Abstract :
In multihop wireless networks each node is equipped with multiple radio interfaces, and multiple channels are available for communication. One of the major problems in such networks is the capacity reduction due to the interference among multiple simultaneous transmissions. In order to effectively minimize interference, this paper proposes a QoS routing protocol CATR based on channel assignment and timeslot reservation. When routing, CATR selects a path and assigns channels dynamically to each link of the path with the QoS guarantees at the same time.
