The model is based on a virtual network embedding (VNE) problem, i.e. the mapping of virtual networks onto a capacitated substrate network [3]. Due to parameter changes of the virtual networks (e.g. traffic demand changes) or the substrate network (e.g. network resource cost changes), embedding solutions might become sub-optimal over time. By enabling multi-step migration processes, our model takes advantage of so-called soft bottlenecks. Soft bottlenecks refer to capacity bottlenecks in the substrate network imposed by other virtual network demands which can be mitigated by releasing some of these existing demands when multiple migration steps are involved. Our model is separated into two phases. Phase I determines the optimum embedding solution, based on the current cost values, while Phase II targets the optimum migration process i.e. the transition towards the optimum embedding solution applying the concept of Time-Expanded Networks [4]. The evaluation of our model is performed using a realistic substrate network topology from SNDlib [12].","PeriodicalId":306731,"journal":{"name":"2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"11 17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116822266","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}

New applications that are expected to operate in dynamic environments must support different modes of human/machine interaction (e.g., voice and sign language), exhibit same or better performance in heterogeneous wireless and optical networks, and be able to react in real time. In particular, dispersed computing has arisen as an approach to deal with latency issues in this context. In the work described herein, we design a smart lighting IoT system that allows control of light bulbs (turn on/off, color and brightness change) through voice and sign language. This work addresses the idea of dispersed computing, which is implemented through fog computing, and combines it with virtualized resources to mitigate latency in the convergence point between wireless and optical networks. The proof-of-concept implementation of our design demonstrates the viability of the approach.","PeriodicalId":306731,"journal":{"name":"2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129574872","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}

Current offloading schemes based on offloading data to Wi-Fi regardless Wi-Fi has sufficient throughput or not. Though, we propose a novel offloading technique based on the Remaining Throughput Scheme (RTS) for Wi-Fi selection. In our proposed RTS technique, data is offloaded from the Unlicensed Long-Term Evolution (U-LTE) network such as Pico/Femto cells or Programmable Base Stations (PBSs) to Wi-Fi Access Points. Further, we propose Distance-based Transfer (DT) and Speed-based Transfer (ST) schemes to transfer users from PBS to Wi-Fi or Licensed LTE (L-LTE) Base Stations (BSs), where the transfer process relies on distance and speed of users, respectively. In this paper, the following three important issues relating to facilitating this transfer are addressed: which Wi-Fi Access Point (AP) should be selected to transfer users, which U-LTE users should be transferred to Wi-Fi, and which U-LTE users should be transferred to L-LTE. Network performance will increase by using RTS, DT and ST schemes as per the analytical evaluations presented.","PeriodicalId":306731,"journal":{"name":"2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129051022","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}

By exploiting the slow time-varying parameters and clustering UEs properly, we propose a location-assisted precoding scheme for downlink transmission. The scheme consists of two-layer precoding. The first-layer precoding is to decompose the original system into several small MIMO systems based on the location information of UEs, and is designed as a constant-envelope matrix. In this way, the number of required radio frequency (RF) chains at AP can be substantially reduced. The second-layer precoding matrix is designed to control the interference within small MIMO system. Simulation results show that the proposed scheme outperforms match filter precoding and DFT precoding in the air-to-ground transmission scenarios. Moreover, the results show that when the altitude of AP is high, increasing the number of RF chains at AP cannot improve the spectral efficiency of the system.","PeriodicalId":306731,"journal":{"name":"2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125637444","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}

As Wireless Local Area Networks (WLAN's) are not designed for such applications, assessing the communication's QoS level is a challenging task. Sudden Onset Disasters (SODs) poses even a greater challenge as the QoS level must be assessed without generating traffic or consuming any other network resources that the response forces needs for communicating among themselves. As such, passive measurement is the only viable approach, but it lacks suitable metrics for doing so. In this paper, we briefly review the main QoS parameters and later, we propose two new possible measurements. These measures are an extension of the retry-ratio measurements such as the Frame Retry Ratio (FRR) which reflects the effort-efficiency to communicate through the ratio of the extra effort (retries) to the overall effort. Data Retry-Ratio (DRR) is the ratio of extra data transmitted to the overall transmitted data in a period of time. Airtime Retry-Ratio (ARR) is the ratio of the extra airtime cost to the overall used airtime cost. For exploring the performances of these measures, we have developed and designed a special portable testbed which among other things includes a stratum-1 NTP time server. We used this testbed to explore the relations between active measurements: such as one-way delay, throughput and jitter to passive measurements: one-way throughput, one-way FRR, DDR and ARR. The results of a large field-test reveal that passive measurements can reflect the QoS parameters such as the average throughput and can indicate an asymmetric link similar to one-way delay.","PeriodicalId":306731,"journal":{"name":"2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134590961","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}

Previously, distributed SDN control methods have been discussed to improve their scalability and robustness. Distributed placement of controllers reduces computation load of each controller and backing up each other enhances robustness. However, these techniques do not include an emergency measure against large-scale failures such as network separation induced by disasters. In this paper, we design emergency reconfiguration of distributed SDN especially in control plane (C-plane). In our reactive approach, each node detects disconnection to the main controller. Then, a controller deployed on one of the disconnected nodes becomes the substitute controller to which the others reconnect. Meanwhile, C-plane should be reconstructed when network connectivity recovers in case many controllers exist. The main and substitute controllers detect networks are reconnected, and merge their C-planes to avoid conflict. Simulation results reveal that our proposed method recovers C-plane logical connectivity with probability of about 90% when regional failure occurs in 100 node networks. Furthermore, we show that convergence time of our reconstruction mechanism is proportional to network size.","PeriodicalId":306731,"journal":{"name":"2017 IEEE Conference on Computer Communications Workshops (INFOCOM WKSHPS)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131579457","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}
