This involves maintaining or improving its performance at a lower operational cost. This need is also aided by the fact that the industry has been experiencing declining profitability. This has resulted in the industry looking at solutions like virtualization and resource pooling or cloudification among others. Recent studies have concluded on container-based virtualization for better performance. However, there are different container providers and choosing a less performant provider increases deployment costs. Additionally, to foster sustainability and adoption of the virtualization, its management and orchestration (MANO) needs to conform to the ETSI (European Telecommunication Standards Institute) network function virtualization (NFV) MANO standards. Hence, this paper designs and implements an ETSI complaint NFV MANO for container-based virtualization using the most performant container provider, LXC. In order to cater for horizontal scaling and distributed services, we promptly incorporate multi-host, multi-cloud in the design","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129994793","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 will demonstrate that subband filtered URLLC allows to achieve highly reliable link performance, which is not affected by interference induced by a mobile broadband service using a different numerology. In addition, we analyze and demonstrate asynchronous URLLC uplink performance with relaxed power control requirements to show that significant receiving power differences in the 5G NR base station (gNB) receiver can be tolerated, especially if highly selective subband filtering is applied in both the URLLC devices transmitters and the gNB’s receiver. We also demonstrate how the mobile broadband users may be interfered by the URLLC users in mixed numerology scenario, unless sufficient guard bands and sophisticated waveform signal processing solutions improving spectral localization in transmitter and receiver side are applied. Overall, the results show that by using subband filtering on top of basic CP-OFDM processing, frequency multiplexing URLLC and enhanced mobile broadband (eMBB) services within one 5G NR carrier is feasible.","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126548423","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}

It brings computing and storage resources to the edge of the network, enabling cloud computing capabilities and an information technology service environment with low-latency communication. However, when an edge server occupies the same facility as a base station, its available computation resources may be limited for physical reasons, such as restricted space and inadequate temperature control. To provide high-load services for mobile users, reference [1] proposed an edge cloud with servers distributed in a hierarchical topology. The proposed architecture can provide high-load services by using a hierarchical collection of edge servers, but the communication delay increases when a requested service is processed by a server at a significant functional distance from the user. The increased delay affects the service quality because almost all services handled by edge servers will be delay-sensitive. To decrease the completion delay of such a task, we propose a method of workload placement that considers both computation and communication delays. The workload placement determines which edge server will process a requested task in the hierarchy architecture for a mobile user. Our method consists of a procedure to determine the workload placement and to exchange key information for that determination. In this paper, we present our proposed method and its evaluation by computer simulation.","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133869493","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 serving base stations (BSs) are mounted over unmanned aerial vehicles (UAVs), allowing for their initial placement as per the user geographic distribution. With recent air-to-ground channel modeling adopted herein, we focus on addressing the problem of coordinated channel assignment from within a reusable channel pool at each of the operator-deployed UAV-BSs along with the consideration of backhaul constraint. The joint association/channel assignment problem, which enables a flexible design of the inter-cell interference terms experienced by the users, is cast into a mixed integer linear program (MILP) that is numerically solved. Due to being a non-deterministic polynomial time (NP)-hard problem, the computation time may unboundedly grow, especially as the number of network nodes increases. To solve this problem, a low-complexity heuristic algorithm is proposed. The proposed heuristic solution is compared to that obtained via the MOSEK solver, revealing a close achievable performance with much less computational complexity.","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"300 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115240670","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}

Amidst this transition, addressing the connectivity needs of rural areas is still a distant dream. In this article, we discuss the connectivity requirements of rural areas and also present a network architecture based on these requirements. Low energy, low mobility, and large cell are the key aspects when designing a broadband network for rural areas. We refer to this network as the Frugal 5G network. We discuss two testbeds that we have deployed in India based on the Frugal 5G network architecture. The first testbed spanning 7 villages studies the feasibility of providing high-speed connectivity to rural areas via TV UHF band. The second testbed has been scaled up to 25 villages and studies the feasibility of connecting the rural areas by employing IEEE 802.11 (5.8 GHz) technology. Deploying such a large scale network requires efficient planning which is also discussed in the paper. Sustainability of the rural broadband network is an important issue and has been addressed by proposing a multi-stakeholder partnership model. Insights obtained from these testbed deployments suggest that for connectivity to be sustainable, network planning, use of renewable energy, local support & community participation, and efficient business model are the cornerstones that should be adhered to.","PeriodicalId":121352,"journal":{"name":"2019 IEEE Wireless Communications and Networking Conference Workshop (WCNCW)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126657983","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}
