In this paper, we present two practical algorithms for selecting a subset of channels in virtual multiple-input-multiple-output (MIMO) wireless sensor networks (WSNs) to balance the MIMO advantage consumption of sensor cooperation. If intracluster node-to-node multihop needs be taken into account, the maximum spanning tree searching (MASTS) algorithm, with respect to the cross-layer design, always...
In this paper we investigate a methodology named channel selection with the aim of balancing the multiple input multiple output (MIMO) advantage and the complexity of node cooperations for wireless sensor networks (WSN). In respect of cross-layer design, we propose the Maximum Spanning Tree Searching (MASTS) algorithm to select a set of subchannels that always provide a path connecting all sensors...
In this paper, we present singular-value decomposition- QR with threshold (SVD-QR-T) algorithm to select a subset of channels in virtual MIMO wireless sensor networks (WSN) in order to reduce its complexity and cost. SVD- QR-T selects best subset of transmitters while keeping all receivers active. The threshold is adaptive by means of fuzzy c-mean (FCM). Under the constraint of the same total transmission...
