Abstract:
Wireless sensor network consisting of nodes equipped with cameras or advanced low-cost image sensors is known as a Visual Sensor Networks (VSN). The main function of VSNs is to capture images and send them to sink nodes for processing. One of the most common applications of VSN is surveillance. Such applications require large amounts of data to be exchanged between camera nodes and sink. Image data is considerably larger than common sensor data such as temperature, humidity, pressure, etc. For data delivery in VSNs, the communication is constrained by many stringent QoS requirements like delay, jitter and data reliability. Moreover, due to the inherent constraints of wireless sensor networks such as low energy, limited CPU power and scarce memory, the architect of VSN must choose appropriate topology, image compression algorithms and communication protocols depending on his/her application. This paper focuses on one of these aspects, namely the communication protocol for VSN. In this paper, we present a new routing framework for VSN to deliver critical imagery information with system's time constraint. We have implemented our proposed framework using Contiki and simulated it on Cooja simulator to support our claim.
