{"title":"Controlled Interference Generation for Wireless Coexistence Research","authors":"Anwar Hithnawi, Vaibhav Kulkarni, Su Li, Hossein Shafagh","doi":"10.1145/2801676.2801682","DOIUrl":"https://doi.org/10.1145/2801676.2801682","url":null,"abstract":"In recent years, we have witnessed a proliferation of wireless technologies and devices operating in the unlicensed bands. The resulting escalation of wireless demand has put enormous pressure on available spectrum. This raises a unique set of communication challenges, notably co-existence, Cross Technology Interference (CTI), and fairness amidst high uncertainty and scarcity of interference-free channels. Consequently, there is a strong need for understanding and debugging the performance of existing wireless protocols and systems under various patterns of interference. Therefore, we need to augment testbeds with tools that can enable repeatable generation of realistic interference patterns. This would primarily facilitate wireless coexistence research experimentation. The heterogeneity of the existing wireless devices and protocols operating in the unlicensed bands makes interference hard to model. Meanwhile, researchers working on wireless coexistence generally use interference generated from various radio appliances. The lack of a systematic way of controlling these appliances makes it inconvenient to run experiments, particularly in remote testbeds. In this paper, we present a Controlled Interference Generator (CIG) framework for wireless networks. In the design of CIG, we consider a unified approach that incorporates a careful selection of interferer technologies (implemented in software), to expose networks to realistic interference patterns. We validate the resemblance of interference generated by CIG and interference from represented RF devices, by showing the accuracy in temporal and spectral domains.","PeriodicalId":184216,"journal":{"name":"Proceedings of the 2015 Workshop on Software Radio Implementation Forum","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126260241","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Proceedings of the 2015 Workshop on Software Radio Implementation Forum","authors":"Li Li, T. Rondeau, Jonathan M. Smith","doi":"10.1145/2801676","DOIUrl":"https://doi.org/10.1145/2801676","url":null,"abstract":"Last year, we talked to a thirty-six year old satellite on its way back after a wild journey through the solar system. Without the original hardware around to talk to it, a group of enthusiasts put together a software defined radio solution within weeks to reopen our communications with the ICE-3/ISEE-3 satellite. Using the open source GNU Radio software and an Ettus Research software radio frontend, they plugged into the Arecibo Observatory, the world's largest singleaperture radio telescope, and began talking. \u0000 \u0000Software radio had done something we could not have done any other way given the time constraints on the window of opportunity. The team of engineers and scientists that did this showed us the power and flexibility of what we have achieved in software radio. But the promise of SDR is not just in its malleability. We are looking to the future of communications and the next great ideas. SDR blends the physics of radio, the math of signal processing, and the innovation of computer science. The merging of these domains opens up possibilities in performance and crosslayer development that will extend into new ways of thinking about communications and platforms. \u0000 \u0000The Software Radio Implementation Forum (SRIF) encompasses the academic pursuit of understanding the possibilities and limitations of software radio technology. The papers, posters, and demos shown over the past three years and those of this current year are working on new ways take advantage of software radio. In the agenda for SRIF'15, the authors will present how to enhance software radio with innovations in computer processors, explore applications spaces for what new capabilities with which we are now presented, and looking at how the spanning of computer and radio hardware and software leads to new ways of doing cross-domain work. In the latter, we see work both in cross-layer optimization as well as utilizing different levels of the computer architecture to enhance our use of memory and operating system concepts. \u0000 \u0000We are pleased to welcome everyone to the fourth SRIF workshop in Paris as a MobiCom workshop. We have presenters, posters, and demonstrations from all over the world selected by a strong and dedicated program committee.","PeriodicalId":184216,"journal":{"name":"Proceedings of the 2015 Workshop on Software Radio Implementation Forum","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129728864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
