Mobile IP versus IPsec Tunneling with MOBIKE: A Comparison Under Wireless Vertical Handover

Presentation slides and final report (PDF files).

Abstract:
Mobile devices are increasingly including support for multiple heterogeneous wireless networks like 3G cellular, 4G, and IEEE 802.11. When a mobile device attaches to a network, it typically obtains a temporary IP address allocated by the network provider. One approach to provide a permanent IP address to a mobile devices is Mobile IP (RFC 3344). Mobile IP has some objectionable aspects: it often requires network provider support, and it can drop data during vertical handover. IPsec tunnelling with IKEv2 Mobility and Multihoming Protocol (MOBIKE) (RFC-4555) may be used as an alternative to Mobile IP. IPSec tunnels do not require any special support from the network provider. Because it supports multi-homing, MOBIKE can provide make-before-break operation at inter-network handover, eliminating any service interruption during vertical handover.

This project provides an ns-2 simulation of mobile data applications transitioning across two different wireless networks, comparing the Mobile IP and MOBIKE vertical handover strategies.

Comparison of WiMAX and ADSL By Streaming Video Content using OPNET v.16
Comparison of WiMAX and ADSL By Streaming Video Content using OPNET v.16

Presentation slides, demo slides, and final report (PDF files).

Abstract:
The IEEE 802.16 standard is known as WiMAX (Worldwide Interoperability for Microwave Access). Now a day this protocol is widely used for fixed and mobile Internet access. WiMAX provides a theoretical maximum data rate of 75 Mbps. On the other hand, Asymmetric Digital Subscriber Line (ADSL) embodies the RFC 2662 is widely used connection and provides guaranteed service. However characteristics of ADSL limit the even distribution of fixed broadband services. WiMAX has surfaced to substitute ADSL, which is designed to provide high-speed Internet access to a wide range of devices such as laptops, cell phones, cameras, music players, etc. which are being used by clients over the last mile. For this project, we plan to use OPNET version 16 to simulate streaming video content over WiMAX and ADSL. We will examine four performance factors: Packet loss, Delay, Jitter, and Throughput while streaming video content subscribers to determine whether WiMAX can give performance comparable to ADSL for Video application.

Coordination of Mobile WiMax(802.16E) with WiFi technology

Presentation slides, demo slides, and final report (PDF files).

Abstract:
IEEE802.16e (Mobile WiMAX) standard is proposed to support mobility, handover has become one of the most important Quality of Service (QoS) factors. Applications like mobile Voice over Internet Protocol (VoIP), multimedia gaming greatly benefits from low-latency. To maintain such low-latency and keeping high QoS various advanced handover schemes are being proposed and developed.The hybrid networks of Wi-Fi and WiMAX can provide high data rate and enhanced multimedia services, but it is challenging to obtain optimized handover decision based dynamic QoS information.

The first goal of this project is to implement various techniques used for handover in mobile Wimax technology and compare the performance of such techniques in different physical channel environment.The second stage of this project is to implement and simulate the handover techniques from WiMax to WiFi without degradation in the QoS i.e. maintaining the connectivity of the MS (mobile station) to either base station.

The third stage is the coordination of both technologies at the same time i.e. keeping the MS (mobile station) connected to both technologies so that the SS (subscriber station) feels the huge bandwidth available when both technologies are simultaneously available. We will divide this project into 3 phases so we can build and model our system in the right way for easy debugging. However, our first goal is to accomplish the first stage, and as time permits we will continue the other phases. We intend to complete our model with a full documentation as an open source for interested students.

OSPF, EIGRP and RIP Peformance Analysis Based on OPNET

Presentation slides and final report (PDF files).

Abstract:
Routing protocol is the key for the quality of modern communication network. EIGRP, OSPF and RIP are the dynamic routing protocols being used in the practical networks to propagate network topology information to the neighboring routers. There have been a large number of static and dynamic routing protocols available but choice of the right protocol for routing is dependent on many parameters critical being network convergence time, scalability, memory and CPU requirements, security and bandwidth requirement etc. This project uses OPNET simulation tool to analyze the performance of OSPF,EIGRP and RIP commonly used in IP network today. According designed simulation experiment scenarios, compare the difference between OSPE,EIGRP and RIP routing protocols.

Modeling and Simulating STP vs RSTP on various network topologies

Presentation_slides and final report (PDF files).

Abstract:
With the increasing demand of high speed LANs, the probability of attaching two layer-2 (link layer) devices together increases and this creates a switching loop. This switching loop broadcasts the frames to all the ports and since there is no TTL (time to live) attached to the layer-2, these packets circulate in the loop endlessly, thereby, bringing the whole network down. To avoid switching loops, IEEE 802.1d protocol defines the STP (spanning tree protocol) and IEEE 802.1w protocol enhances the STP into RSTP (Rapid STP). This project will model and simulate a network that creates the switching loop and then implements STP/RSTP on various network topologies such as ring, mesh, star etc. Recovery times from the switching loop and the bandwidth latency will be measured for the topologies.

Analysis of Mobile IP in Wireless LANs

Presentation slides, demo slides, and final report (PDF files).

Abstract:
The purpose of this project is to show how MIPv4 works in wireless lan networks.We will show how it can be simulated in both OPNET and ns-2 simulators and We want to show the advantage of MIP when our mobile node roams between different networks without losing its IP connectivity.It means with MIP, the application doesn't need to be restarted and roaming will be transparent for the user.In general speaking MIP provides an efficient, scalable way for roaming in internet.Since the OPNET modeler can not show the tunneling data between home agnet and foreign agent routers when we use mobile work station node and it uses mobile subnet to show how MIP works, we decided to use ns-2 to show how a real mobile node moves between different subnets and it uses MIP to keep its home IP connectivity.

Abstract:
The Wireless LAN (WLAN) has gradually become a popular internet access method. It is more conven ient comparing to the wired Ethernet or other access network. However due to the different chara cteristics of the different physical layer (media) ? the WLAN is a technology based on the wirel ess media ( FH, DS, IR), the MAC layer (802.11) of the WLAN has introduced some unique technolo gies (CSMA/CA) which isn't used by the Ethernet (802.3, CSMA/CD), In this project we will use OP NET to evaluate the performance of some of these technologies such as RTS/CTS ? a mechanism to a void Hidden Nodes, Fragmentation - a mechanism to improve the throughput by avoiding retransmi ssion of large block of data, Exponential back-off algorithm ? a mechanism to avoid collision.
