Networked devices are often equipped with multiple interfaces. Legacy routing and transport protocols only support the transport of data over a single interface resp. paths. This tutorial discusses extensions for IP and TCP in order to support multiple interfaces. Multihoming and mobility management allow the simultaneous usage of interfaces by independent application data flows, while multipath transport...
AODV uses the minimum hop count as the connection metric do decide which route out of a set of possible routes should be selected to send a packet from a source to a destination. This metric can however be misleading if a route with a small number of hop counts is congested and interfered by neighbouring stations so that in this case another route could be faster despite of a higher hop count which...
Mobile ad hoc networks usually consist of mobile battery operated computing devices that communicate over the wireless medium and they have limited battery capacity. Many proposed routing protocols for mobile ad hoc networks concentrate on issues like the packet delivery ratio, routing overhead and shortest path between source and destination. In fact, power constraints represent an equally important...
Mobile ad hoc wireless networks (MANETs) are autonomous collections of mobile nodes that communicate over wireless links. Formal verification of routing protocols for MANETs requires concise yet property-preserving modeling to correctly verify the model and at the same time also avoid running into the problem of state-space explosion. The characteristics of MANETs that pose challenge to the task of...
A core area of P2P systems research is the topology of the overlay network. It has ranged from random unstructured networks like Gnutella to Super-Peer architectures to the recent trend of structured overlays based on distributed hash tables (DHTs) (I. Stoica et al., 2001), (A. Rowstron et al., 2001), (S. Ratnasamy et al., 2001). While the unstructured networks have excessive lookup costs and un-guaranteed...
