Abstract:
1. A method for admission control of connections made up of one or several flows to a shared wireless medium, each connection requiring a predetermined target application Protocol Data Unit (PDU) error rate (ε i ) and at least an additional quality of service requirement (D i ; T i ), a transmission on the shared wireless medium being adapted for transmitting frames (LF; SF) of a predetermined maximum size (L; S), with a data link layer mean error rate (BER), the method comprising: applying criteria for new connections to determine whether resources can be provided for a respective connection, said criteria include the steps: calculating a number (R) of retransmissions of frames (LF; SF) which are needed in order to reach the target application PDU error rate (ε the target application PDU error rate (ε a data link layer mean error rate (BER); and the maximum size (L; S) of the transmitted frames (LF; SF); calculating an achievable quality of service parameter (D′ determining if resources can be provided for the connection depending on the achievable quality of service parameter (D′
