GentleRain: Cheap and Scalable Causal Consistency with Physical Clocks

Willy Zwaenepoel, Calin Iorgulescu, Jiaqing Du, Amitabha Roy

GentleRain is a new causally consistent geo-replicated data store that provides throughput comparable to eventual consistency and superior to current implementations of causal consistency. GentleRain uses a periodic aggregation protocol to deter- mine whet ...

Distributed Authentication in Anonymous Mobile Communities

Hamza Harkous

With the recent boom in smartphones technology, online social networks are going mobile. This trend urged phone manufacturers and social networking companies to seek novel business strategies to monetize from these new "gateways" and to give the users ...

Fast download but eternal seeding: The reward and punishment of Sharing Ratio Enforcement

Rameez Rahman

Many private BitTorrent communities employ Sharing Ratio Enforcement (SRE) schemes to incentivize users to contribute their upload resources. It has been demonstrated that communities that use SRE are greatly oversupplied, i.e., they have much higher seede ...

Bringing Stability to Wireless Mesh Networks

Adel Aziz

Wireless mesh networks were designed as a mean to rapidly deliver large-scale communication capabilities without the support of any prior infrastructure. Among the different properties of mesh networks, the self-organizing feature is particularly interesti ...

Fundamental limits and optimal operation in large wireless networks

Ayfer Özgür Aydin

Wireless adhoc networks consist of users that want to communicate with each other over a shared wireless medium. The users have transmitting and receiving capabilities but there is no additional infrastructure for assisting communication. This is in contra ...

Capacity enhancement in coherent optical MIMO (COMIMO) multimode fiber links

Ali H. Sayed

In this paper, we study a coherent optical MIMO (COMIEMO) multi-mode fiber link proposed for enhancing the fiber information capacity. We examine the statistical characterization of the equivalent MIMO channel and the improvement in the fiber capacity due ...

Long optically controlled delays in optical fibers

Luc Thévenaz, Kwang-Yong Song

Optically controlled delay lines in optical fibers are demonstrated by use of the group-velocity control of signal pulses based on stimulated Brillouin scattering. We achieve continuous time delay within the range of 150 ns, much larger than the width of t ...

Controlled Use of Excess Backbone Bandwidth for Providing New Services in IP-Over-WDM Networks

Patrick Thiran

We study an approach to quality-of-service (QoS) that offers end-users the choice between two service classes defined according to their level of transmission protection. The fully protected (FP) class offers end-users a guarantee of survivability in the c ...
