In order to realize distributed applications, a group of n processes are required to cooperate with each other. In a distributed group, each member process is peer and directly exchanges messages with other processes with no centralized coordination. That is, each process sends messages to other processes and receives messages from other processes in a group. Each process has to not only reliably and efficiently but also causally deliver messages. In addition, a group is required to be scalable. In this paper, we discuss a hybrid type of clock (HC) to causally deliver messages in a scalable group. The HC protocol takes advantage of linear clock (LC) and physical clock (PC). There might be no causally precedent relation between some pair of messages ordered in the LC protocol. This means, some pair of messages are unnecessarily ordered. A physical clock in a computer is now synchronized with a time server in NTP and PTP. Thus, a process can read more precise physical time on each computer. In the LC and PC protocols, each message carries just LC and PC variables, respectively. Hence, the message length is O(1) for number n of processes in a group. We show unnecessarily ordered messages can be reduced in the HC protocol compared with the LC protocol through the evaluation of the implemented HC protocol.","PeriodicalId":227978,"journal":{"name":"2013 Eighth International Conference on Broadband and Wireless Computing, Communication and Applications","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124082865","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}

However, the pretty low resolution of the optical sensors does not allow the device to detect gestures of body parts, such as the fingers of a hand, with the same straightforwardness. Given the clear application of this technology to the field of the user interaction within immersive multimedia environments, there is the actual need to have a reliable and effective method to detect the pose of some body parts. In this paper we propose a method based on a neural network to detect in real time the hand pose, to recognize whether it is closed or not. The neural network is used to process information of color, depth and skeleton coming from the Kinect device. This information is preprocessed to extract some significant feature. The output of the neural network is then filtered with a time average, to reduce the noise due to the fluctuation of the input data. We analyze and discuss three possible implementations of the proposed method, obtaining an accuracy of 90% under good conditions of lighting and background, and even reaching the 95% in best cases, in real time.","PeriodicalId":227978,"journal":{"name":"2013 Eighth International Conference on Broadband and Wireless Computing, Communication and Applications","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124243794","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}

Besides the advantages like re-configurability and flexibility, a SDR system has to face a critical challenge on real-time processing due to high jitter and latency. Thus, understanding latency in SDR systems is very important. This paper focuses on investigating the latency of a popular SDR platform - GNU Software Radio with a new Universal Software Radio Peripherals (USRP) device -USRP Embedded Series E100. This research investigates and analyzes the reasons of the delays by considering all the buffering mechanisms in the platform. After that, we verify and quantify them by using three experimental methods. The first method is to calculate the whole delay of the SDR system by measuring the round-trip time (RTT). The second method measures subparts of the whole latency by using timestamp during a packet transmission process. The third approach is designated to measure the latency of the hardware part and bus communication part. We believe this study offers the better understanding of the latency in a new embedded USRP series - USRP E100 with GNU Software Radio platform.","PeriodicalId":227978,"journal":{"name":"2013 Eighth International Conference on Broadband and Wireless Computing, Communication and Applications","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133445011","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 such system, it is important how to locate receivers in order to construct a high performance of surveillance system. Consequently, field estimation is required to optimally allocate receivers. However, since current numerical techniques such as Ray Tracing Method (RTM) consume much computation time in order to search rays from source to receiver, they are applied to only small area within a few square kilometers. Its analytical areas are enough to investigations for cellular phone or digital broadcasting, but it is too small to obtain the field distribution in the wide area for the Air Traffic Management (ATM) system. Therefore, in this paper, we propose a new numerical algorithm for analyzing scattered fields from an aircraft in super wide area in order to apply to the development of the ATM system. The essence of the proposed algorithm based on the RTM is to simplify the ray searching from source to receiver, resulting in reducing of the computation time. We discuss the principle of our method and the theory of electromagnetic field, and we show scattered powers and delay profiles from a simple aircraft model.","PeriodicalId":227978,"journal":{"name":"2013 Eighth International Conference on Broadband and Wireless Computing, Communication and Applications","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126486136","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}
