AVOIDING BROKEN LINKS IN SMART METER NETWORKS FOR LOOP-FREE ROUTING OF PACKETS

摘要

This invention relates generally to routing of packets in wireless sensor networks, and particularly to routing packets in smart meter networks with broken links. Broken links in the sensor network are avoided by representing the network as a DODAG. A rank associated with each node defines a position of each node relative to other nodes, and the rank is in a form of a proper fraction, and the rank of each node never increases to enable loop-free routing.
