Sample text

The modelled call center is one with skill based routing, which is realized as follows. As long as there are free agents in the group ST , clients from the queue QT are directed to them – as is the case of SB and QB , respectively. When there are clients in QT and there are no free agents in ST , the clients are directed to agents from STB ; similarly for QB and SB . So the constraints for the elements of the system state (nT (t), nB (t), nTB (t)) are (we omit t for clarity): ⎧ ⎧ ⎨ nTB = sTB ⎨ nTB ∈ [0, sTB − 1] or (2) nT ∈ [0, sT ] nT ∈ [0, sT + qT ] .

This is the quotient of a number of delivered data packets to all packets received by receivers. It is the ratio of the effectiveness of the protocol. 2. Ratio of Data Forwarding Efficiency. This is the number of data packet transmissions per delivered packet. This measure takes into consideration the number of discarded and retransmitted packets. In the case of our protocol this measure is less than 1. 3. Ratio of the Number of Sent Bytes in Controlling Packets to the Number of Data Bytes Received by Receivers.
