Malleus (zip)
Malleus changes the amplitude of your sound. You then guess what amount of attenuation was applied in dB over a range of 1 to 50 dB. Malleus can be used on an individual track or the main mix outputs. This version is the first release on CNET Download.com.

Modeling Signal Attenuation in IEEE 802.11 Wireless LANs - Vol. 1
Path loss models are used to approximate signal attenuation as a function of the distance between transmitters and receivers, being an important building block for both research and industry efforts. This paper presents experimental data that validates the use of the log-distance model both inside and outside a standard office...

Location Independent Compact Routing for Wireless Networks
While reactive routing protocols such as AODV operate efficiently for small ad hoc wireless networks, their ON per-flow control overhead limits deployment on larger-scale networks. Deployment of compact routing protocols such as geographic routing has met with challenges. This paper presents Table Attenuation Routing Protocol TARP, a protocol that combines...

On the Impact of Beamforming on Interference in Wireless Mesh Networks
For a wireless mesh network with randomly placed devices, the paper analyzes the impact of beamforming on the statistics of the signal attenuation, interference, and SIR between devices. This paper shows that simple random direction beamforming performs equally well as omni-directional transmission if no MAC layer is present. Optimized beamforming...

Troubleshooting Microsoft Windows XP-Based Wireless Networks in the Small Office or Home Office
Because small office/home office SOHO wireless networks do not have servers to perform automated configuration and verify authentication credentials, in many cases the configuration of wireless networks is done manually, which can introduce errors relating to mismatched authentication and encryption settings. Other issues such as signal interference and signal attenuation...

Link-Level Measurements From an 802.11b Mesh Network
This paper analyzes the causes of packet loss in a 38-node urban multi-hop 802.11b network. The patterns and causes of loss are important in the design of routing and error-correction protocols, as well as in network planning. The paper makes the following observations. The distribution of inter-node loss rates is...
