Comparison of sensor management policies.

	QoS criteria		Application
Sensor management policy	Energy efficiency	Bandwidth allocation	Large scene monitoring	Object tracking	Goal of sensor management metric
Dagher et al. [52]	Yes	No	Yes	No	Battery lifetime optimization
Park et al. [53]	No	No	Yes	No	Quality of view for every 3D point
Soro and Heinzelman [54]	Yes	No	Yes	No	Exploring trade-offs between the image quality of reconstructed views and energy efficiency
Zamora and Marculescu [55]	Yes	No	No	Yes	Coordinated-wake up policies for energy conservation
Yang and Nahrstedt [56]	No	Yes	No	Yes	Proposed several sensor selection policies (random, event-based, view-based, priority-based) that consider bandwidth constraints
Pahalawatta et al. [25]	Yes	No	No	Yes	Maximize sum of information utility provided by the active sensors subjected to the average energy that can be used by the network
Ercan et al. [29]	No	No	No	Yes	Object occlusions avoidance
