Serial Distributed Detection in Multihop Multirelay Wireless Sensor Networks With End–Edge–Cloud Orchestration Under Graph-Powered Computing

<p>Abstract—The decision fusion rule and global optimality is<br>studied for serial distributed detection in multihop multirelay<br>wireless sensor networks (WSNs) under the end–edge–cloud<br>orchestration. In particular, a multihop relay node serial distributed<br>detection configuration is considered. Then, the optimal<br>decision fusion rule is derived, and the detection probability<br>and false alarm probability of the distributed detection system<br>are given. Third, the suboptimal decision fusion rule under<br>different conditions for the multihop relay channel is represented.<br>Furthermore, in order to solve the high energy consumption and<br>bandwidth limitation problems of WSNs, we consider the global<br>optimization for serial distributed detection systems and obtain<br>the sufficient condition. Finally, under different communication<br>conditions, the detection performance of the system has been<br>kept optimal when we increase the number of sensors in series.<br>We validate the conclusions based on the numerical results. The<br>sufficient condition for optimality detection of serial distributed<br>detection multirelay sensor network system is satisfied then the<br>system can achieve optimal detection performance.</p>
