One recent solution for this is based on a two-layered network that uses long-range macro cells to provide a full coverage signaling overlay and short-range small cells for fast data transmissions. These small cells can be switched off when they are not needed and allow network-wide energy optimizations. This paper presents an architecture that extends existing mobile networks to integrate a small cell layer that supports on-demand cell activation. We discuss how additional small cells can be interconnected with existing core components and how they can be controlled by a resource management component. Finally, a Wi-Fi based proof of concept testbed implementation is presented that demonstrates the feasibility of the approach.","PeriodicalId":166050,"journal":{"name":"Proceedings of the 5th Workshop on All Things Cellular: Operations, Applications and Challenges","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130694758","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}

The key idea is to strategically leverage Server Push, a built-in feature in HTTP/2, to preemptively push web pages' metadata, which can later be leveraged by the client to early-fetch critical resources. We demonstrate MetaPush is particularly suitable for cellular networks, providing negligible bandwidth overhead (around 0.4%), improved page load time (up to 45%), and reduced radio energy utilization (up to 37%) over HSPA+ networks.","PeriodicalId":166050,"journal":{"name":"Proceedings of the 5th Workshop on All Things Cellular: Operations, Applications and Challenges","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125282015","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}

In particular, we aim to study the impact of user indoor/outdoor environment context at time of measurement. Focusing on signal strength as the measurement metric and using a real large crowdsourced measurement dataset for central London area along with estimated environment state (indoor or outdoor), we show that indoor-outdoor context has a significant impact, suggesting that conflating indoor and outdoor measurements can lead to unreliable results. We validate these observations using a set of diverse and controlled measurements with indoor/outdoor ground truth information. We also discuss some opportunities for future work (e.g., accurate and efficient context detection) relevant to crowdsourced mobile network measurement systems.","PeriodicalId":166050,"journal":{"name":"Proceedings of the 5th Workshop on All Things Cellular: Operations, Applications and Challenges","volume":"129 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127094121","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}

We formally introduce an optimization model to address this question and propose an online algorithm for dynamic caching and request assignment. Crucially our request assignment scheme is based on a server price signal that jointly reflects content and bandwidth availability. We prove that our algorithm is optimal and stable in a limiting regime that is obtained by scaling the arrival rates and content chunking. From an implementation standpoint, guided by the online algorithm we design a light-weight scheme for request assignments that is based on load and cache-miss cost signals; for cache replacements, we propose to use the popular LRU (Least Recently Used) strategy. Through simulations, we exhibit the efficacy of our joint-price based request assignment strategy in comparison to the common practices of assigning requests purely based on either bandwidth availability or content availability.","PeriodicalId":166050,"journal":{"name":"Proceedings of the 5th Workshop on All Things Cellular: Operations, Applications and Challenges","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127307436","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}

We are living in an increasingly connected mobile world, where smartphones and tablets are prevalent, the use of wearable devices is growing, and the \"Internet of Things\" is permeating our lives. An important part of this ecosystem is the underlying connectivity provided by cellular networks. While innovations in mobile services and applications have thrived, innovations in the underlying cellular systems are more limited. Specifically, research in mobile cellular networks has been hampered by the fact that academic researchers typically do not have access to radios, mobile protocol stacks, management tools, and realistic cellular network traces. The goal of this workshop is to bring together network operators, as well as researchers from both industry and academia, to discuss emerging problems, challenges, and potential solutions in this domain. \u0000 \u0000We solicited papers on these topics to kick-start discussions at the workshop. We received 16 submissions, each of which received at least three reviews from our 19 expert reviewers. With their hard work and careful evaluation, we accepted 8 exciting papers to be presented at the workshop. \u0000 \u0000The workshop program is designed to be interactive, with short talks followed by mini panel discussions with all paper presenters at the end of each session. Additionally, we are grateful to have Goran Rune from Ericsson to give a keynote address discussing challenges and opportunities in 5G cellular networks. Finally, we thank the SIGCOMM organization for hosting this workshop. We hope you enjoy the workshop, and look forward to an interesting and productive day!","PeriodicalId":166050,"journal":{"name":"Proceedings of the 5th Workshop on All Things Cellular: Operations, Applications and Challenges","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134110814","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}

We report the results of a measurement study of round trip delays in two mobile networks in Norway using over 200 geographically distributed subscriptions for a period of one month. In general, we find high variation in delay within the same radio access type and RRC state. Across both networks we study, we observe connections with round trip delays of several seconds, often multiple times per hour, that are more frequent when nodes are moving. Correlating these extreme delay events with available metadata, we find they are related to handovers, radio state transitions, and retransmissions at the link and physical layers.","PeriodicalId":166050,"journal":{"name":"Proceedings of the 5th Workshop on All Things Cellular: Operations, Applications and Challenges","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115250575","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}

In this paper, we analyze cellular network traces of different generations from three major cities in China during 2010 and 2013 and a city in Southeast Asian country in 2013. We analyze (i) cellular traffic, (ii) throughput, round-trip time (RTT), and loss rate, and (iii) how they are affected by cellular modes, time, and geographic locations. We find the TCP performance in our traces is much worse than those reported in previous 3G measurement studies from North America and Europe likely due to more expensive cellular data plan and more limited cellular resources. We further use machine learning to diagnose reasons behind high RTT and losses, and identify major factors that limit TCP throughput. Our analysis shed light on important characteristics of cellular traffic and performance in large-scale cellular networks.","PeriodicalId":166050,"journal":{"name":"Proceedings of the 5th Workshop on All Things Cellular: Operations, Applications and Challenges","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131600651","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}

In this context, understanding the Quality of Experience (QoE) of popular services in such devices becomes paramount for cellular network operators, who need to offer high quality levels to reduce the risks of customers churning for quality dissatisfaction. In this paper we study the problem of QoE provisioning in smartphones, presenting the results obtained from subjective lab tests performed for five popular apps: YouTube, Facebook, Web browsing through Chrome, Google Maps, and WhatsApp. The analysis addresses the impact of the access downlink bandwidth on the QoE of these apps when accessed through smartphones. The results presented in this paper provide a sound basis for better understanding the QoE requirements of popular services and mobile apps, as well as for dimensioning the underlying provisioning network. To the best of our knowledge, this is the first paper providing such a comprehensive analysis of QoE in mobile devices.","PeriodicalId":166050,"journal":{"name":"Proceedings of the 5th Workshop on All Things Cellular: Operations, Applications and Challenges","volume":"108 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-08-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132484685","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}
