There is a method including receiving, at a first network node, information from a relay node associated with the first network node. The information includes an indication of at least one second network node neighboring the first network node. Parameter information of the at least one second network node is determined on the basis of the indication. The parameter information is uniquely mapped to the relay node and indicates current available resources of the at least one second network node for the relay node. Apparatus and computer program products are also disclosed.

A wireless communication device transmits data to a relay destination being one of first relaying devices capable of communicating out of relaying devices; obtains first information, from each first relaying device, that indicates a representative value of remaining operating times of relaying devices present on a relay route from the first relaying device to a target device; determines to perform a new route search, based on the first information; increases a transmission power; then transmits a request; receive responses from all or a part of second relaying devices, which are relaying devices that have received the request, including pieces of second information each of which indicates a representative value of remaining operating times of relaying devices present on a relay route from the second relaying device to the target device; and selects a relay destination of data from among the second relaying devices based on the pieces of second information.

A method, system, or computer program product to enhance the performance of multi-hop cellular networks or other wireless networks is provided. A wireless device (e.g., cellular telephone) is able to communicate with a base-station in a cell of the cellular network over a non-cellular interface via another wireless device in the cell through the use of multi-hopping. By enabling wireless devices to communicate with a base station in such a manner, the effective coverage area of the cellular network is expanded and the effective capacity of the cellular network is improved. Distributed routing, device management, adaptive scheduling, and distributed algorithms can be used to enhance the overall performance of multi-hop cellular networks.

Embodiments herein relate to a method in a relay node (10) for acquiring information about a type of a radio network connection between a donor radio base station (12) and a radio base station (14). The relay node (10) and the donor radio base station (12) are comprised in a radio communications network and the donor radio base station (12) is serving the relay node (10). The relay node (10) receives a message from the donor radio base station (12), which message is indicating a type of radio network application protocol, which type is related to a type of the radio network connection between the donor radio base station (12) and the radio base station (14). The relay node (10) determines the type of the radio network connection based on the type of radio network application protocol indicated in the message. The relay node (10) also stores the type of radio network connection in relation to the radio base station (14) for selecting the type of radio network connection when later communicating with the radio base station (14).
