Heterogeneous Wireless Mesh Networks (HetMesh) is a promising high throughput technology for multi-hop data forwarding by mobile clients and backbone routers in a dynamic environment. HetMesh supports Wifi-Direct facility and other separate access technologies in its mobile clients, which makes the selection of a suitable next hop forwarder for data transmission challenging. This paper proposes a...
Abstract-An overwhelming majority of existing work on soft-decision cooperative spectrum sensing makes the assumption that secondary users (SUs) in cognitive radio networks (CRNs) are stationary. Considering that mobility is an essential property of wireless networks, we analyze the detection performance of soft-decision sensing by mobile SUs. Then, a data fusion rule is proposed aiming at mobile...
Falls among elderly persons are both common and have significant negative impacts on their immediate and long-term health. In this paper, we consider whether current mobile manipulators could reduce the severity of injuries caused by human falls, and we focus on developing simple strategies toward this purpose. We present a simulation of a fall scenario that includes a humanoid and a mobile manipulator...
Mobile apps are becoming complex software systems that must be developed quickly and evolve continuously to fit new user requirements and execution contexts. However, addressing these requirements may result in poor design choices, also known as antipatterns, which may incidentally degrade software quality and performance. Thus, the automatic detection and tracking of antipatterns in this apps are...
In this paper, we propose a method to predict nextone-day-purchase behavior of "Online to Offline"(O2O) itemsbased on huge scale of user behavior log. The overall solution isdescribed in 2 parts: the feature engineering of the user behaviorlog and the ensemble of different supervised learning models. Inthe feature engineering section, besides the basic features, wefurther analyze the behavior...
Mobile adhoc networking is considered as one of the key technologies to support communication when different emergencies or disasters strike. Unfortunately, the majority of existing adhoc networking solutions are based on proprietary hardware and software which severely limits their use by only those competent authorities that are well trained and properly equipped. As a consequence, patients/victims...
With the increasing number of wireless mobile devices, the possibility of mobile communications without network infrastructure is becoming a reality. The decentralized mobile social network (MSN) is a paradigm where nodes can move freely and organize themselves arbitrarily. Therefore, the key challenge is to find routes that can provide satisfactory delivery performance and low average end-to-end...
With the popularity of the HTTP video streaming in mobile networks, the network operators are increasingly interested in the performance of the video streaming at the client-side. However, unlike content providers, network operators are not privy to the client-side or server-side, thus they have no good access to estimating the performance from the video state at the client-side. To address this limitation,...
Previously dominating research on the Internet Quality of Service (QoS), focused on network performance, has now been shifted towards the customer experience. This paper addresses Quality of Experience (QoE) management issues in the future Internet. We provide a brief overview of QoE metrics and assessment methodologies, and discuss potential relationships between the QoE and network performance parameters...
Wireless Emergency Alerts (WEA) is a public safety system that uses broadcast from cell towers to send geographically-targeted alerts and warnings to cell phones. It is one of the dissemination channels for the Integrated Public Alert and Warnings System (IPAWS). WEA typically broadcasts an alert in the cells with at least some portion affected by the emergency event. When the affected area includes...
The dynamic environment of hybrid mobile and fixed wireless networks used in military operations poses significant challenges in the efficient provisioning of software functionality to application clients. With their transient topology, the software services hosted on mobile nodes may become temporarily unavailable or the cost of transferring data across the network may become too high. To address...
This paper proposes metrics based on QoS preferences of MNs, and QoS abilities of MAPs, in order to perform a simulative evaluation of the Hierarchical Mobile IPv6 (HMIPv6) network implementation with QoS-aware dynamic MAP selection. The chosen metric meets the desired level of QoS, while retaining MAP load balance, while the DiffServ mechanism ensured the required QoS for HMIPv6 network implementation...
In MANETs, link failures are caused frequently due to node's mobility and use of unreliable wireless channels for data transmission. Multipath routing strategy can cope with the problem of the traffic overloads while balancing the network resource consumption. This article proposes an improved approach named DNDR (Dual Node-Disjoint Paths Routing) to enhance the network reliability and robustness...
Mobile learning is a rapidly growing method of learning that utilizes smart mobile devices to deliver content. A suggested M-learning framework for smart mobile applications introduced taking into consideration the following metrics (Quality of education support access to Information, Learning Modules, Collaboration, Assessments, Innovative Approaches, User-Generated Content & finally E-books,...
With more companies investing in analytics to obtain a competitive edge in the market, decision makers require better identification of valuable metrics from among their data and to be able to interpret those complex patterns more easily. The area of data mining has been heavily invested in by the research community; however there remains a gap between the visualization efforts of this newly mined...
The tremendous rate of growth in the mobile app market over the past few years has attracted many developers to build mobile apps. However, while there is no shortage of stories of how lone developers have made great fortunes from their apps, the majority of developers are struggling to break even. For those struggling developers, knowing the “DNA” (i.e., characteristics) of high-rated apps is the...
The growth of the mobile phone users has led to a dramatic increase in SMS spam messages. Though in most parts of the world, mobile messaging channel is currently regarded as “clean” and trusted, on the contrast recent reports clearly indicate that the volume of mobile phone spam is dramatically increasing year by year. It is an evolving setback especially in the Middle East and Asia. SMS spam filtering...
Mobile WiFi devices are becoming increasingly popular in non-seamless and user-controlled mobile traffic offloading alongside the standard WiFi hotspots. Unlike the operator-controlled hotspots, a mobile WiFi device relies on the capacity of the macro-cell for the data rate allocated to it. This type of devices can help offloading data traffic from the macro-cell base station and serve the end users...
The use of mobile communication applications, services, and technologies has become an indispensable part of everyday life, a fact which has promoted research on the assessment of human exposure to radio-frequency electromagnetic fields and related health issues. To evaluate personal exposure to wireless technologies and broadcast transmitters in this study the personal exposure meters with triaxial...
GeoSocial Networks (GSNs) are becoming increasingly popular due to its power in providing high-performance and flexible service capabilities. More and more internet users have accepted this innovative service model. However, although GSNs have great business value for data analysis by integrated with location information, it may seriously compromise users' privacy in publishing the GSN data. In this...
