On Degrees of Freedom of Layered Two Unicast Networks with Delayed CSIT
In this paper we study the two unicast information flow problem over layered Gaussian networks with arbitrary number of nodes and connectivity, under the model of delayed channel state information (CSI) at transmitters and instantaneous CSI at receivers. W ...
Ieee2012Chasing the Weakest System Model for Implementing Omega and Consensus
Aguilera et al. and Malkhi et al. presented two system models, which are weaker than all previously proposed models where the eventual leader election oracle Omega can be implemented, and thus, consensus can also be solved. The former model assumes unicast ...
2009MAC layer functions for SLEF
Alaeddine El Fawal, Lorenzo Keller
We develop three functions around the MAC layer: (1) Pseudo broadcast is a technique used to improve throughput of broadcast transmissions in case of congested networks. The mechanism consists in sending a packet in unicast to a station using RTS/CTS. Othe ...
2006NASCENT: Network Layer Service for Vicinity Ad-hoc Groups
Many envisioned applications of ad hoc networks involve only small scale networks that we term Vicinity Ad-hoc Groups (VAGs). Distributed coordination services, instead of pairwise communications, are primary requirements of VAGs. Existing designs for dist ...
2004Link Weighting: An Important Basis for Charging in the Internet
Current charging mechanisms in the Internet are restricted mainly to volume and time of the day. We propose a mechanism which allows to use additional information for charging in the edges and core of the network. Links or network clouds will have weights ...
