- Minimizing Interference in Ad Hoc and Sensor Networks
- Reducing interference is one of the main challenges in wire-less communication, and particularly in ad hoc networks. The amount of interference experienced by a node v corresponds to the number of other nodes whose transmission range covers v. At the cost of communication links being dropped, interference can be reduced...

- Interference-Aware Channel Assignment in Multi-Radio Wireless Mesh Networks
- The capacity problem in wireless mesh networks can be alleviated by equipping the mesh routers with multiple radios tuned to non-overlapping channels. However, channel assignment presents a challenge because co-located wireless networks are likely to be tuned to the same channels. The resulting increase in interference can adversely affect performance....
