Abstract: This paper conducted a technical survey for the recent development of wireless sensory networks (WSN) and their potential applications in pollution monitoring in the livestock, poultry and aquaculture industry. WSN as one of the emerging technology evolved and developed from wireless communications, VLSI (Very Large Scale Integrated Circuits) technology and sensor technology. It integrated environment sensing, data processing and wireless communication functionality into one unit, suitable for ecological environment monitoring and pollution prevention. In this paper, we have looked at this technology applications in poultry and aquaculture industry. In addition, we have discussed the guidelines to address practical deployment of WSN: first, selection of proper wireless transmission bandwidth and protocols to achieve communication reliability and meet the desired data rate; secondly, choose modularized sensor interface hardware to optimize the cost-performance ratio and to gain inter-operability to the existing sensors.

Key words: wireless senor network; real-time environmental online monitoring; pollution source real-time monitoring, water pollution monitoring, aquaculture industry
