Abstract
In this paper, we develop a fair resource allocation scheme for a multiclass
time-slotted optical overlapped code-division multiple-access (OV-CDMA) network. The
resource management scheme is fair in the sense that the users have their power and rate
allotted according to their quality of service (QoS) requirements. In addition, no class
of users can dominate over the other classes. A unified framework for the resource
controlling scheme is proposed. It consists of simply finding a single control parameter
based on which the optimal transmission rate and power are obtained for every class of
users. Analytical results show that the maximum transmission rate for a given class of
users is only achievable when the users in that class are transmitting with the highest
possible laser transmission power. In addition, we have demonstrated that the optimal
transmission rates can be obtained via the solution of the rate characteristic
polynomial. It is shown that our proposed scheme provides a substantial improvement in
the system capacity while preserving the required fairness criteria.
