METHOD FOR PRESELECTING A ROUTER IN AN RPL NETWORK

摘要

A method for preselecting a router in a LLN (Lower power and Lossy Network) network from a plurality of nodes in which each router node transmits to the other router nodes of the LLN network within direct radio range of the router node an announcement message, and, upon receiving the announcement message, each of the other router nodes compares its current status with respect to a router node with the status indicated in the announcement message, and configures its status depending on the comparison so that a single node from among the nodes of the LLN network within direct radio range of the router node transmits to the root node a configuration request MER_Request as a multicast router for data from or intended for the host node.
