The current Internet architecture does not properly handle multi-homed hosts, since each interface of a multi-connected end-host terminal generally appears as a completely different node. The lack of transparency about the multi-homing degree of end-hosts brings even more problems when those hosts are mobile. On the one hand, in our view the combined use of local hierarchical locators and global flat...
Cooperative relaying has been shown to provide diversity gains which can significantly improve the packet error rate (PER) in wireless transmissions. In ad hoc wireless routing where packets may travel over a number of hops before reaching the destination, hop-wise cooperative relaying may severely reduce network capacity. This approach was mainly addressed in literature so far. In this paper, we...
The ambient networks project is developing advanced networking capabilities, such as dynamic multi-access, network mobility, together with availability of ensured service or network context. The Ambient framework offers a "plug-and-play" flexibility to accommodate different routing schemes for alternative scenarios, ranging from completely flat topologies hanging off a common core network...
The mesh topology based on the standard IEEE 802.11 for wireless LANs appears to be a very promising architecture for achieving a ubiquitous wireless Internet access in the future. However, the current IEEE 802.11 protocol is aimed at single-AP (access point) environments and many problems related to the wireless meshed interconnection of APs and mobile terminals (MTs) remain to be solved. Some proposed...
