Target coverage QoS control with multiple sensing units in wireless heterogeneous sensor networks

A wireless heterogeneous sensor networks (WHSNs) is a kind of wireless sensor networks (WSNs), each sensor may have different sensing units. Sensing nodes can simultaneously monitor different attributes, such as various temperature, brightness, humidity, and so on. MUQC use the changes in number of sensing units and sensing units to adjust the probability of on mode and off mode. After several rounds, the operational number of sensors to achieve the desired number of targets. The result showed that MUQC can effectively schedule the activity of each sensing unit on each sensor to completely cover the targets of interest and turn on the sensing attributes of the sensors in the appropriate round.
