To provide full functionality, smartwatches are usually connected to phones via Bluetooth. However, the Bluetooth power characteristics and the energy impact of Bluetooth data traffic have been rarely studied. To address this issue, we first establish the Bluetooth power model based on extensive measurements and a thorough examination of the Bluetooth implementation on Android smartwatches. Then we perform the first in-depth investigation of the background data transfers on smartwatches, and find that they are prevalent and consume a large amount of energy. For example, our experiments show that the smartwatch's battery life can be reduced to one third (or even worse) due to background data transfers. Such high energy cost is caused by many unnecessary data transfers and the energy inefficiency attributed to the adverse interaction between the data transfer pattern (i.e., frequently transferring small data) and the Bluetooth energy characteristics (i.e., the tail effect). Based on the identified causes, we propose four energy optimization techniques, which are fast dormancy, phone-initiated polling, two-stage sensor processing, and context-aware pushing. The first one aims to reduce tail energy for delay-tolerant data transfers. The latter three are designed for specific applications which are responsible for most background data transfers. Evaluation results show that jointly using these techniques can save 70.6% of the Bluetooth energy.","PeriodicalId":6462,"journal":{"name":"2017 IEEE 25th International Conference on Network Protocols (ICNP)","volume":"25 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78075026","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, the reactive events raised by such flexible model meanwhile consume lots of the bottleneck resources of the fast memory in switch and bandwidth between controller and switches. To address this problem, we propose SoftRing with the motivation to mitigate the overhead to handle a reactive event. In fact, the reactive packets are not necessarily stored in the switch or sent to the controller; instead, they are forwarded to traverse a pre-defined loop path. The packets will finally leave the loop path after the switch rules related to the packet flow being updated to switches in the loop with fewer flow entries. We have implemented a SoftRing system that integrates the controller and software/hardware SDN switches. The results show that SoftRing can eliminate the fast memory requirement for reactive packets and reduce the control channel bandwidth consumption up to 80%, with the cost of less than 5% data plane bandwidth, an average of three extra flow entries in each switch, and minor extra latency for the flow forwarding.","PeriodicalId":6462,"journal":{"name":"2017 IEEE 25th International Conference on Network Protocols (ICNP)","volume":"49 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74926682","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}

This provides various benefits including bandwidth aggregation and fast handovers on mobiles. A Multipath TCP connection starts with a single TCP connection called subflow and other subflows are added later to increase bandwidth or support failover. One drawback of Multipath TCP is that it is not currently compatible with stateless load balancers which rely on the five-tuple for their forwarding decision. This hinders the deployment of Multipath TCP. We show that this limitation can be circumvented with a small change to the handling of the initial subflow. Clients use this subflow to discover the load-balanced server and the additional Multipath TCP subflows are terminated at a unique address associated to each physical server. With this small change, Multipath TCP becomes compatible with existing stateless load balancers. Furthermore, we show that the same approach enables anycast Multipath TCP services, a major benefit given the difficulty of deploying anycast TCP services. We implement this modification in the Linux kernel and demonstrate its benefits with several micro benchmarks.","PeriodicalId":6462,"journal":{"name":"2017 IEEE 25th International Conference on Network Protocols (ICNP)","volume":"18 1","pages":"1-10"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87033723","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}
