METHOD AND APPARATUS FOR SELECTING VIDEO CODING IN SOLAR-POWERED WIRELESS VIDEO SENSOR NETWORKS

摘要

Disclosed are a method and apparatus for selecting video coding according to energy in a solar energy based wireless sensor network. A method of selecting video coding according to energy in a solar energy based wireless sensor network, wherein each sensor node of the wireless sensor network divides a predetermined time into a plurality of slots and predicts solar energy collected for a predetermined time to save energy in each slot. After allocating, reallocating energy to each slot by reflecting the energy remaining in the previous slot every time one slot passes; A energy consumption prediction step of predicting energy consumption for each slot; And a mode selection step of selecting one of a plurality of operation modes by comparing the allocated energy and the consumed energy for each slot, wherein the plurality of operation modes have priority for each operation mode. The amount of energy used is higher, but the higher the amount of energy used, the higher the priority.
