Simulation of a wireless senor network for image processing

The use of ad-hoc senor networks for transmitting multimedia data such as still images or streaming video requires significant throughput and minimum delay. In this paper, we analyse and simulate how mobility in the relay nodes affects the QoS required by these applications for both Bellman-ford and AODV routing algorithms. In this project, we are allocating three types of nodes. The front-end nodes capture images and pass them to the relay nodes that in turn route them to the pre-processor or server. We will show in this paper that the size of the field limits the maximum transmission rate of images for both algorithms. However, when the mobility ratio of the relay nodes is very low, meaning most of the nodes are static, the throughput for transmitting images improves considerably. The mobility of the front end nodes on the other hand, has less effect on the total throughput. In all the cases, we noticed that the performance of the bellman-ford routing algorithm is higher than that of AODV.
