Throughput and fairness maximization problem in a finite horizon (short term) is formulated as a novel multi-window optimization problem. Through analysis users' thresholds are shown to be time variant to achieve throughput maximization with fairness in each window. Simulation results clearly show that compared with non decision-based strategy, ratio-based scheme achieves within 1.6 % of the maximum throughput value and is scalable in terms of the number of nodes. Fairness performance is marginally better than non decision-based strategy.","PeriodicalId":232205,"journal":{"name":"2010 IEEE Globecom Workshops","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114214909","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 this paper we have developed a novel body sensor network based recognition system to identify the specific gait pattern of Parkinson's disease (PD). Firstly, a BSN with 16 nodes is used to acquire the gait information from the PD patients. Then, an algorithm is developed based on local linear embedding (LLE) to extract and recognize the gait features. Experiments demonstrate the effectiveness of proposed scheme. The results show that the proposed scheme has a recognition rate of about 95.57% for gait patterns of PD, which is higher than the conventional PCA feature extraction method. The proposed system can identify PD patients from normal people and by their gait map with high reliability and appears a promising aid in the diagnosis of the Parkinson's disease.","PeriodicalId":232205,"journal":{"name":"2010 IEEE Globecom Workshops","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121653901","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 this paper, the Box-Cox transformation has been proposed as a unified approach that would cover all the former distributions.

But there is a gap between application developer communities and the Telecom industry. The Telecom industry offers its services so developers can use them in their applications but developers don't have any incentives, tools or development environments that would help them to overcome the barriers of accessing the communication services in order to build converged distributed Internet-Telecommunication applications. This research work presents a concept for how to close this gap by evaluating the requirements of the different stakeholders and combining application store concepts (e.g. Apple AppStore, Google Market) with open telecommunication SDP architecture concepts. Outlined is a concept for Application Delivery Platforms (ADP) that extends the concept of SDPs by broadening the focus from re-usable services over application development and lifecycle management to end user applications on client platforms and devices.","PeriodicalId":232205,"journal":{"name":"2010 IEEE Globecom Workshops","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133833897","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}

Therefore, a highly accurate sensing technique to know the presence of licensed users is essential. For such a purpose, soft decision cooperative spectrum sensing techniques are proposed. In a soft decision cooperative spectrum sensing, the cognitive base station collects the received signal energy information from multiple users. Since the bandwidth of the control channel used for collecting the energy information is limited, it is necessary to quantize the received signal energy information in each user. In this paper, we propose a quantization scheme based on the probability of false alarm for the soft decision cooperative spectrum sensing. The quantization criterion is analytically derived, and the theoretical expression for the resultant probability of false alarm is presented with taking the quantization error into account.","PeriodicalId":232205,"journal":{"name":"2010 IEEE Globecom Workshops","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134251384","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}

Moreover, an efficient algorithm is developed to solve the problem for a fixed bandwidth allocation. The optimal solution assigns all available power to the users.

Flexibility and automatic reconfiguration are two significant features in Long Term Evolution (LTE) systems. The Tracking Area List (TAL) is a novel concept in LTE systems, which allows a more flexible configurations, expecting to reduce the overall signaling overhead. In this paper, we first present a ”rule of thumb” method to allocate and assign TALs for a network. The easily applied approach does not require any data other than what is available for conventional TA design. Second we compare the performance of an optimum conventional TA design with the suggested TAL design for a large scale network in Lisbon, Portugal. A thorough computation is done to make a justified evaluation. We follow the comparison during specific time intervals for one complete day, and we illustrate the performance of reconfiguration for each approach. The results clearly demonstrate the ability of dynamic TAL in reducing the signaling overhead and maintaining a good performance due to reconfiguration compared to the conventional TA design.","PeriodicalId":232205,"journal":{"name":"2010 IEEE Globecom Workshops","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131017301","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 optical Multiple-Input-Single-Output (MISO) channel used here is obtained through measurements. The experimental setup consists of two lasers and an optical receiver. Using the channel measurements, the performance of SSK is compared to the Single-Input-Single-Output (SISO) transmission case. We build upon a recent finding, obtained for a two-transmitter case, that power imbalance at the transmitters can enhance the performance of SSK, especially in highly correlated channels [1]. It is found in this paper that SSK applied to real optical wireless channels outperforms SISO and Single-Input-Multiple-Output (SIMO) transmission if more than four optical transmitters are used. Furthermore, we show that Space Shift Keying can also exceed Multiple-Input-Multiple-Output (MIMO) setups which apply repetition coding as SSK exploits receive-diversity in a better way.","PeriodicalId":232205,"journal":{"name":"2010 IEEE Globecom Workshops","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133293119","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}
