由于传感器技术和超大规模集成电路的不断改进，无线传感器网络已成为可能。智能传感器网络的一个问题是由于可用功率有限而实现高效运行。对于重要类别的传感器网络，例如生物医学传感器，传感节点的位置是固定的并且可以预先确定放置。在本文中，我们考虑最能支持这些传感器节点之间通信的拓扑。我们提出了一种功率感知路由协议并模拟了性能，表明我们的路由协议可以根据可用功率调整路由。这会减少总功耗，并使节点间的功耗更加均匀。我们考虑不同的路线和拓扑，展示性能差异并解释根本原因。
Wireless sensor networks have become possible because of the on-going improvements in sensor technology and VLSI. One issue in smart sensor networks is achieving efficient operation because of the limited available power. For important classes of sensor networks, such as biomedical sensors, the locations of the sensing nodes are fixed and the placement can be pre-determined. In this paper, we consider the topology that best supports communication among these sensor nodes. We propose a power-aware routing protocol and simulate the performance, showing that our routing protocol adapts routes to the available power. This leads to a reduction in the total power used as well as more even power usage across nodes. We consider different routes and topologies, demonstrating the difference in performance and explaining the underlying causes.
