A Simulation Environment for Enhanced UMTS Performance Evaluation

The paper proposes a new simulator that supports UMTS and Enhanced-UMTS performance evaluation. Existing UMTS simulators integrate linklevel and system-level simulators, implemented using time-based simulation techniques. The proposed simulator integrates time-based link level simulations into an event-based system level simulator by extending ns-2. The simulator can evaluate parameters associa...

NS-2 enhancements for detailed HSDPA simulations

The Enhanced UMTS Radio Access Network Extensions (EURANE) provided UMTS and HSDPA support in the Network Simulator (NS-2). The main components of EURANE include the Radio Link Control (RLC) layer with the Acknowledged and Unacknowledged Modes, MAC layer for the main UMTS and HSDPA transport channels and a physical-layer simulation tool for simulating the fast channel variations in HSDPA. Altho...

Network-Level Simulation Results of Fair Channel-Dependent Scheduling in Enhanced UMTS

In this paper, previously performed UMTS studies have been extended to enhanced UMTS, and combined with several scheduling algorithms (ref. [1,2]). Scheduling algorithms for W-CDMA systems ranging from C/I based scheduling to Round-Robin scheduling are presented and discussed. We also include a trade-off between these two extreme methods of scheduling: Fair channel-dependent scheduling. All the...

An Efficient Mechanism for UMTS Multicast Routing

In this paper, we present a novel scheme for the multicast transmission of data over Universal Mobile Telecommunications System (UMTS) networks. Apart from the normal multicast transmission over UMTS, we consider the handling of exceptional cases caused by user mobility scenarios. The proposed scheme is in accordance with the current specifications of the Multimedia Multicast/ Broadcast Service...
