Abstract:
1. A method of determining link cost for routing in an at least partially wireless multihop network, said method comprising the steps of: estimating, for a wireless link between a pair of network nodes where at least one of the nodes is configured for operation with multiple antennas to provide for multiple channels, multi-channel characteristics between the nodes including an M×N dimensional complex channel gain vector or matrix H where h determining link cost for said wireless link based on the estimated multi-channel characteristics including said M×N dimensional complex channel gain vector or matrix H where the average rate for a link from node v where B is the bandwidth, which may be neglected if only one common bandwidth is used in the whole system, E{ . . . } is an optional expectation value, Det{ . . . } is the determinant, I
