这封信研究了非对称无线传感器网络的功率分配问题，其中多个传感器观察公共二进制源并将其损坏的观察结果传输到数据融合节点。我们提出了一种功率分配方案，通过在总功率约束下最大化加权信道容量，并证明该问题是凸的。仿真结果验证了所提出的功率分配方案优于统一功率分配方法。此外，通过确定主导误码率性能的传感器，提出了二进制数据收集的调度方案。
This letter investigates the power allocation problem for an asymmetric wireless senor network, where multiple sensors observe a common binary source and transmit their corrupted observations to a data fusion node. We propose a power allocation scheme by maximizing the weighted channel capacity subject to the sum power constraint and show that this problem is convex. The simulation results verify that the proposed power allocation scheme outperforms the uniform power allocation method. Furthermore, a scheduling scheme for binary data gathering is proposed by determining the sensors that dominate the bit error rate performance.
