Today, the number of concurrent packets in a MIMO LAN is limited by the number of antennas on the AP. This paper shows how to overcome this limit. It presents a new design where multiple client-AP pairs can communicate ...

The traditional contract between the network and the lower layers states that the network does routing and the lower layers deliver correct packets. In a wireless network, however, different nodes may hear most bits in a ...

The fundamental problem of wireless video multicast is to scalably serve multiple receivers which may have very different channel characteristics. Ideally, one would like to broadcast a single stream that allows each ...

Wideband technologies in the unlicensed spectrum can satisfy the ever-increasing demands for wireless bandwidth created by emerging rich media applications. The key challenge for such systems, however, is to allow narrowband ...

We demonstrate a freespace optical system using a consumer camera and projector in indoor environments using available devices for visual computing. Through design, prototype and experimentation with this commodity hardware, ...

This paper presents M&M, a passive measurement toolkitsuitable for large-scale studies of Internet path characteristics.The multiQ tool uses equally-spaced mode gaps in TCP flowsÂ’packet interarrival time distributions to ...

Recent years have witnessed many proposals for anonymous routing in overlay peer-to-peer networks. The proposed protocols either expose the receiver and the message content, or require the overlay nodes to have public-private ...

We propose a new architecture for wireless mesh networks. In addition to forwarding packets, routers mix (i.e., code) packets from different sources to increase the information content of each transmission. We show that ...

This paper proposes an isolation layer -- a shim -- betweeninter-domain routing and packet forwarding. The job of this layer isto coordinate between Autonomous Systems (AS's) on when and how tomodify the forwarding state ...

Wireless networks can suffer from high packet loss rates. This paper shows that the loss rate can be significantly reduced by exposing information readily available at the physical layer. We make the physical layer convey ...
