Mobile Context Handoff in Distributed IEEE 802.11 Systems
The mobility management is one of the most critical issues in mobile wireless systems. In Mobile AP mobility support system, the context of each mobile station is defined by the association states between the mobile station and the wireless communication infrastructure. When the mobile station roams in Mobile AP systems, the context of the association follows the mobile station from one physical access point to another, thus eliminating the need for the mobile station to re-associate with new access points. The project will implement Mobile AP system in IEEE 802.11 systems, and the essential idea will be applicable in other wireless systems.

Real-Time Multimedia Steaming over Wireless Ad Hoc Networks

This project aims to transfer streaming multimedia data over a short range wireless networks, i.e. 802.11 (Wi-Fi) or Bluetooth. The project covers multiple clients, such as laptops, pocket PC computers, maybe even new-generation highly developed cell phones. On the other hand, servers can be desktop-laptop-pocket PC computers. Another significant point to mention is the status and location of servers; they can be located on the Internet, or two devices with wireless communication ability can be connected directly

Mobile Ad Hoc Networks (MANETs) and Development of Wireless Sensor Network Applications

This project will involve designing and constructing hardware and software components of an embedded sensor network infrastructure for developing and testing sensor applications. Real-world programming projects will be developed on this infrastructure. Click first  Click second ...  another course TinyOS  a course on Adhoc and Sensor Networks at Bilkent a course given by Jim Kurose  and other similar courses. The first real Sensor Network Application in our new Wireless Lab will be implemented using Crossbow Mote Sensor Kits. Sensors are running Tiny OS. Kits have PC compatible data acquisition boards. Experiments will involve both sensing and communications aspects of the sensor nodes. Algorithms implemented such as power efficient routing, border surveillance applications, etc. will be tested on the network.

Wireless Network Programming Projects

Bluetooth Enabled Interactive Game Development
In this project you will implement an interactive game (like Tic Tac Toe) using Bluetooth technology. You should implement a server and a client program communicating using bluetooth. The server will serve the game service and is able to play games with clients automatically or can initiate games between two clients. The server should be implemented such that it can serve many clients concurrently. The clients either can play game with the server or with another client. You will use Java API for Bluetooth Wireless Technology (JSR 82). If you implement the project for devices such as mobile phones you can use either MIDP 1.0 API or MIDP 2.0 API. In order to use JSR 82 you should have any device or simulator that supports following layers and generic profiles in the Bluetooth protocol stack: L2CAP, RFCOMM, SDP, Service Discovery Application Profile, and Serial Port Profile.

Bluetooth Browser
The Bluetooth browser should be able to browse and explore the technical specification of surrounding bluetooth devices. You can browse device bluetooth information and all supported profiles and service records on each device. This is a great utility tool to sniff bluetooth information as well as to validate your Bluetooth applications.

Waiter Assistant
The project is a full automation of waiter-cook interaction and intends to make the ordering process in a restaurant more organized and aims an increased utilization of waiters’ times. This project uses a server and a PALM client in order to get orders from the waiters and forward them to the relevant department of cooking. The order-owner waiter will be notified when the order gets ready. The main implementation technology is IEEE 802.11x but also bluetooth can be used.

Peer-to-Peer File Sharing Application for Bluetooth/802.11 Enabled Devices
This application will be able to download files from other mobile devices such as mobile phones. Using an application server, the application in the mobile phone will contact to the application server and receive the list of files available to be downloaded from other mobile phones. After this step, the process will continue with downloading the desired file from the destination. The implementation technology is Bluetooth or 802.11, but it may also include some parts that uses GSM and GPRS.

Wireless Touchpad
This project aims to use a pointer-events-capable mobile phone (like P800/P900) as a touchped which is found in laptops. The main aim is to get the pointer events in the mobile phone and port them via some wireless technology (like Bluetooth) to a normal PC, resulting the same events being fired again in the PC. If the mobile phone do not support IEEE 802.11x technologies, the project must be implemented using Bluetooth technologies.

Chat Application using Bluetooth
This project uses two bluetooth enabled devices, and these two mobile devices will be able to chat among each other. Whenever a new person having another device  comes into someone’s coverage area, all other users will be able to chat with him. This yields to intelligently forwarding messages from source to destination through the peers. Some algorithms, like ones used in routing may be implemented.

Weather Forecast Service Using WAP (Wireless Application Protocol) and WML (Wireless Markup Language)
In this project you will implement a WAP service that users can get forecast information of a specific place by providing necessary information. You can use any service providing forecast service by supplying data using XML. In the project either WAP 1.0 or WAP 2.0 can be used, and WML will be the main development language.

The server will get the information from the users and will query another service which provides weather forecast information as XML files. Then, it will process the XML file using a XML parser and prepare the data for WAP enabled devices. The client will use his/her cellular phone or PDA (Personel Digital Assistant) in order to access WAP service and view the results on his mobile devices as text or graphical data.

An SMS Application using Java Wireless Messaging API
Develop a wireless SMS application that uses the Java Wireless Messageing API (WMA). The application will send and receive SMS messages. The WMA is an optional package based on the Generic Connection Framework (GCF) and targets the Connected Limited Device Configuration (CLDC) as its lowest common denominator, meaning that it can extend both CLDC- and CDC-based profiles. It thus supports Java 2 Platform, Mobile Edition (J2ME) applications targeted at cell phones and other devices that can send and receive wireless messages.
