Abstract [en]

NOVELTY - The multichannel characteristics of the wireless links between network nodes such as mobile station, are estimated based on explicit channel matrix estimation and number of transmit and receive antennas used by the node for multiple channel provision. The link cost is determined for the link based on the determined characteristics. USE - For determining link cost of network nodes such as mobile station and base station, used for routing in partially wireless multi-hop network e.g. ad-hoc multi-hop network and fully wireless multi-hop network such as adaptive beam-forming network or multiple input multiple output (MIMO) network and also for multi-hopping in cellular communication system. ADVANTAGE - Route selection in wireless multi-hop network is improved using enhanced routing metrics. High throughput, reduced delay or high network load operation is achieved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) method of link-cost based route determination; (2) method of link-cost based routing of data; (3) arrangement for determining link cost ; (4) arrangement for link-cost based route determination; and (5) arrangement for link-cost based routing of data. DESCRIPTION OF DRAWING(S) - The figure shows the flowchart of data routing process including link cost determination and route determination.
