The densification of small cells on wireless networks is required to handle a lot of traffic for the cloud-based ICT services but inevitably needs a WBN to provide network connectivity at every cell. Since most traffic is delayed or dropped once a WBN suffers from a radio interference coming from outside of the WBN, it is general to avoid using the interfered channel or switch a route spatially. Although such countermeasures are effective to avoid an external radio interference, it could be less effective in terms of resource utilization because the interfered channel may still remain resource. From this perspective, we propose a method that estimates the residual resource of interfered channel and uses it as much as possible while avoiding the effect arising from the radio interference. Specifically, our proposed method uses the information about incoming/outgoing traffic to estimate the residual resource and migrate a part of traffic to another channel until the amount of incoming traffic and that of outgoing packets are balanced (i.e., the channel is not a bottleneck anymore). The experimental results showed that our method is able to estimate the residual resource of interfered channel and effectively use it even under external radio interference.","PeriodicalId":436842,"journal":{"name":"2018 IEEE 7th International Conference on Cloud Networking (CloudNet)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114969452","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}

These proposals have raised another issue that is performance fairness among TCP congestion control algorithms. Several papers were published for discussing the fairness and some of them revealed their unfairness. In addition, some fairness improving methods based on packet dropping, for example applying CoDel, have been proposed. However, these existing works were based on the existing TCP algorithms, which were loss-based, delay-based, or hybrid type TCP congestion control algorithm. In 2016, another TCP congestion control algorithm, called TCP BBR, was proposed. The algorithm is based on the congestion model by Kleinrock and not loss-based or delay-based. In this paper, we investigate the performance fairness between CUBIC TCP and TCP BBR. We present performance evaluation in conditions wherein connections of TCP BBR and CUBIC TCP are concurrently established. We then demonstrate that the performance fairness between TCP BBR and CUBIC TCP is very low, especially with high latency. In the case of 64 ms RTT, TCP BBR obtained about 45 times of performance of CUBIC TCP. We applied CoDel for improving TCP fairness and evaluated the fairness. Our evaluation showed that it did not work well in case of TCP BBR consumes much bandwidth. On the other hand, it is effective in case of TCP BBR cannot obtain enough throughput.","PeriodicalId":436842,"journal":{"name":"2018 IEEE 7th International Conference on Cloud Networking (CloudNet)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116644590","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}

One of the challenges of MEC is to reduce the cost of deploying computational resources near the cellular base stations. Recently, software implementation of cellular base stations is emerging as it allows colocation of access point functionalities and those of MEC within the same commodity hardware, e.g., using containers, thus facilitates deployment of MEC without incurring much cost. In this paper, we posit that one of the most significant challenges for realizing softwarized base stations with MEC capability is to enable resource isolation among slices, especially isolating low latency slice as the primary concern of MEC is to enable low-latency application. Our contributions are threefold. First, we define the architecture of MEC infrastructure in softwarized cellular network. Second, we measure the actual latency and throughput of on-site MEC in a softwarized cellular network. And at last, we propose a novel slicing method for softwarized base stations to isolate a low latency slice from a broadband one. Our evaluation shows that the proposed method enables reasonable resource isolation, achieving the same minimal latency even with a competing broadband slice as that without any other slice.","PeriodicalId":436842,"journal":{"name":"2018 IEEE 7th International Conference on Cloud Networking (CloudNet)","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133678062","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}

Cloud computing services have the potential to improve vehicular network services through its flexible and valuable services. These cloud network services improve the performance of the vehicular application by advance communication, traffic management, standardization and safety systems. In vehicular ad hoc networks, vehicle nodes carry more information by adopting cloud computing services and improve their sensing power, storage capabilities, and onboard computing services. Vehicular cloud computing is one of the emerging solutions to address the vehicular networks communication barriers with new hybrid technologies and remarkable storage features for traffic management and road safety by instantly using vehicular resources. In this paper, we proposed a vehicular cloud computing model for vehicular ad hoc networks. This model provides computational services to vehicle nodes and improves the data communication and network performance. In addition, the paper also discusses the proposed model different services including data aggregation, security, privacy, and resource management.
