Abstract

Energy Efficiency is the prime concern for Wireless Body Area Network (WBAN). In this paper, a mathematical model for energy consumption per bit has been formulated. The association and dependence of energy on separation distance (d) between transmitting and receiving node, received power, data rate and pathloss has been evaluated. Based on the tradeoff between energy consumption per bit and data rate, a threshold distance (dth) is calculated using eigen values. Further, the performance of proposed WBAN model has been analyzed with respect to threshold distance. Simulation results support the value for threshold distance calculated and reveals that below dth, energy consumption per bit and data rate varies linearly. However, beyond dth data rate and energy consumption per bit exhibits an exponential increase. To signify the role of threshold distance a comparative analysis has been done for energy consumption per bit with different data rates supported by Ultra-Wide Band with respect to distance. It is revealed that beyond threshold distance the WBAN will be energy inefficient.

基于特征值的阈值距离评估及其对无线宽带网络性能的影响分析

能源效率是无线体域网络(WBAN)的首要问题。本文建立了单位钻头能耗的数学模型。评估了能量与发射和接收节点之间的分离距离(d)、接收功率、数据速率和路径损耗的关联和依赖关系。基于每比特能耗和数据速率之间的权衡，使用特征值计算阈值距离(dth)。在此基础上，分析了基于阈值距离的WBAN模型的性能。仿真结果支持阈值距离的计算值，并表明在dth以下，每比特能耗和数据速率呈线性变化。然而，超过dth的数据速率和每比特的能耗呈指数级增长。为了表明阈值距离的作用，对超宽带支持的不同数据速率下的每比特能耗与距离进行了比较分析。结果表明，在超过阈值距离时，无线宽带网络会出现能量不足的问题。
