DTN (Delay/Disruption Tolerant Networking) inserts a new layer between the application layer (L7) and the transport layer (L4) for reliable communication on long-delay, intermittent, or lossy inks. Such a new layer, however, should provide not only a single rich service but also various rich services. We are proposing Layer-5 (L5) inserted between L7 and L4 to provide multiple rich services. One of...
Over the past few years, many scientists have envisioned an Internet generation that will not only provide voice and data communications but can also support Haptic communications. This new Internet dimension can be beneficial for the society by facilitating the development of new technologies and applications that will improve our standards of living. In this study, we propose a novel traffic engineering...
In challenged networks, such as opportunistic networks or Delay Tolerant Networks (DTNs), due to frequent network partition an end-to-end connection between source and destination may not always be possible due to nodes move unpredictably with high speeds. For such type of networks, traditional routing protocols fails to transmit and also no guarantee on delivery of data to specified destination because...
End-to-end communication usually adopts a single path to transmit interactive packets in traditional routing mechanisms, so attackers can easily snoop into the whole communication trace to analyze users' typical features and to predict users' next-behaviors, which can severely decrease the security of users' information. Thus, this paper puts forward a multi-path based link-state routing mechanism,...
We present the framework for a heterogeneous internetworking service architecture to provide probabilistic quality of service guarantees to short critical messages prior to transmission. The TCP/IP Internet is not suited to bear mission-critical data across administrative domain boundaries with stringent delivery requirements because Border Gateway Protocol obscures network state information. Critical...
Delay Tolerant Network (DTN) shows some features like link frequent interruptions, long delays, limited resources and so on, while nodes fight each other to win the network resources in the process of communication, which can lead to network congestion in delay tolerant network. Therefore, congestion control is a key issue in delay tolerant network research. The present congestion control strategies...
