A cross layer fair resource allocation scheme for an OV-CDMA based optical network

Abstract

This paper addresses the problem of resource allocation for a multiclass time-slotted optical overlapped code-division multiple-access (OV-CDMA) network. A fair resource allocation (FRA) scheme is considered with the quality of service (QoS) requirements on both physical layer signal-to-interference ratio (SIR) and MAC layer average packet delay. A cross-layer approach in allocating the transmission power and rate for every class of users in the network is considered. It is shown that, although the FRA allocates the largest bandwidth under the R-ALOHA protocol, it forces the users to transmit with relatively higher power in comparison with the power required for the S-ALOHA and the R3T protocols.
