Byzantine fault-tolerant (BFT) replication has enjoyed a series of performance improvements, but remains costly due to its replicated work. We eliminate this cost for read-mostly ...
Broadband wireless access networks, such as the IEEE 802.16 standard for wireless metropolitan area networks (WMANs), aim to provide high bandwidth, low-cost, scalable solutions t...
Mobility is redefining the hardware and software fabric of distributed systems. Wireless communication allows network hosts to participate in a distributed computation while on t...
The main purpose of many current peer-to-peer (P2P) networks is off-line file sharing. However, a potentially very promising use of such networks is to share video streams (e.g.,...
