The invention discloses a low-energy consumption channel scanning method of a wireless multimedia sensor network. The low-energy consumption channel scanning method comprises the steps that: a terminal node and a route node firstly judge whether optimal channels used previously are optimal currently; if the optimal channels used previously are not optimal, the terminal node selects two channels numerically closest to the optimal channel used previously by the terminal node from optimal channels of other terminal nodes; the route node selects two channels numerically closest to the optimal channel used previously by the route node from optimal channels of other route nodes having the same ancestor node with the route node; and a channel with minimal channel energy is selected through scanning channels between two selected channels. For the wireless multimedia sensor network adopting multiple channels, the terminal node and the route node do not scan all channels in a channel space any more ...
