Abstract: A relay node is configured to discover a route between a route origination node and a route destination node in a mesh communication network. The relay node in this regard generates a route request message that requests a route from the route origination node through the mesh communication network to the route destination node. The relay node transmits the route request message via unicast or broadcast, depending respectively on whether a routing table at the relay node has or does not have an entry indicating a known route to the route destination node.

Abstract: A node (100) is configured for use in a communication network. The node (100) is configured to obtain a message with a source address and a destination address. The node (100) is also configured to determine whether the message is a type of message that is sent in response to a different message routed from the destination address to the source address, and whether a forward route (16) from the destination address to the source address has been established. The node (100) is also configured to selectively transmit the message on a backward route (18) that is the reverse of the forward route (16), depending on the determining.

Abstract: A responding device (14) is configured to transmit messages at transmission opportunity times that occur substantially periodically according to a transmission interval. Configured in this way, the responding device (14) receives a request message (16) from a requesting device (12) in a wireless communication system (10). Responsive to the request message (16), the responding device (14) determines to transmit a response message (18) at a response time that is distinct from any of the transmission opportunity times and that occurs after at least the transmission interval has passed since receiving the request message (16). The responding device (14) in this regard delays transmission of the response message (18) until the response time, by refraining from transmitting the response message (18) at one or more transmission opportunity times that occur after receiving the request message (16) but before the response time. The responding device (14) then transmits the response message (18) at the response time.

Abstract: A master device 103 and a method for transmitting a message towards a destination node. The master and the destination are operating in a network 100. The master has a Slave Neighbour Table (SNT) and a Master Neighbour Table (MNT). When the identity of the destination is comprised in the SNT, the master unicasts the message to the slave having the same identity as the destination, otherwise the master determines if the identity of the destination is in the MNT. If so, the master unicasts the message to the neighbour master having the same identity as the destination or to the neighbour master being the master of the neighbour slave having the same identity as the destination; otherwise the master multicasts the message to all neighbour masters comprised in the MNT. When the identity is neither comprised in the SNT nor in the MNT, the master broadcasts the message.
