However, the SMS is not natively designed to exchange medium/large-sized amount of data and it has been shown that such facility is highly unreliable, especially when some particular conditions occur. In this work, we propose an efficient protocol which allows to emulate a reliable data channel on data less devices, by using the SMS as underlying communication facility. Such protocol overcomes the issues arising from the structure and the functioning of that facility, when it has to send/receive significant amount of data. The approach we propose enables to transfer a variable-sized amount of data through SMS messages, with the main aim of ensuring the reliability of communication as well as of minimizing other factors, such as the number of SMS messages sent and the energy required to perform such tasks. These characteristics make the protocol we propose suitable for data communication when the only network coverage available is the Global System for Mobile Communications (GSM) and consequently, the SMS is the only facility to exploit. In addition, we address both the constraints arising from the limited energy budget of mobile devices and the security issues emerging in this context.","PeriodicalId":345694,"journal":{"name":"2014 Eighth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128199190","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}

There are two functions in this mechanism. First, secondary user (SU) transmitter sends the RTS frame including transmission power to SU receiver, SU receiver sends CTS frame including receiving power to SU sender. Monitor nodes send position and receiving power to SU sender and SU receiver. SU transmitter selects three monitors that their receiving powers are approach to each other. SU transmitter estimates its position and sending power by deterministic propagation model. This will reduce the interference to hidden PU terminal. Second, the SU in the transmission range of the PU will send one highest priority interrupt frame in control channel to one-hop SU neighbors to protect the PU. We also compare our proposed scheme to the existing IEEE 802.11 DCF and the other MAC protocols in Cognitive Radio ad hoc networks using ns2 simulation tool. We will show that CPC-MAC will improve the system throughput and reduce the energy consumption.","PeriodicalId":345694,"journal":{"name":"2014 Eighth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"11 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129218375","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}

Before a product releases, the most effective algorithm combination should be chosen to minimize the object file size or to maximize the running speed. Compilers like GCC usually have hundreds of optimization algorithms, in which they have complex relationships. Different combinations of algorithms will lead to object files with different performance. Usually developers select the combination manually, but it's unpractical since a combination for one project can't be reused for another one. In order to conquer this difficulty some approaches like iterative search, heuristic search and machine learning based optimization have been proposed. However these methods still need improvements at different aspects like speed and precision. This paper researches machine learning based compilation optimization especially on feature processing which is important for machine learning methods. Program features can be divided into static features and dynamic features. Apart from user defined static features, we design a method to generate lots of static features by template and select best ones from them. Furthermore, we observe that feature value changes during different optimization phases and implement a feature extractor to extract feature values at specific phases and predict optimization plan dynamically. Finally, we implement the prototype on GCC version 4.6 with GCC plug in system and evaluate it with benchmarks. The results show that our system has a 5% average speed up for object file running speed than GCC O3 optimization level.","PeriodicalId":345694,"journal":{"name":"2014 Eighth International Conference on Innovative Mobile and Internet Services in Ubiquitous Computing","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129715033","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}
