吞吐量。
