Today’s era is the era of smart and remote applications exploiting advancement in sensors, cloud, Internet of things etc. Major application is in healthcare monitoring and support using wireless body area network (WBAN) in which sensor nodes sense vital physiological parameters and send to server through sink i.e. smart phone nowadays for seamless monitoring. The most significant issue in such applications is energy efficiency which leads to enhanced network life time that ensures uninterrupted seamless services. From source to sink data transmission may occur considering three different scenarios: source to sink single hop direct data transmission irrespective of in-between node distance, source to sink multi hop data transmission in which transmission range of source node is fixed at a threshold to find next forwarder node and transmission range of source node is incremented by affixed value until data gets transmitted to sink. In this work WBAN having different network configurations based on fixed or random positions of nodes have been simulated. Different scenarios with fixed and varying number of nodes are framed and simulated using MATLAB 2020a for performance evaluation of proposed algorithm in terms of energy consumption, network lifetime, path loss etc. due to data transmission from source to sink. Experimental results show that incremental approach is better than direct one in terms of energy consumption, path loss and network lifetime. While selecting transmission range of a source node, it is considered to keep Specific Absorption Rate (SAR) lower to reduce impact on human tissue.

今天的时代是利用传感器，云，物联网等方面的先进技术的智能和远程应用程序的时代。主要应用程序是使用无线人体局域网（WBAN）的医疗保健监视和支持，其中传感器节点可感知重要的生理参数并将其发送到服务器通过接收器（即当今的智能手机）进行无缝监控。在此类应用中，最重要的问题是能源效率，这会延长网络的使用寿命，从而确保不间断的无缝服务。考虑三种不同的情况，可能会发生从源到接收器的数据传输：源到接收器的单跳直接数据传输，而不考虑节点之间的距离；源到宿的多跳数据传输，其中源节点的传输范围固定在一个阈值以找到下一个转发器节点，并且源节点的传输范围增加固定值，直到数据被传输到宿。在这项工作中，已经基于节点的固定或随机位置模拟了具有不同网络配置的WBAN。使用MATLAB 2020a对具有固定和可变数量节点的不同场景进行了框架化和仿真，以从能量到网络寿命，由于从源到接收器的数据传输而导致的路径损耗等方面对所提出算法的性能进行评估。实验结果表明，增量方法在能耗，路径损耗和网络寿命方面都优于直接方法。在选择源节点的传输范围时，
