A method of communication between a first, a second and a third node in a wireless multi-hop network (A, B, C), the method comprising bringing the first node and the second node respectively the third node in a fully operative mode for communication with each other and subsequently bringing the first node and the second node respectively the third note in a reduced operative mode where no communication with any other node is possible, wherein the method furthermore comprises: before bringing the respective node (A, B, C) in the fully operative mode, bringing the second node in a listening mode during a token listening period to check for presence of a wake-up token, bringing the respective node (A, B, C) into the reduced operative mode if no wake-up token is received, and bringing the respective node (A, B, C) into the fully operative mode for reception of data if a wake-up token is received, and wherein the method furthermore comprises synchronizing the timing of the listening mode of the respective node (A, B, C) with the timing of the transmitting of the wake-up tokens by another node, wherein synchronizing includes one node transmitting a beacon signal and another node synchronizing with the beacon signal, wherein collisions of the wake-up tokens are reduced by using a collision avoidance scheme according to which the third node intending to send a wake-up token to the second node, having received a wake-up token sent from the first node to the second node cancels the wake-up token to the second node as a consequence of having received the wake-up token addressed to the second node, and respectively scheduling a first, second and third time slot selected among different time slots in a beacon period between two subsequent signals, respectively allocating the token listening period of the second node to the first time slot, the token listening period of the third node to the second time slot and the token listening period of the first node to the third time slot. before bringing the respective node (A, B, C) in the fully operative mode, bringing the second node in a listening mode during a token listening period to check for presence of a wake-up token, bringing the respective node (A, B, C) into the reduced operative mode if no wake-up token is received, and bringing the respective node (A, B, C) into the fully operative mode for reception of data if a wake-up token is received, and wherein the method furthermore comprises synchronizing the timing of the listening mode of the respective node (A, B, C) with the timing of the transmitting of the wake-up tokens by another node, wherein synchronizing includes one node transmitting a beacon signal and another node synchronizing with the beacon signal, wherein collisions of the wake-up tokens are reduced by using a collision avoidance scheme according to which the third node intending to send a wake-up token to the second node, having received a wake-up token sent from the first node to the second node cancels the wake-up token to the second node as a consequence of having received the wake-up token addressed to the second node, and respectively scheduling a first, second and third time slot selected among different time slots in a beacon period between two subsequent signals, respectively allocating the token listening period of the second node to the first time slot, the token listening period of the third node to the second time slot and the token listening period of the first node to the third time slot.
