Measurement study on the end-to-end data transmission in motorways surveillance system using Wireless Ad Hoc Camera Networks (WAHCN)

Camera-based surveillance is an important technology to monitor people, assets and places, for the applications of increasing physical security. Access to information services whilst on the move is becoming increasingly prevalent within transport systems. This paper examines motorway vehicles equipped with wireless communication nodes to obtain images from the cameras distributed along a motorway. Exchanging the data (images) still remains a challenge to provide access aboard vehicles, particularly when travelling on high-speed motorways. This paper performed an analysis to examine the performance of a Wireless Ad Hoc Camera Network (WAHCN) used in motorway surveillance systems. This paper focus on studying the effect of the number of hops between sender (camera) and receiver (vehicle), and number of packets generated per second (packets rate)by the camera node. An investigation was performed to check the effect of these parameters on the performance and behavior of the proposed system (WAHCN) to demonstrate a clear view of the suitable values for these parameters to get high performance and good quality of service (QoS) in this type of networks.
