The road surveillance based on wireless sensor network nowadays has received great attention and its
application has been extensively used in practice. In this application, when the invasion target moves from road entrance
to system protection points in road network, the nodes in wireless sensor network could detect the target timely and give
an alarm before the target reaches the protection points.There are three main types of algorithms for nodes awake in road
surveillance application presently, namely AAU(Always Awake-Up) algorithm, DC(Duty-Cycling) algorithm and Virtual
Scanning Algorithm (VISA). VISA, which tailored and optimized for road network surveillance, has better performance
than the others.This paper puts forward Virtual Scanning Algorithm based on Additional-area(VISAA), which introduces
the more sleep time of the nodes based on the Additional Communication Area, to ensure the surveillance more reliability
and effectively.The simulation results show that our algorithm has positive significance to improve the performance of
road surveillance.
