According to an embodiment there is provided a wireless device comprising a processor and memory storing. The memory stores executable instructions and rules defining benefits to be received by wireless devices and costs incurred by the wireless devices when the wireless devices participate in data transfer in a network. The instructions, when executed by the processor, cause the device to store, if the wireless device forms part of a network comprising other wireless device and a backbone, information detailing the topology of the network and/or the status of other devices of this network, based on the rules and the topology information estimate the costs and/or benefits of transmitting data to the backbone via other wireless devices of the network and based on the rules estimate the costs and/or benefits of transmitting data directly to the backbone. One or both estimates combine an estimation of the technical costs of data transmission, their compensation payments and path length dependent network benefits. The instructions, when executed by the processor, further cause the device to determine whether the costs and/or benefits of a direct exchange with the backbone outweigh those of data exchange with the backbone via other nodes. |
