Wireless Body Area Sensor Networks are related to the monitoring of human physiological parameters. In these small sized machines called sensors are used to observe the physiological parameters. They are small in size which makes them easy to carry around but on the same time they have a serious problem that they can carry with them a very small sized battery. The sensors deplete their energy while sensing the parameter, communication of the sensed data to the base station and also in processing of the observed data. The sensors cannot be charged on regular intervals because they are attached to human body and charging them may not be an easy option. In this paper an energy efficient routing protocol is presented which uses sensors in WBASN to observe parameter in much efficient way. The concept of multi hopping has been utilized with forwarder node. Forwarder node accepts data from sensor nodes which are far from the sink. After accepting data the forwarder node forwards this data to the sink node. This scheme is compared with an existing scheme with which it has been compared in terms of four parameters which are residual energy, network stability and life time, throughput and path loss.

无线人体区域传感器网络与人体生理参数的监视有关。在这些称为传感器的小型机器中，用于观察生理参数。它们体积小，便于携带，但同时存在一个严重的问题，即它们只能携带非常小的电池。传感器在感测参数，将感测到的数据传输到基站以及处理观察到的数据时会消耗其能量。由于传感器已固定在人体上，因此无法定期给传感器充电，因此可能不容易为传感器充电。本文提出了一种节能路由协议，该协议使用WBASN中的传感器以非常有效的方式观察参数。多跳的概念已与转发器节点一起使用。转发器节点从距离接收器较远的传感器节点接收数据。接受数据后，转发器节点将此数据转发到接收器节点。该方案与现有方案进行了比较，现有方案已通过四个参数进行了比较，这四个参数分别是剩余能量，网络稳定性和寿命，吞吐量和路径损耗。
