In light of their rapid growth, there is a pressing need to develop analysis and decision solutions whether or not. However, most of protections are limited understanding of these mobile malware and sophisticated analyzing. In this paper, we propose a method of analyzing and deciding malware on the basis of similarity with existing malware families on the popular platform, Android. We focus on the...
The software of global system for mobile channel is designed. The use of global system for mobile channel will permit to improve the accuracy of unmanned aerial vehicle location coordinates.
The development of a positioning algorithm on the board of a moving object using the information about the direction of signal reception from global system for mobile base stations. The developed system may be used as the effective and reliable method of positioning. Mobile module can help to solve all the types of positioning problems.
This paper proposes a new Wi-Fi based indoor positioning method that is robust over unstable Wi-Fi access points (APs). Because Wi-Fi based indoor positioning relies on unstable and uncontrollable infrastructure (Wi-Fi APs), the positioning performance significantly decreases when such unstable APs are included in the localization system. This paper proposes a indoor positioning method by employing...
Recent achievements of automotive telematics in the area of communication channels integration for providing a persistent bidirectional link between vehicle and cloud infrastructure have intensified research in the field of mobile multiprotocol networks of intelligent vehicles oriented on cloud and fog environmental services. Synchronization of multiprotocol unit system clock is crucial for intelligent...
Detecting plant nutrient deficiencies and evaluating fertilizer program are done by leaf tissue analysis. Unfortunately, this quantitative method is quite expensive and time consuming for traditional farmers due to its laboratory procedure. In this research, an automatic and non-destructive method based on digital image for soybean leaf color level determination was developed. Color level status is...
Noise impacts speech recognition and processing capabilities on mobile devices. The Signal-to-Noise Ratio (SNR) is a good indicator of noise in the acoustic environment where the speech is recorded and processed. In this paper, SNR and its impact on speech recognition and processing capabilities on a mobile device are studied for a relatively small text corpus of 50 words. The speech recognition accuracy...
Log-distance path loss model have been using as a simple positioning method because of its simplicity which is mainly depends on Received Signal Strength (RSS) along with path loss exponent and random Gaussian noise variable with zero-mean. This model can be extensively used in urban and remote area because it is related to energy representation. On the other hand, fingerprint positioning is also...
In China, many mobile phone users have become the victim of spam calls and suffered heavy financial loss. Discovering of call spammers can benefit mobile network operators as well as users. In this paper, we propose a time-based graph model and a simple and effective Call Log Rank(CLRank) algorithm with ranking and classification were proposed to find potential call spammers. Experimental results...
In this paper we present a simple and convenient user interface for the elderly with an open source system platform used in smartphones. This design provides a simplified interface, a large font, a big button and a simple user interface starter for easy operation, and offers the elderly a method for those who are more accustomed to dial phones. Our design includes an improved selective reply text...
With the increasing demand for video streaming in mobile environment, we have been tackling a research on throughput prediction based on the measurement history data in order to improve service quality[1][2]. Since throughput fluctuation occurs sharply in mobile environment, useless packet loss or congestion occurs when available network bandwidth is insufficient compared to the bit rate of video...
In this paper, we propose a low-cost dual-tone radio interferometric positioning system using a single mobile anchor, named mDRIPS. There is no synchronization requirement between the mobile anchor and the target. In mDRIPS, the static target continuously transmits a dual-tone signal, and the mobile anchor receives the signal at different positions along its trajectory. The instability of the target...
In this paper, we propose a stand-alone mobile visual search system based on binary features and bag of visual words framework. The contribution of this paper is two-fold: (1) a visual word-dependent substring extraction method is proposed; (2) a modified version of the local NBNN scoring method is proposed in the context of image retrieval. The proposed system improves retrieval accuracy by 11% compared...
Mobile positioning by cellular networks has received growing attention and several researches are carried out to enhance positioning algorithms and techniques that will be able to give better performance at multiple environments (outdoors/indoors). In this paper, we are interested in UTDOA (uplink time difference of arrival) approach to determine the location of a Mobile Station within an acceptable...
We are presenting a novel hybrid mobile localization system for smart mobile devices which combines the prevalence of classical wireless methods with accuracy of computer vision techniques. In the proposed framework, initial localization is roughly measured through classical wireless methods. Later computer vision techniques are deployed to refine the measurement. Specifically an image acquired by...
For the popularity of delivering video service over HTTP Adaptive Streaming (HAS) in the mobile network, developing an automatic method to evaluate customers' quality of experience (QoE) for HAS video service in real time is highly desired for network operators and content providers. This paper proposes a novel QoE evaluation strategy for HAS video service based on the specific features of HAS and...
Citizens of any country face civic problems in their day to day lives. They resort to the one of the several ways provided by the government to file their complaints. With advancements in technology, the complaint registration systems have evolved in different ways to simplify the task of registering as well as addressing the complaints. This research paper presents the architecture of a GPS based...
There is an increasing demand for indoor navigation and localization systems along with increasing popularity of location based services in last years. The paper presents our work in progress for locating indoor objects based on signal fusion. The location is based on two signals: RSSI (Received Signal Strength Indication) and video camera. This paper presents a vision-based system for human detection...
Radio Frequency IDentification (RFID) is an identification technique for storing and transferring data and it is applied for identifying and tracking tags. Our study focus on RFID tags localization by using only mobile readers without the inclusion of static readers, helps to avoid pre-deploying of static readers. We are based only on connectivity information for achieving the goal of robust 3D localization...
In this work, we address the problem of building recognition as a mobile application. Our approach exploits a small-sized vocabulary-tree of SIFT descriptors. Each SIFT descriptor in our dataset is saved along with its class label, its nearest neighbor from the vocabulary and the visual words corresponding to its spatial neighbors. To evaluate a new query image, we extract SIFT interest points and...
