Abstract

In Next Generation Networks (NGN) a variety of services with different requirements, like real time communications, broadband Internet access, email services are expected. Consequently, Packet Scheduling mechanisms and Resource Allocation techniques for Quality of Service (QoS) guarantees will play a key role. This paper proposes two resource allocation strategies for a CDMA satellite return link, based on a Orthogonal Variable Spreading Factor (OVSF) codes with Earliest Deadline First policy (also referred to as Single Code CDMA) and Multi-Code with Generalized Processor Sharing policy (also referred to as Multi Code CDMA), respectively. Moreover a Minimum Power Allocation algorithm is implemented in order to maximize system capacity and guarantee Bit Error Rate (BER) requirements. An avionic environment has been taken as reference scenario and it is referred to as AirCom. The effectiveness of the two proposed algorithms for such a scenario is evaluated by means of software simulations using OPNET modeler. The work presented in this paper has been partially inserted in the framework of EU NATACHA project. © 2005 IEEE.
