In Wireless Sensor Networks (WSNs), QoS topology control achieves energy-efficiency by turning off redundant nodes and links, while still satisfying the given QoS requirement. However, existing topology control algorithms assume that links are either connected or disconnected. Recent experiments have shown that, besides the connected and disconnected region, a large percentage of links reside in the transitional region with fluctuating link qualities. In this paper, the authors propose both centralized and distributed solutions for QoS topology control, where they employ the opportunistic transmission to catch the best transmission opportunities on transitional links.
