How to use Erlang B to determine the blocking probability of packet loss in a wireless communication

Being in a digitally advancing era where wireless communication has been simplified due to plentiful radio technologies, traffic delay has increased during data transmission between these devices. Erlang B is an entity that is mainly used in a call center in measuring offered load like in switching materials. This article determines the rate of blocking during the communication process which is when a circuit group is fully occupied and cannot accept any more calls referred to as congestion, so they are either queued or lost. Impact of grade of Service for computer networks with benefits and drawbacks of each of this quality of service models in relation to the grade of services, illustrating basic approaches to Erlang B formula in an attempt to calculate blocking probabilities of packet loss for a group of identical parallel element. Our Calculations and results were tested and proofed with MATLAB.
