Simulation of optical network operation using simulator ns-2

Simulation of 802.21 Handovers Using ns-2

The new IEEE 802.21 standard specifies link layer intelligence and other related network information to upper layers in order to optimize handovers between networks of different types, such as WiMAX, Wi-Fi, and 3GPP. This paper makes a short description of 802.21 standard, how it is implemented in ns-2, and the signaling used in a handover between WiMAX and Wi-Fi. The paper also proposes a nove...

Network Emulation in the Vint/NS Simulator

Employing an emulation capability in network simulation provides the ability for real-world traffic to interact with a simulation. The benefits of emulation include the ability to expose experimental algorithms and protocols to live traffic loads, and to test real-world protocol implementations against repeatable interference generated in simulation. This paper describes the design and implemen...

Performance Comparison of Reliable Multicast Protocols using the Network Simulator ns-2

Reliable multicast protocols on top of the MBone are presently subject to intensive research. In the past, numerous protocols have been developed and their respective performance been analysed. Little progress has been made, though, to compare different approaches. In this paper, we use the network simulator ns-2 to evaluate the performance of three protocols, namely Scalable Reliable Multicast...

Performance Modeling of TCP and UDP over Packet Radio Networks using the ns-2 Network Simulator

Live network tests are often used to obtain performance metrics associated with the transmission of data using TCP and UDP over packet radio networks. However, only individuals who hold an amateur radio license issued by the United States Federal Communications Commission, as specified by Title 47, Code of Federal Regulations, Part 97, are permitted to operate an amateur station. For this reaso...
