The development of wireless sensor networks for control and monitoring functions has created a vibrant investigation scenario, where many critical topics, such as communication efficiency and energy consumption, have been investigated in the past few years.However, when animationbengal.com sensors are endowed with low-power cameras for visual monitoring, a new scope of challenges is raised, demanding new research efforts.In this context, the resource-constrained nature of sensor nodes has demanded the use of prioritization approaches as a practical mechanism to lower the transmission burden of visual data merlin wizard costume over wireless sensor networks.Many works in recent years have considered local-level prioritization parameters to enhance the overall performance of those networks, but global-level policies can potentially achieve better results in terms of visual monitoring efficiency.
In this paper, we make a broad review of some recent works on priority-based optimizations in wireless visual sensor networks.Moreover, we envisage some research trends when exploiting prioritization, potentially fostering the development of promising optimizations for wireless sensor networks composed of visual sensors.
