Image transmission method in wireless camera-based sensor networks by using variable interleaving approach

The Wireless Multimedia Sensor Network is a distributed sensor network consisting of a group of multimedia sensor nodes that have the capabilities of computing, storage and communication. The multimedia sensors nodes sense environment multimedia information first and send them to the central processing node like sink or human. The availability of low-cost hardware such as cameras has fostered the development of wireless camera-based sensor networks, networks of wirelessly interconnected devices that are able to capture video streams, still images from environment. Image sensor nodes suffer problems such as heavy data traffic, limited energy and computation capability. In wireless camera-based sensor networks, energy consumption of nodes is used to image transmission and processing, so it is one of the considerable challenges in these networks. This paper, proposes a new approach to reduce energy consumption along with increasing networks lifetime.
