Claim Text:
1. A method for discovering routes to forward data packets from source nodes (sources) to sink nodes (sinks) in a wireless network, wherein some neighboring sources act as relay nodes, comprising the steps of: measuring in each source, a rate of receiving control messages from each neighboring node, wherein the rate of receiving control messages (SI wherein C DIO M is a number of Destination Oriented Directed Acyclic Graph (DODAG) Information Object (DIO) messages received from the neighboring node M, and C DAO M is a number of destination advertisement object (DAO) messages received from the neighboring node M, C DIS M is a number of DODAG Information Solicitation (DIS) messages received from the neighboring node M, and wherein W DIS , W DIO and W DAO are non-negative weights; and forwarding the data packets from a particular source to a particular sink via the neighboring node having the lowest rate of receiving control messages.
