Wireless Communication Lab

Overview

The Wireless Communication Lab investigates efficient ways to form a secure extended ad-hoc network of laptops, handhelds, and other wireless capable devices, and bridge it to the Internet. Our research encompasses scalable routing, security, and energy efficiency in pure peer-to-peer mobile ad-hoc networks, mobile multi-hop infrastructure access networks, and sensor networks.

Research Projects

The Mobile Ad hoc Network Visualization Project
The the Mobile Ad hoc Network Visualization Project was created to enable researchers to visualize the link dynamics in a MANET. In a wireless network, the connectivity between nodes is continuously changing. This is true in both fixed and mobile networks. The Wave Relay Mobile Ad hoc Networking System is currently deployed in Baltimore City in the vicinity of the Johns Hopkins Homewood Campus and provides the real-time link connectivity information for this visualization project. Information from the Wave Relay system is continuously transmitted to a server at JHU. The collected information can then be displayed in Google Earth. The statistics are refreshed once per second providing near real-time monitoring of the mobile ad hoc network. The current system contains both fixed and mobile nodes. The mobile nodes are part of our JHU Wireless Shuttle Bus Project..

The JHU Wireless Shuttle Bus Project
The Wireless Shuttle Bus Project is the result of a collaboration between the JHU Wireless Communication Lab, the JHU Security Dept. and the Homewood Parking Office. The project involves the deployment of the Wave Relay Ad hoc Networking System on the JHU Escort Shuttle Service and the Homewood Campus Parking Shuttles. This provides the JHU Security Dept. with the ability to track the speed and location of the escort shuttles in real-time. In addition students on the shuttles buses are able to obtain wireless Internet access. The shuttle deployment also serves as a test-bed for evaluating the performance of MANET routing protocols.

Wave Relay Ad hoc Networking Test-bed
This project focuses on the development of the Wave Relay ad hoc networking test-bed here at the JHU campus. Currently, more then 50 wireless routers have been deployed across the Homewood Campus. The wireless network serves as a research platform for evaluating protocol performance. The goal of the Wave Relay project is to build a large scale ad hoc network across the Johns Hopkins University campus and surrounding neighborhoods. Our goal is to incorporate mobile applications and explore the effects of mobile access on network performance.

Secure Ad Hoc Networking for Industrial Process Control
This project explores the integration of wireless communication systems into industrial process control. Through collaboration with industry experts, industrial plants, and control system manufacturers, we attempt to determine industry requirements and incorporate these requirements into protocol design.

Classes

600.647 - Advanced Topics in Wireless Networks
This class will survey current research in wireless communication networks. These types of networks have been growing exponentially in the past several years and include a host of different network types: ad hoc, cell phone, access point, sensor, etc. The class will build understanding of all layers of wireless networking and the interactions between them (including: physical, data link, medium access control, routing, transport, and application). The topics of security, energy efficiency, mobility, scalability, and their unique characteristics in wireless networks will be discussed.
