摘要

技术的发展和电信、无线通信、无线传感器和其他技术的日益进步,导致了这种微型传感器的发展,这种传感器可以植入人体或在人体上。这个创新和令人振奋的研究领域是无线体域网络(WBAN)。低功耗和可靠的数据传输是使用WBAN的医疗系统的首要要求。本文首先探讨了无线宽带网络的高效路由算法,然后根据路由梯度、能量感知期望传输等因素对其进行了改进。提出了WBAN的节能树路由算法,并与Ad-hoc随需应变距离矢量路由(AODVR)算法进行了比较。该算法通过对现有算法的改进,共同解决了数据可靠传输的低功耗和端到端延迟问题,使节点能够通过最小化传输功率来鲁棒选择路由路径。在omnet++ 4.5环境下进行了大量的实验,通过测量功耗和包接收比(PRR)等因素来确保所提出的EETR算法的成功实现。实验结果分析表明,EETR算法比AODVR算法更适用于基于wban的节能健康监测。通过大量的实验,对单跳星型拓扑和基于树的多跳树拓扑进行了比较。

Tree based energy efficient routing scheme for body area network
Evolution of technology and day by day advancements in telecommunication, wireless communication, wireless sensors, and other technologies has led to development of such miniaturized sensors which can be implanted in or on the human body. This innovative and exhilarating area of research is Wireless Body Area Network (WBAN). Low power consumption and reliable data transmission is primary requirement in medical systems using WBAN. In this paper, we firstly explore efficient routing algorithm for WBAN and then it is modified to add energy factor with respect to routing gradient, energy aware expected transmission. Energy Efficient Tree Routing (EETR) algorithm is proposed for WBAN and it is compared with Ad-hoc On Demand Distance Vector Routing (AODVR) algorithm. This algorithm can jointly address the issue of low-power consumption and end-to end delay for reliable data transmission by modifying current algorithm so that nodes can robustly choose routing paths by minimizing the power levels for transmission. Considerable experiments are conducted using OMNET++ 4.5 as environment to ensure the successful implementation of proposed EETR algorithm by measuring number of factors like power consumption and Packet Reception Ratio (PRR). Experimental result analysis shows that EETR algorithm is beneficial than AODVR algorithm for energy efficient health monitoring using WBANs. In particular, single hop star topology and tree based multi-hop tree topology is compared with the help of extensive experiments conducted.
