Abstract
There is provided a wireless device and a method for managing a wireless device for wireless transmission over a multi-hop wireless network, the wireless device comprising a wireless interface and a controller. A schedule of timeslots for transmitting and timeslots for receiving messages is determined based on which layer of the network the wireless device occupies. A transmission from a first node is received during a scheduled timeslot for receiving messages, the transmission comprising a message. The message is added to a queue of messages. In response to a signal being received via the wireless interface indicating that another node in the network has received the message, the message is removed from the queue of messages. During a scheduled timeslot for transmitting messages, at least one message from the queue of messages is transmitted to nodes in a layer closer to the sink than the wireless device.
