Energy Saving in Wireless Video Sensor Networks using Online Data Transmission Reduction Scheme

Wireless Video Sensor Networks (WVSNs) are used in many monitoring applications in various fields such as security, military, industrial, medical, and environmental. The video sensor nodes in these networks gather huge amounts of data and transmit it across the network. Transmitting the collected huge data will lead to increased energy consumption, bandwidth usage, and congestion over the WVSN network. Reducing energy for processing and transmitting data in WVSNs is difficult due to the huge amount of sensed data in real time. this paper proposes an Online Data Transmission Reduction Scheme (ODaTReS) to address energy conservation in WVSNs. The data reduction by the ODaTReS is based on two phases: the sensing phase and the transmission phase. Where ODaTReS employs frame rate adaptation using the ORB (Oriented FAST and Rotated BRIEF) algorithm in the sensing phase to limit the captured video frames. While in the transmission phase, it computes the matching ratio between frames. Experimental evaluations demonstrate the superiority of ODaTReS over other methods in terms of data reduction ratio, energy consumption, data quality, and validity.
