Fragments - The Internet Protocol Journal, Volume 11, No. 2


The Digital Ubiquitous Mobile Broadband OLSR (DUMBO) project deploys mobile wireless networks on an ad hoc basis for emergency conditions, such as after a natural disaster when a fixed network infrastructure is not available.

A Mobile ad hoc Network (MANET) consists of mobile nodes that automatically cooperate to support the exchange of information through wireless medium. Since the MANET does not rely on fixed telecommunication infrastructure, it is suitable for emergency situations and can be set up in a short amount of time. Using lightweight portable mobile nodes, MANET coverage can penetrate deep into areas not easily accessible by roads or into areas where the telecommunication infrastructure has been destroyed.

DUMBO allows streaming video, Voice over IP (VoIP) and short messages to be simultaneously transmitted from a number of mobile laptops to a central command center, or to the other rescuers at the same or different disaster sites. The DUMBO command center has a face recognition module that identifies potential matches between unknown victims' face photos taken from the field and a collection of stored known face images. In addition, sensors can be deployed to measure environmental data such as temperature and humidity. Data from the sensors can be sent to the command center which analyzes or passes it on to the other mobile nodes. The command center can be located either in the disaster area or anywhere with Internet access. DUMBO technology is currently being deployed in cyclone-ravaged Burma. See and
