In this paper, we incorporate three-dimensional (3D) beamforming techniques to enable 3D spatial multiplexing of millimeter-wave communications in large cubicle office environments where there exists serious signal blockage problem. With 3D beamforming, a wireless link can be established by reflecting a focused beam off a metal-coated ceiling towards the receiver. By modeling the antenna beam with a rectangle-cone-shaped radiation pattern, we derive the “effective coverage district” of both the transmitter and the receiver to calculate interferences between different flows when they operate concurrently. We propose a heuristical concurrent transmission scheduling scheme to exploit the 3D spatial multiplexing for achieving high network throughput while maintaining good fairness among different network nodes. Extensive simulations are conducted under different network density conditions and with different background noise levels to demonstrate the effectiveness and efficiency of the proposed scheduling scheduling scheme for the 3D beamforming 60 GHz network.","PeriodicalId":174992,"journal":{"name":"2013 IEEE Globecom Workshops (GC Wkshps)","volume":"17 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120920341","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}

In order to reduce such casualties, collisions warning systems has been studied extensively. These systems are built by taking the driver reaction times into account. However, most of the existing literature focuses on characterizing how driver reaction times vary across an entire population. Therefore, many of the warnings that are given turn out to be false alarms. A false alarm occurs whenever a warning is sent, but it is not needed. This would nagate any safety benefit of the system, and could even reduce the overall safety if warnings become a distraction. In this paper, we propose our solution to address the described problem; First, we briefly describe our method for estimating the distribution of brake response times for a particular driver using data from a Vehicular Ad-Hoc Network (VANET) system. Then, we investigate how brake response times of individual drivers can be used in collision warning algorithms to reduce false alarm rates while still maintaining a high level of safety. This will yield a system that is overall more reliable and trustworthy for drivers, which could lead to wider adoption and applicability for V2V/V2I communication systems. Moreover, we show how false alarm rate varies with respect to probability of accident. Our simulation results show that by individualizing collision warnings the number of false alarms can be reduced more than 50%. Then, we conclude safety applications could potentially take full advantage of being customized to an individual's characteristics.","PeriodicalId":174992,"journal":{"name":"2013 IEEE Globecom Workshops (GC Wkshps)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122670810","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 impact is dependent on the level of burstiness of the multimedia traffic. This paper proposes eMTCP-BT, a novel energy-efficiency-oriented offloading scheme for multipath TCP (MPTCP) deliveries which considers traffic burstiness level in its decision making process. Mobile applications traffic is categorized according to its burstiness level, including some most widely-used services such as Voice over IP (VoIP) service, video streaming, large file downloading and web browsing. eMTCP-BT increases the energy efficiency of the multipath TCP content deliveries by performing an innovative distribution of the overall traffic for its delivery via the available wireless network interfaces (and paths) based on the traffic burstiness level. Real traffic trace-based simulation experiments have been conducted involving a mobile device receiving traffic over the Long Term Evolution (LTE) and IEEE 802.11 interfaces. Result analysis demonstrates how eMTCP-BT outperforms both eMTCP and the original MPTCP in terms of energy efficiency by up to 91.68%.","PeriodicalId":174992,"journal":{"name":"2013 IEEE Globecom Workshops (GC Wkshps)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122720255","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}

In specific, to calculate the energy consumption rate, one node's sampling rate is coupled with some other nodes. Moreover, because the energy consumption rate is constrained by the energy harvesting rate and current battery level to avoid depletion or overcharge of the battery, it is also coupled across the time horizon. In this paper, we will globally optimize the network utility. By dual decomposition, we decouple it into separable subproblems, which can be distributively solved without the need to coordinate with other nodes or time horizon. We then propose a distributed algorithm in the context of joint rate and battery control, which converges to the globally optimal solution. Numerical results, based on the real solar data, demonstrate that the proposed algorithm always achieves higher network utility than existing approaches.","PeriodicalId":174992,"journal":{"name":"2013 IEEE Globecom Workshops (GC Wkshps)","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127569118","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}
