A new bandwidth statistical multiplexing scheme for 2D WLAN environments with passive reservations

The last studies about telecommunications and computer-science have increased the need and the availability of communication devices, such as laptops and palmtops; at the same time, the research in digital wireless communications has made possible the connection of notebooks to Internet wherever they are. Providing adequate quality of service is a very important issue in wireless communications, because of the heavy impact of userspsila mobility, especially when mobile nodes move among different coverage areas. In this paper a novel 2D passive reservation scheme for WLAN environment is presented: the cell stay time distribution is analyzed under the smooth random mobility model in terms of mean and standard deviation; then, a new prediction technique is proposed as an enhancement of previous mobility independent predictive (MIP) pre-reservation schemes, that led to an acceptable service degradation with very low system utilization. With the help of the CST statistical multiplexing introduced in this paper, better results are obtained in terms of higher system utilization, maintaining the quality of service and prediction error at acceptable levels. The proposed idea has been validated through many simulation campaigns, with a good performance analysis in terms of bandwidth utilization, prediction errors and other interesting parameters.
