Implementation and evaluation of image transmission protocol in wireless multimedia sensor networks

Abstract

In wireless multimedia sensor networks (WMSNs), a multimedia sensor node captures an image and sends it to a server via multiple wireless hops. In this process, an image transmission protocol has some stringent requirements such as reliability in data transmission, energy consumption of nodes, and end-to-end delay. This paper implements an image transmission protocol called the pipelined cooperative transmission (PCT) protocol on WMSNs and evaluates its suitability in the viewpoint of the requirements. According to experiments, the protocol could deliver an image of 34 Kbytes within less than 0.4 seconds without any loss of packet and also about 94% of totally generated images, even with a long-distance multi-hop topology and the high interference of WiFi signals.
