Wireless multimedia sensor network routing method for guaranteeing QoS

The invention relates to a multimedia sensor network routing scheme guaranteeing service quality, which refers to a wireless multimedia sensor network routing method, and is mainly used for solving the transmission problem of the data of a plurality of task flows existing in a wireless multimedia sensor network. The wireless multimedia sensor network routing scheme realizing guaranteeing the service quality is mainly characterized in that according to the own characteristics of a node, a role played in a routing path is automatically applied; according to cost on a link path, an optimal node is selected to establish a plurality of routing paths with different task flows; and when network topology changes, then routing path is dynamically renewed. By using the method of the invention, whenthe network is under a situation that a plurality of multimedia task flows are transmitted and applied, the multimedia task flows are real-timely and effectively transmitted, and the aim of reducing network congestion rate, i
