Loss-resilient on-demand media streaming using priority encoding
A novel solution to the reliable multicast problem is the “digital fountain” approach, in which data is encoded with an erasure protection code before transmission, and receiv...

Adding Redundancy to Replication in Window-aware Delay-tolerant Routing
— This paper presents a resource-efficient protocol for opportunistic routing in delay-tolerant networks (DTN). First, our approach exploits the context of mobile nodes (speed, ...

Idle sense: an optimal access method for high throughput and fairness in rate diverse wireless LANs
We consider wireless LANs such as IEEE 802.11 operating in the unlicensed radio spectrum. While their nominal bit rates have increased considerably, the MAC layer remains practica...
