I finally found the time to clean up the code for DES-Chan, the channel assignment framework, and the algorithms based on it. Work on the framework started already 4 years ago and has been grown steadily due to the great …

One of the projects during my research visit at the Monash University’s Wireless Sensor and Robot Networks Laboratory was the implementation of CSMACA for the SmartPacketRadios. The SPRs run on an Atmel AT90USB1286 microcontroller and the Hope RFM22B transceiver. It was …

As part of my PhD thesis, I investigate the impact of interference on the network performance in large-scale multi-hop wireless mesh networks. Most experiments are based on throughput measurements to determine the maximum capacity of a link in interference-prone scenarios. …

For the relaunch of reclaimyourcity.net, I recently developed a custom pager module that provides a block with links to the previous and next picture according to the particular gallery. The visibility settings for the block are restricted to the content …

Most of my work aims at reducing interference in WiFi-based multi-hop mesh networks. Since WiFi radios operate in the unlicensed frequency band, external stations and devices might be active there as well, resulting in high interference levels and eventually in a …
