In mobile computing environments, as handheld devices' small-screen, limited computing ability and capacity of storage, consumers still experience difficulties when browsing the web on such devices. Some researches focus on how to adapt a normal web page to handheld device. Meanwhile, it is necessary to put existing web adaptation engines into practice. To meet the requirement, a new scheme of mobile device oriented web page adaptation based on P2P collaborative deployment is proposed: on the premise of splitting a normal web page into small logical blocks, a P2P collaborative deployment scheme is provided; a specific algorithm is designed to assign blocks, manage devices, coordinate devices and decide how to carry exiting web adaptation engine by the using of P2P collaborative work mode; moreover, a prototype system and its evaluation experiments have been implemented to verify the scheme and show its values in both technical and economical viewpoints.
