A new packet loss model of the IEEE 802.11g wireless network for multimedia communications

A wireless indoor network model coping with packet loss and packet arrival is proposed. This novel model is compared to the well known Gilberi-Elliott (GE) model. The proposed model is shown to be more accurate than GE in a particular but very representative IEEE 802.11g scenario. The proposed model has two parameters: one is a function of the source packet rate; and the other is almost constant. The extensive usage of the GE model in data communications is due to its simplicity. Likewise, it is expected a similar adoption of our model for wireless multimedia packet communications, since it was conceived based on traffic with multimedia features.
