Abstract
A method of avoiding a channel interference in a single channel sensor network, includes periodically measuring an energy of a channel used by at least one node included in the sensor network; exchanging the measured energy of the channel with a neighbor node of the at least one node; receiving energy of all nodes of the sensor network and determining if there is an interference, by a coordinator node, which is a highest node of the at least one node; and when it is determined that there is an interference, switching a channel influenced by the interference to a channel which has been scanned by the coordinator node and is not influenced by the interference, thereby avoiding an influence of the interference.
