Environment monitoring and surveillance using video cameras and sensors have become increasingly important functions in urban centers. Specically, vehicles are ideally suited for surveillance complementing xed video cameras and sensors installed in the infrastructure. As on-board video cameras become more popular in public transportation and individually owned vehicles, these devices provide an excellent source for surveillance data. When these vehicles collaborate between each other and provide on demand video services, the vehicular ad hoc forms a service, which provides picture and video service to any client needing the data. Comparing with currently existing cloud network, the vehicle is no longer a cloudservice consumer; instead, it becomes the hardware provider to oer location basevideo and picture services. The service utilizes hardware APIs such as GPS,event recording cameras, and network connections. As a result, the surveillance application exploits the mobility of the service vehicles to extend surveillance coverage beyond the reach of static devices.
