Study of Various TDMA Schemes for Wireless Networks in thepresence of
نویسنده
چکیده
The objective of this paper is to determine the minimum system dropping rate (or, equivalently , dropping probability) induced by TDMA schemes supporting time-constrained applications with common maximum cell delay tolerance. Expressions are derived for the induced system dropping rate for various TDMA schemes with diierent overhead and the maximum number of users than can be admitted in the network without violating the maximum dropping rate constrain is determined. Based on these derivations, the optimal (or of largest \capacity") TDMA scheme-among those considered-is determined. The performance limiting factors associated with the suboptimal schemes are identiied, and the magnitude of their (negative) impact is evaluated. Based on this information it is possible to point to performance improving modiications which should be pursued to the extend permitted by technological constraints.
