Abstract

Abstract:

A multiple description coding transmission strategy proposed to solve the problem of low wireless network connectivity but high transmission quality requirements in wireless multimedia sensor networks (WMSN). This strategy makes multiple descriptions coding on the source node, selects initial broadcasting nodes, and then builds multiple transmission paths. The strategy is applied in image transmission application where the performance is evaluated in terms of data arrival ratio, and comparied between transmitted image, the original one, and peak signal to noise ratio. Experiment shows that the strategy improves wireless network connectivity and assures transmission reliability of WMSN.

Key words: multiple description coding, wireless multimedia sensor networks, performance
