Method for transmitting data from a resource-constrained transmitter to a receiver in a wireless network, comprising the following steps: -the resource-constrained transmitter (21a, 21b, 21c) sending a channel request message to the receiver, -in response to the request, the receiver (22) determining communication channel availability based on the result of a sensing step and broadcasting channel information, -the resource-constrained transmitter (21a,21b, 21c) listening to the information and transmitting data on the corresponding channel, wherein the sensing step is performed by the receiver before or after receiving channel request from the transmitter. The invention also relates to a wireless network. |
