Dynamic Routing Control Based on Information Priority and Its Application to Monitoring Sensor Networks

Abstract

SUMMARYA routing method with dynamic channel selection in wireless sensor networks is an effective way to specify a route. It is different from communication between nodes in a common channel and is able to transmit data including attribute information. In this case, nodes located in the middle of a route use different channels, normal communication between nodes is temporarily interrupted, and throughput decreases as a result. For applications to be built by another wireless network, this method holds promise as an effective communication traffic–control method for situations such as emergency information that must be sent immediately. In this paper we propose a time‐division communication system that can give priority rights to data transmission including attribute information by adding a priority information component to the transmission data packet. This method has the rule that routers temporarily string together as relay nodes in the priority path, and other relay nodes not on the path pause while the priority path is active.
