Conference Paper
Full-text available
Most underwater acoustic communication systems incorporate well-recognized, easily detectable narrowband signals modulated over low-frequency carriers at high transmission powers, which ultimately limits LPD/LPI performance of the communication scheme. While there have been promising works concentrating on LPD/LPI performance, they are for the most...

Information-Centric Networks expose content information to the network layer. CCN, NDN and others want to replace IP as the narrow waist of the Internet. In iDNS, it is argued that most of the benefits of ICN can be achieved in IP through modification of DNS, and by adding a new content record (CR) type to the records returned by a DNS server. This...
