Claim Text:
1. A method for routing in a multihop network, comprising, for at least one node of the multihop network, the following steps: a/ measuring a value of an intensity of an electromagnetic field over all of a frequency band, the electromagnetic field comprising signals attributable to messages transmitted in the multihop network and signals attributable to an electromagnetic environment of a neighborhood of the at least one node originating from outside the multihop network, said neighborhood comprising all nodes only one hop away from the at least one node, the frequency band comprising first frequencies relating to operating frequencies of the multihop network and second frequencies differing from said first frequencies, in the neighborhood of the at least one node, b/ determining, using a computer processor, a ratio between said measured value and a predefined maximum electromagnetic field threshold value over said frequency band, and c/ based on said ratio, selecting the at least one node as at least one routing node for at least one message in the multihop network so that the value of the intensity of the electromagnetic field at said at least one node does not exceed said predefined maximum electromagnetic field threshold value.
