• PROJECT 1:  A Wireless Sensor Network Using MOTE-KIT5040CC.

Developing a wireless sensor network using MOTE-KIT5040CC (900 MHz) kit. The objective is to set up an Ad-Hoc WLAN that consists of a number of Motes, each has a wireless card with some acceleration sensor, that operates as a mobile server. The client is set up on a PC with a standard  MOTE-KIT5040CC access point to route messages from the client to the server. The client is operated by using a GUI to allow the user to issue some commands to the server like streaming sensor data from the a given server node to the client in addition to displaying the streamed data for the user. The client request is routed to the client motes.  The student will develop both of the client program and distributed sever program. The hardware is available with the instructor. The deliverables are the client and server programs and the performance measure of the distributed sever such as the timing of the requests and quality of service.

• PROJECT 2: Simulation and evaluation of CSMA/CA

  Simulation and evaluation of an  IEEE802.11 network. Assume an IEEE802.11 wireless LAN setting with one access point and N (variable) terminals on the ground.  It is required to model the collision-based scheme supported by the LAN.  For a given arrival process of traffic, evaluate the performance of the LAN in terms of terminal throughput, network throughput, and traffic delay (for each type). The simulation should operated using a GUI to input relevant data and display results

• PROJECT 3: Developing a WLAN using Stargate embedded system. The objective is to set up an Ad-Hoc WLAN that consists of a number of stargate embedded computer, each has a wireless card with some hetero-genous resource, that operate as a mobile server. The client is set up on a PC to which one of the stargate modules is used as an access point to route messages from the client program to the server. The Stargate near the PC is to be configured as a gateway between wired LAN and wireless LAN and vice versa. Network settings at each computer are to be configured through boot-up configuration scripts. The wireless communication between Stargate computers and with the Host PC is to be performed using TCP socket programming in Java. The client is operated by using a GUI to allow the user to issue some commands to the server like streaming video or other sensor data. The client message is routed to the client system where it is analyzed based on the available resource and power of each module. The student will develop both of the client program and distributed sever program while ensuring that the WLAN server should provide means of communication among the modules to better serve the request from the client. Prior knowledge of Java is needed. The hardware is available with the instructor. The deliverables are the client and server programs and the performance measure of the distributed sever such as the timing of the requests and quality of service.

• PROJECT 4: Simulation and evaluation of IEEE802.11 network support for real-time services. Assume an IEEE802.11 wireless LAN setting with one access point and N (variable) terminals on the ground. The terminals generate real-time traffic such as voice and utilize the polling mechanism to transport this traffic. Write a code to simulate such network. Produce results such as terminal throughput, network throughput, average delay for payloads, drop rate, etc. (from Dr. Ashraf Mahmoud).

• PROJECT 5: TCP/IP window and slow-start study over wireless channels. Assume two nodes are communicating using TCP/IP. The TCP initializes a transmission window and starts sending sequenced segments. The window size increases as the session progresses increasing the utilization of the link. When congestion is occurring (lost segments or their acknowledgments) the TCP reduces the window size to reduce outgoing traffic. This leads to lower utilization of the link. After some time of no data loss, TCP increases the window size again to increase the link utilization and so on. For wireless links, packets may be lost due to errors and not necessarily due to congestion and buffer overflow. Write a simulation code that emulates this process. Determine the actual parameters used in current TCP/IP based transport. For a given arrival process of segments at the source nodes, and a given error model on the wireless link, find the average throughput of the wireless link and the average segment delay (from Dr. Ashraf Mahmoud)

• PROJECT 6:   Developing a Reliable Peer-to-Peer protocol for WLAN using the Stargate embedded system. The stargate embedded system consists of 8 stargate embedded processors each has a 500 MHz Xscale processor with a wireless communication card. The system is intended to work as WLAN where one module (connected to a PC) serves as an access point to the VLAN. The objective of the project is to develop a Reliable Peer-to-Peer protocol (RPTP). In this case, the RPTP consists of two main threads (1) a communication thread (TC), and (2) a processing thread (TP). TC permanently listen the WLAN to capture any communication initialed by one of its peers. On arrival of packet, TC extract its data and activates data-update thread (DUT) which updates the state variables in the local memory of this module. Note that thread DUP is activated only if there is an arriving packet. TP normally examines the state variables and may decide to broadcast some action to its peer modules. For this TP posts the data to be broadcasted in a specific buffer so that TC can perform the broadcast whenever possible, i.e. all communications are carried out by TC. The student is expected to participate (with an RA) in developing a testbed system which allows modules to run TC and TP, in addition to the generation of broadcast request within TP. To study reliability, each module is to record packet identifiers for each arriving packet as part of the TC thread in addition to the total time needed to complete a customized broadcast with potentially some acknowledgement. This might require investigation of a customized UDP protocol or an imperative Poll-based communication (like in SNMP). The uploaded data from the modules will serve determining the degree of reliability of the used protocol.
