Node energy in wireless video sensor networks（ WVSNs） is limited

in order to reduce energy consumption and prolong network lifetime

a novel communication protocol based on correlation-aware in WVSNs is proposed. Firstly

current typical routing protocol of WVSNs is analyzed to find the defects; secondly

cluster head node selection

cluster formation

and node sensing direction adjustment

communication within and inter cluster are improved and optimized; finally

simulation and comparison test are carried out on Matlab 2012 platform.Simulation results show that the proposed protocol can not only prolong network lifetime but also improve coverage rate of monitoring area.
