Nowadays, the significance of automatic transformation of object oriented code from design models has increased due to its benefits such as cost reduction and time efficiency. Model driven development (MDD) absolutely needs automatic approach and method to generate system from model. This paper contributes the efficient Drools rule-based transformation approach to automate the mobile application development...
Mobile multimedia has today become a promising application for end users and service providers. With reference to the existing systems for mobile communications, this application further demands for solving several technical problems, especially regarding video streaming over wireless networks. An interesting approach is in form ofWireless Mesh Network (WMN) based networks, where the individual video...
Smartphone users can conveniently install a set of apps that provide Location Based Service (LBS) from markets. These LBS-based apps facilitate users in many application scenarios, but they raise concerns on the breach of privacy related to location access. Smartphone users can hardly perceive location access, especially when it happens in background. In comparison to location access in foreground,...
Web browsing is an activity that billions of mobile users perform on a daily basis. Battery life is a primary concern to many mobile users who often find their phone has died at most inconvenient times. The heterogeneous multi-core architecture is a solution for energy-efficient processing. However, the current mobile web browsers rely on the operating system to exploit the underlying hardware, which...
Today's WiFi networks deliver a large fraction of traffic. However, the performance and quality of WiFi networks are still far from satisfactory. Among many popular quality metrics (throughput, latency), the probability of successfully connecting to WiFi APs and the time cost of the WiFi connection set-up process are the two of the most critical metrics that affect WiFi users' experience. To understand...
Path metric sorting unit of successive cancellation list (SCL) decoders for polar codes is the main concern in this paper. After reviewing existing sorting units in SCL decoders, we propose 2 new sorting schemes namely quick select (QS) based selection algorithm and simplified bitonic sorter (SBT), which exploit the special data dependency of path metrics in log-likelihood ratio based SCL decoding...
Modular-based channel hopping (CH) rendezvous algorithms can provide guaranteed rendezvous for Cognitive Radio Networks (CRNs) without time synchronization or Common Control Channels (i.e., blind rendezvous). The Enhanced Jump-Stay (EJS) scheme [1] has now been recognized as arguably the best in terms of Maximum-Time-To-Rendezvous (MTTR) and bounds for the Expected-Time-To-Rendezvous (ETTR) for users...
Understanding the mobile user flow flux patterns is important for numerous applications relevant to crowd movement, from information sharing, networking, to security and public health. Particularly in instances of smart buildings and hospitals, among others, the flow between indoor locations, and mobility modeling within buildings is of a prime significance. Much of the mobility modeling studies have...
Understanding the mobile user flow flux patterns is important for numerous applications. Much of the mobility modeling studies have focused on a user-centric approach for outdoors movement. In this study, we take a location-centric approach for indoor mobility to analyze and characterize region relationships as pertains to user flow. Our study is trace-driven, as we use extensive measurements from...
The development of data services (internet) in Indonesia is increasing for each year. The research firm emarketer said that the population netter in Indonesia reached 83.7 million people in 2014, and in 2017 is estimated to reach 112 million people. pt. xyz is a company with business in telecommunications by providing data services as one of its business processes. But in that business process, often...
Caching at mobile devices, accompanied by device-to-device (D2D) communications, is one promising technique to accommodate the exponentially increasing mobile data traffic. While most previous works ignored user mobility, there are some recent works taking it into account. However, the duration of user contact times has been ignored, making it difficult to explicitly characterize the effect of mobility...
The pervasiveness of smartphones equipped with various built-in sensors combined with the capability of serving multiple applications that could access social network information introduces next generation soft biometrics tools that could be used to verify a user's identity through their social behavior. Smart mobile devices can provide multi-modal data acquisition from various social networking applications,...
Some recent research projects, inspired by the widespread availability of sensor-provided smartphones, have built harvesting experiments to collect large quantities of data in urban areas. These efforts produced new real-world datasets, typically focusing on different technological aspects (GPS and Bluetooth mobility traces or WiFi indicators) and, more recently, also on user-related data, from low-level...
This work describes a clean-slate inter-domain routing protocol designed to meet the needs of the future mobile Internet. In particular, we describe the edge-aware inter-domain routing (EIR) protocol which provides new abstractions of aggregated-nodes (aNodes) and virtual-links (vLinks) for expressing network topologies and edge network properties necessary to address next-generation mobility related...
Because of the feature of hybrid wireless mesh network, hybrid routing protocol is the most proper routing protocol for this kind of network. Hybrid routing protocol is composed of proactive routing protocol and reactive routing protocol. The proactive one is adaptive for static mesh routers, and the reactive one is suitable for mobile mesh clients. Existing hybrid routing protocols all neglect the...
The utilization of social parameters, such as the centrality principle, is vital to be considered, in order to optimally exploit the behaviour of Mobile Cloud devices. This work elaborates on the design and exploitation of social and device-centric parameters, as a typical prediction-based method in Mobile Cloud Systems with delay constraints. Based on this consideration, this work introduces a Content-oriented...
In this work, we report a study carried out to identify a set of metrics to early estimate the development effort of mobile apps. The applied methodology was inspired by the work of Mendes et al. who addressed a similar problem in the field of web apps. In particular, we extracted an initial set of metrics by analyzing the online quotes forms that companies made available on their websites. Afterward,...
The article aimed at offering new ways of routing in networks with the DTN architecture, which allows using the most optimal routes for determining the routes depending on various conditions. To achieve these goals, it is necessary to analyze the available developments in this field with the subsequent identification of advantages and disadvantages. An attempt to realize advantages with a minimum...
The origin-destination (O-D) matrix is a known indicator of individual and group mobility in transport science, an invaluable input for socio-economic activity assessment of the community, and a tool for strategic planning and policy developments. The abundance of mobility-related data allows for expansion of the ODM towards the description of the over-all socio-economic activity, of which the transport...
Holonomic systems are often complex and expensive with poor terrain handling capabilities. This paper introduces HAMR, a platform that is simple and low-cost with good terrain handling capabilities which was designed using a new method for characterizing mobility. A mobility ellipsoid (analogous to a manipulability ellipsoid) is introduced as a design tool. A metric called holonomicity measures the...
