Exploiting low overhead compression accompanied by proper routing and aggregation is a challenge for such energy starved multihop network. In this paper, we propose an efcient path merging protocol for wireless multimedia sensor net- work with randomly deployed nodes. Any partial discrete wavelet transform based com- pression technique can be plugged into this path merging protocol to reduce redundant data transmission in a signifcant manner by appropriate aggregation of data packets from merg- ing paths. The design feasibility and the simulation results prove supremacy of our proto- col over state-of-the-art competing schemes in terms of maintaining a trade-of between energy consumption and reconstruction quality.

Such networks have enormous usage, e.g. trafc monitoring, industrial automation [2–4]. For example, in real- ity, arrays of video sensors are already used by oceanographers to determine the evolution * Rajib Banerjee rajib123banerjee@gmail.com Sibashis Chatterjee sibashisch@redifmail.com Sipra Das Bit sdasbit@yahoo.co.in 1 Department of Electronics and Communication Engineering, Dr. B.C.
