Dual-band automatic gain control algorithm for chirp spread spectrum over indoor fading channels

Recently there have been many research topics in wireless sensor networks (WSN) for efficiently monitoring the environments, and localizing, detecting, and classifying targets of interest. Most of these researches assume that the environment to be stable. On the other hand, if the sensor nodes are deployed randomly, the establishing connection between the sensor nodes is critical importance. In this paper, a new heuristic algorithm has been designed for effectively connects with the clusters of sensor nodes that are not connected with the sink by using non relay sensor movement (NRSM) procedure.
