Research of routing algorithm for wireless sensor network

The wireless sensor network is composed of many low price sensor nodes, these sensor nodes form multi-hop wireless network and complete the large-scale sensing task in cooperation. The wireless sensor network has a widespread application prospect, it has attracted people´s universal attention. In this paper, the traditional wireless sensor network´s routing algorithm is analyzed and a directed routing tree algorithm based on improved flooding is proposed. This algorithm applied flooding strategy to construct a directed sink tree with the sinks as the root, and then inquired the neighboring nodes through agent, if the node was no longer in the adjacent, the search would be taken around this node, finally the route was repaired.
