The nodes of Ad Hoc Wireless Network usually work by battery, mainly based on how to effectively reduce the consumption of electric force and prolong the note’ｓduration to enhance the life of the whole Network. Besides, this is one of the most significant items that many current researchers would like to explore. 　　This thesis is based on “Power-saving Virtual Grid Infrastructure for wireless ad hoc network routing,which utilizes both Pattern to create the waiting and sleeping states of the node,and Round-Rubin approach to dispose nodes to Pattern, together with adding schedule which enables the entrance of waiting and sleeping state. Secondly, we manipulate the Threshold mechanism to prevent the node with less electric from being excessively used for the purpose of reaching Network’s life. More than that,we also focus on RREQ problem in the face of PVGI transmission and reception, from which it results the issues of “Seeking the transmit node in the source side“ and ”The destination side which lies in sleeping situation”to revise and enhance the successful rate of path construction. of problem the problematic revision from which Routing means of PVGI results enables the further reduction of the electric consumption in Network nodes. 　　Through the trial and statistic data of the simulator system,it proves the usages of Pattern and Round-Rubin,together with the mechanism and schedule which enable node to get in the waiting and sleeping circumstance in proper time. Furthermore, it indeed can reach the objective of prolonging the Network duration.
