ROUTING METHOD FOR QUALITY OF SERVICE GUARANTEE FOR CONSIDERING CONGESTION STATUS IN WIRELESS MULTIMEDIA SENSOR NETWORKS

摘要

The present invention relates to a routing method of quality of service (QoS) guarantee for considering a congestion status in wireless multimedia sensor networks. The routing method comprises the steps of: classifying traffics by assigning a priority order to a transmission packet; calculating a path cost for making transmission to a sink node according a classified packet priority order; and dispersing a load to a replacement node by determining an overload node according to a congestion degree and a buffer occupancy of a random node, and changing a path to the sink node by the overload node.
