How to decide a scheme to share the traffic of users to different servers becomes an important indicator of the overall quality of service in this scenario. In order to reduce costs and provide high-quality and reliable service, the load balancing technology is usually used in enterprises. At present, the industry generally uses LVS and other open source software or commercial load balancing device based on traditional network to complete this feature. However, due to the high cost of existing load balancing equipment, as well as the inherent shortcomings of traditional Internet, these solutions are lack of flexibility, and user's experience is not friendly enough. This paper proposed a load balancing scheme in data center based on SDN, that can implement an efficient dynamic scheduling according to the server status, using the feature of programmability in OpenFlow network, to balance different applications and complete the rational use of data center server cluster in a scenario that user request changes drastically. We also realized an equilibrium model for different applications. In addition, this paper also uses the Mininet network simulation tool to design the experiment scene, and completes the verification of the scheme.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126287014","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}

Monitoring of multi-band wireless resources is a significant and challenging issue for multi-band WLAN. Traditional methods of sensing by access point (AP) for each basic service set (BSS) of multi-cell WLAN incurs constraints of sensing capacity as well as the spatial and spectral coverage, especially for multi-band WLAN. We consider a resource monitoring system that employs collective sensing for each BSS via multi-RF stations (STAs). Distributed and collective sensing at each BSS alleviates the constraints of AP based sensing. Meanwhile, the STA based sensing for a BSS leads to a large sensing-report overhead. In this paper, we especially address the problem of potential large spectrum consumption caused by the sensing reports from a collective of sensing entities of STAs in multi-band WLAN. We propose a distributed-and-interactive scheme to efficiently report sensing results, such as channel occupancy ratio (COR) from sensing entities. The sensing results are collected at the AP in each BSS in a WLAN. The evaluation results show that the proposed scheme leads to a very small number of reports to obtain the necessary sensing results, even for a WLAN that has a large number of sensing entities.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133516295","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 aforementioned challenge contributes to an inefficient and sluggish rescue and relief operations as miscommunication between the government, ground personnel and victims arise. Establishing a communication link in the TV White Space (TVWS) has been popular after numerous studies have shown the inefficient utilization of the TV bands. More TV spectrum was made available by the analog to digital switchover of TV broadcast which in the Philippines began in 2009. Results of the studies conducted in the Philippines showed availability of 46% to 62% TVWS in an urban area while 60% to 80% in rural area. TVWS has better propagation characteristics as compared to the ordinary Wi-Fi systems operating at 2.4 GHz and 5 GHz ISM band. In this study, the feasibility of a multi-hop network based on IEEE 802.11af standard as an alternative communication infrastructure was implemented and evaluated. Multi-hop implementation was viewed as a necessary approach to re-route the radio link around the presence of high obstruction and to increase coverage area. Adjacent, co-channel and intermodulation issue were experienced and addressed in this experiment. Results show that the deployed network attained a maximum throughput of 4.81 Mbps for uplink and 4.93 Mbps for downlink over 600 m using a single channel centered at 593 MHz. Its quality of service is seriously affected by rain with an observed drop in throughput by 17.76% although there was hardly a change in the measured RSSI. The system was able to successfully support voice and data transmission via Skype.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130729936","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}

To increase the system's communication quality, the handover scheme should be utilized when the user is moving within the limited coverage of Femtocell base stations. Generally, the Markov decision strategy is used for mobile users in the process of handover. However, the Markov decision process can't ensure the maximum utilization balance of Macrocell base stations and Femtocell base stations. In this case, users often choose the base station offering the highest signal strength, which will cause a Macrocell base station's load to be too large and Femtocell base stations to be idle, so the system's utilization is very low. To address this problem, we propose the utilization efficient game-theoretical handover scheme based on Starckberg competition theory for appropriately increasing a Femtocell base station's transmitting power. This can ensure the communication quality of the system and guarantees the system's load balance to induce users to take the initiative in processing the handover scheme. Finally, the simulation results show that our strategy is effective in choosing the best base station to receive the highest signal strength by predicting the user's movement. It could also realize the load balance of the antenna in the system. The overall transmission quality of the user group is optimized.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"190 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133216539","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 SSC-FDM arranges subcarriers non-orthogonally in the frequency domain and improves spectral efficiency by compressing the channel bandwidth compared to the conventional orthogonal frequency division multiplexing (OFDM). On the other hand, the inter-carrier inference (ICI) mainly caused by overlapped adjacent subcarriers deteriorates the communication quality. The SSC-FDM using soft canceller followed by minimum square error filter (SC-MMSE) turbo equalization has been reported to remove the ICI in the additive white Gaussian noise (AWGN) environment, while no meaningful result in the multipath fading environment has been reported at present. In addition, the SSC-FDM poses considerable difficulties in proper channel estimation and equalization in the frequency domain due to the non-orthogonal subcarrier arrangement. In this paper, we propose a receiver architecture in which time-domain equalization schemes are applied to the SSC-FDM using SC-MMSE turbo equalization, assuming the mobile communication system. In addition, the usefulness of the proposed scheme is discussed with regard to the block error rate (BLER) and throughput performance in the multipath fading environment by computer simulation.","PeriodicalId":239243,"journal":{"name":"2017 20th International Symposium on Wireless Personal Multimedia Communications (WPMC)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133302711","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}
