Link Quality-Based CDS (LQ-CDS) Construction in Smart Home Wireless Mesh Networks

Smart home wireless mesh networks (SH-WMNs) have emerged to become one of the promising applications of Wireless Sensor Networks (WSNs). In SH-WMNs, connected dominating set (CDS) is one of candidates for clustering formation or virtual backbone construction. During the CDS construction, however, the link that has enough bandwidth to support more end-devices should be selected in order to enhance overall network throughput and reliability. Our LQ-CDS construction scheme can improve the network performance via two metrics: interference metric and bandwidth metric. The simulation results show that LQ-CDS constructs the virtual backbone with the small subset ofDS and the link that has better bandwidth.
