In this paper, we draw from the motivational work of McDonald and Cranor [18] on web privacy policies to investigate the opportunity cost for users and the United States if people would read these permission screens on mobile devices during installation or launch time. We also demonstrate the time and cost differences between different versions of Android's permissions model. Based on our findings, an average user of Android M may spend less than two minutes annually viewing permission screens. This would mean a maximum annual opportunity cost of $1.29 and a minimum of $0.16 based on whether it was read at work or leisure. Reading detailed permissions screens in older versions of Android could require a user to spend nearly 90 minutes annually with a maximum cost of $67.24 and a minimum of $8.40. In our estimates, the United States would have to invest between a leisure cost of $36.67 million and a work cost of $293.6 million for Android M. However, these costs are small in comparison to costs needed in older versions of Android that could use up to as much as $1.87 billion in leisure costs and $15.03 billion in work costs. We conclude that updates to Google's permissions layout has reduced the time and opportunity cost to the point where, with Android M, they are at an all-time low.","PeriodicalId":172085,"journal":{"name":"Proceedings of the 3rd Workshop on Hot Topics in Wireless","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127397508","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}

However, Wi-Fi has long been underutilized in the IoT space in favor of other wireless protocols such as Zigbee or BLE. This results in less than optimal deployment solutions that do not fully take advantage of the enormous existing installation base of Wi-Fi. One of the main reasons for the lack of use of Wi-Fi in IoT is the incredible power consumtion of Wi-Fi radios. While transmitting, a Wi-Fi radio can consume 100s of mW of power, much too much for a simple batter limited IoT device. With Passive Wi-Fi we show how Wi-Fi connectivity can be achieved for 10,000x lower power than traditional Wi-Fi and 1,000x lower power than BLE or Zigbee by synthesizing Wi-Fi packets using only reflections. This opens up the possibility of using Wi-Fi everywhere, even on the most power constrained of IoT devices. Additionally, with Interscatter we demonstrate how to use reflections to transform BLE transmissions into Wi-Fi packets. This can allow phones, smartwatches, or other BLE devices to interrogate low power backscatter devices with no hardware modifications, and brings backscatter into the personal area network space. These technologies have the potential to make backscatter a first class citizen in IoT wireless communication by allowing them to communicate with existing ecosystems and current consumer devices.","PeriodicalId":172085,"journal":{"name":"Proceedings of the 3rd Workshop on Hot Topics in Wireless","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125656689","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}

Creating the illusion of immersion on HMDs requires high framerate, low latency, and high visual quality --- a tall order for mobile device-based VR approaches. In this talk, I will discuss two systems we have built to overcome the inherent limitations of mobile VR. The first, Outatime, focuses on compute offload via app streaming, an emerging app execution model in which remote rendering servers stream interactive video to thin clients. While servers dwarf mobile devices in compute power, the key challenge is coping with network latency. I will discuss how we have employed speculative execution to overcome this challenge on high-quality VR games. The second system, Flashback, aggressively precomputes all possible images that a VR user might encounter well ahead of time. During run-time, Flashback indexes into the device's storage hierarchy to quickly lookup images that the user ought to be seeing. Flashback not only works for static scenes, but also for dynamic scenes with moving and animated objects. We observe substantial improvements in framerate, latency and energy consumption. In some cases, it even delivers better framerate and responsiveness than a tethered high-end computer.","PeriodicalId":172085,"journal":{"name":"Proceedings of the 3rd Workshop on Hot Topics in Wireless","volume":"196 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125269323","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}
