In Wireless Sensor Networks (WSNs), barrier deploy is a hot topics. Barrier deploy for dynamic area is mobility and unsure. It is an important issue that sensors form an effective barrier. In this paper, the authors describe the problem of barrier deploy for dynamic area, define performance evaluation indexes of barrier deploy. A moved barrier deployment algorithm based on swarm intelligence of artificial fish swarm algorithm is developed. Sensors can quickly find the border of the target area so as to form a closed barrier and response of the change of the target area.
