FIELD: radio engineering, communication.SUBSTANCE: in the method for estimation of residual bandwidth, which is the subject of the invention, network activity is measured and relevant statistics on network operation are obtained by exploiting the wireless nodes' inherent capability (originating from the nature of 802.11 protocol) of receiving/overhearing DATA-ACK messages transmitted on a radio channel but not destined for said nodes. In the presented method, wireless link residual bandwidth is calculated using analytical estimation techniques. When the residual bandwidth is estimated as a result of these calculations, it is possible to make more efficient routing decisions based on bandwidth (for example the link with higher residual bandwidth should be favoured in routing decisions) and/or to have availability prediction for the flow connection establishment control process (for example accept a new flow only if there is enough available route residual bandwidth).EFFECT: high accuracy of estimating traffic handling capacity.8 cl, 1 dwg |
