Embodiment Construction

[0047] 1. Architecture

[0048] The QoS-guaranteed routing method for wireless multimedia sensor networks is a method for distributing multiple multimedia task flows into multiple routing paths. This method not only guarantees the transmission of various task flows, but also establishes multiple paths to balance network energy consumption, reduce network congestion, dynamically maintain network routing paths and prolong network life cycle. Among them, the intra-cluster route generation module, the inter-cluster route generation module and the route path maintenance module are the main functional components for realizing the method of the present invention.

[0049] The following is a description of several specific parts:

[0050] Routing path mapping table: each cluster head node on the trunk routing path saves the previous hop node number, next hop node number, multimedia task flow symbol and candidate cluster head node number of each multimedia task flow routing path; The...

Abstract

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, when the 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, increasing network huff, fully playing the function of each node in the network, balancing network energy consumption, effectively utilizing the resources of the whole network, and improving the survival period of the whole network is achieved.
