Our paper mSync: Physical Layer Frame Synchronization Without Preamble Symbols was just accepted for publication in the IEEE Transactions on Mobile Computing.
In the paper, we propose a frame format and a corresponding decoding strategy that does not rely on dedicated preamble symbols. To evaluate our approach, we implement the algorithm for a custom low-power PHY, but also for the IEEE 802.15.4 O-QPSK PHY.
The recent project report describes how our IEEE 802.15.4 transceiver can be used for Experimental Wireless Networking Research using Software-Defined Radios.
One core assumption of many network simulators is that interference and noise have a similar impact on the performance of the physical layer. We were curious if this is actually the case and conducted simulations as well as experiments in an SDR-based testbed. The results will be published at IEEE VNC 2017 in Torino, Italy.
Researchers from the University of Minnesota used our WiFi and ZigBee transceiver to prototype their novel approach for physical-layer cross-technology communication. Their paper won the best paper award at ACM MobiCom 2017. Congratulations!
We used our WiFi transceiver implementation to study the impact of noise and interference on IEEE 802.11p. Whether there is a significant difference between noise and interference is very relevant for networks simulations, which often use very simplistic simulation models for the physical layer.
We are very happy that our paper summarizing the implementation and validation of our WiFi transceiver was accepted for publication in IEEE Transactions on Mobile Computing.
On 29 September 2017, Bastian Bloessl will participate in Probe: Research uncovered at Trinity College Dublin. He will be around at Café Curie where Marie Curie Fellows have the chance to chat about their work and give short talks.
Researchers from Spain used our WiFi transceiver for Chaos-Based Coded Modulations. Hopefully, the transceiver did not contribute to the chaos :-)
Researchers from Erlangen-Nürnberg and Mannheim use our IEEE 802.15.4 (ZigBee) transceiver in their paper on the (in)security of ZigBee 3.0 touchlink commissioning. The paper is available online.
Bastian Bloessl received a Marie Skłodowska-Curie Fellowship, allowing him to spent two more years continuing the works in the context of the Wime project. During his fellowship, he will stay at the CONNECT Centre, Trinity College Dublin – Ireland’s Research Centre for Future Networks and Communications.
Researchers from Uruguay did some really nice work on our WiFi transceiver. In their paper, published at the 9th Latin America Networking Conference (LANC’16), they present performance optimizations through more efficient demapping of constellation points and an alternate implementation of the viterbi decoder.
We are grateful that the authors contributed their modifications. They are already part of the current version.
Researchers from Technische Universität Berlin just released a paper, in which they use our WiFi transceiver to prototype their vision of a software-defined wireless network.
Jonathan Bucker shows in his blog post how to detect MAC address spoofing by associating a device with a characteristic carrier frequency offset. He uses our WiFi transceiver together with RFtap to make the frequency offset estimate available in Wireshark.

We're very happy to launch our new website, which will serve as the main source of information for everything related to the Wime project. We will use it as an outlet for theses, projects, and papers that use our tools.
If you have anything that should be added, please drop us an email. We will be happy to update the website.
A group from University of Washington used our IEEE 802.11a/g/ transceiver and our findings regarding the scrambler seeds of WiFi cards to show the feasibility of inter-technology backscatter communication. The paper will be presented at ACM SIGCOMM 2016.
