style="mso-bidi-font-style:normal">Ad-hoc</i> NETworks
(MANET) under challenging application requirements. <br>
These arise in hostile environments where traditional
network-design principles do not apply. Such <br>
scenarios may include broadcast voice and streaming data
(video) services in military deployments, <br>
public-safety responder operations to emergencies, relief
missions in natural-disaster areas, and so on. <br>
In all such cases, the point-to-point ground communication
channels are very brittle due to mobility,
<br>
obstacles, and the lack of a controlling infrastructure.
The focus will be on the main objectives and <br>
constraints in designing the necessary networking and
control mechanisms for a MANET to achieve <br>
the abovementioned targets. We will also present a simple,
autonomous, cooperative-transport solution <br>
that offers a high degree of robustness via joint
information relaying. <o:p></o:p></span></p>
