Description: The main functions of the wireless sensor network (WSN) is to realize the data release, the received information query is able to effectively transmit to inquirers. Release methods are usually based on the current data query information flooding mechanism, waste the limited energy. Although some recent data published protocol to solve the problem from a different extent, but does not guarantee the query success rate. Based on the circular node distribution network model is put forward a kind of can not only reduce energy consumption, and can improve the success rate of data models - diameter - string DCS (diameter - chord scheme). This mode made use of each circle chord is the nature of a fellowship with the vertical diameter. Based on this, advances the Two - Phase agreement. It is divided into Two works in information query in different stages, in the first lookup query when trigger 2 paragraphs. To reduce the number of Two - Phase delay was proposed based on priority and probability forward Two solutions. Theoretical analysis and experimental results show that the proposed data publishing protocol has better performance.
