多径衰落影响下的无线传感器网络分布式共识
Distributed Consensus over Wireless Sensor Networks Affected by Multipath Fading
摘要：
传感器网络的设计能够达成共识的全局最优决策测试，而不需要一个融合中心，是一个问题，在过去几年中受到了相当大的关注。已经提出了许多共识算法，其收敛条件取决于描述节点之间的交互的图。在大多数工作中，图是无向的，并且没有传播延迟。只是最近，分析已扩展到共识算法纳入传播延迟。在这项工作中，我们提出了一个共识算法能够收敛到一个全局最优的决策统计，使用宽带无线网络，由一个相当简单的MAC机制，其中每个链接是一个多路径，频率选择性，信道。本文的主要贡献是推导出网络拓扑的充分必要条件和信道传递函数的充分条件，保证指数收敛的共识算法的全局最优决策值，任何有界延迟条件。
英文摘要：
The design of sensor networks capable of reaching a consensus on a globally optimal decision test, without the need for a fusion center, is a problem that has received considerable attention in the last years. Many consensus algorithms have been proposed, with convergence conditions depending on the graph describing the interaction among the nodes. In most works, the graph is undirected and there are no propagation delays. Only recently, the analysis has been extended to consensus algorithms incorporating propagation delays. In this work, we propose a consensus algorithm able to converge to a globally optimal decision statistic, using a wideband wireless network, governed by a fairly simple MAC mechanism, where each link is a multipath, frequency-selective, channel. The main contribution of the paper is to derive necessary and sufficient conditions on the network topology and sufficient conditions on the channel transfer functions guaranteeing the exponential convergence of the consensus algorithm to a globally optimal decision value, for any bounded delay condition.
