As a novel way of acquiring and processing information , wireless sensor networks(WSN)have been an attractive research hot-spot all over the world. It is a late-model non-infrastructure wireless network,and can be used for testing,sensing ,collecting and processing information of monitored objects. WSN do not need the support of fixed networks, it has the fast and
