MULTIPLE PATH PRIORITY ROUTING METHODS FOR WIRELESS SENSOR NETWORK AND ROUTING APPARATUS FOR PERFORMING THE SAME

摘要

In a wireless sensor network environment including a source node, a router, and a destination node, a multi-path priority routing method performed by the router is classified according to a packet acceptance policy. Inserting the packets into a plurality of queues according to priority and determining the packet processing rate of each queue according to the priority, and processing each packet according to the packet processing rate of the queue in which the corresponding packet is inserted; , Determining a routing path of each queue according to the priority, wherein each queue has a different routing path, and distributing and transmitting the classified packets to a routing path determined according to the priority. Different types of packets, such as routing control packets, real-time packets, and non-real-time packets, are simultaneously delivered to the receiver through multiple paths to distribute the load, prevent wireless communication congestion, and maximize the path utilization of the routing path. have.
