Recent advancements in sensor, mobile computing, and wireless communication technologies have created an opportunity for mobile computing and online traffic simulations. This paper presents a distributed traffic simulation framework where traffic simulation and data processing are performed in a distributed fashion by mobile computing. In this framework, communication middleware and traffic simulation...
This paper presents a mobile computing traffic simulation based on an ad hoc distributed simulation with optimistic execution. In this system, data collection, processing, and simulations are performed in a distributed fashion. Each individual simulator models the current traffic conditions of its local vicinity focusing only on its area of interest, without modeling other less relevant areas. Collectively,...
In recent years, evaluating the influence of nodes and finding top-k influential nodes in social networks, has drawn a wide attention and has become a hot-pot research issue. Considering the characteristics of social networks, we present a novel mechanism to mine the top-k influential nodes in mobile social networks. The proposed mechanism is based on the behaviors analysis of SMS/MMS (simple messaging...
Vehicular networks can generate a large amount of vehicular data which are useful to both car consumers and manufacturers. In this paper we propose to collect vehicular data and to mine vehicular data by using data mining models. The experiment results shows the proposed methods are effective.
In this paper a novel fuzzy non-dominance routing and path ordering algorithm is presented for quality-of-service (QoS) routing for networks with inaccurate information. As one of the essential characteristic of both mobile wireless and fixed networks, the information available for decision making of QoS routing is always inaccurate[1][2]. Typically the link state information is collected by a decision...
With the rapid rising of the number of cellular phone users, accessing the Internet via mobile device is becoming a new norm in terms of network activities and people's daily life, resulting in an ever-increasing usage of the mobile Internet. This paper analyze Service Provider (SP) traffic characteristics Based on the massive data collected from a commercial Internet Service Provider (ISP) covering...
Opportunistic computing is a new computational paradigm enabling mobile users to access the heterogeneous services present in a pervasive mobile environment. With respect to conventional service-oriented approaches, in opportunistic computing services are provided by the users' mobile devices themselves, and are accessed exploiting opportunistically direct contacts between devices, i.e. without relying...
The ever-increasing number of customers and the need for higher data rates and multimedia services require the deployment of Small Cell Networks. In this paper, we propose a new computational approach to study performance and reliability of Small Cell Networks, taking into account the retrial phenomenon, the finite number of customers (mobiles) served in a cell and the random breakdowns of the base...
The purpose of the following report is to introduce a model that makes it possible to efficiently search data by using keyword-based concept network for reliable access of information which is rapidly increasing in the mobile cloud. A keyword-based concept network is a method with the application of ontology. However, the proposed model is added by association information between keyword concepts...
Energy consumption in mobile network might be excessive for some nodes acting as relays in OLSR network than others. This might have a considerable consequence on the network lifetime. Our approach is presented in the EDCR protocol. It is an extended version of OLSR which aims to increase the residual energy of the network by distributing forwarding tasks between MPRs. For that, we change the MPR...
Model coupling has been of interest due to its promise of assisting massive amounts of reuse and thereby speeding up development cycles. A project at the University of Nevada, Reno dubbed the Nevada Climate Change Portal is currently being developed to assist in providing climate data and data services to researchers. One part of this portal is being developed to enable users to define scientific...
With rapid growth of mobile devices and the emergency of mobile cloud services, it is a trend to use mobile devices for mobile-centric applications, and expand the mobile capabilities and provide needed security by mobile cloud services. However, due to the mobility of the device and the semitrust of the mobile cloud, how to build trust in the mobile applications is a big concern. In this paper, we...
Recent threats caused by worms on mobile phones are recognized as one of the most serious security threats to heterogeneous networks. Some early work model assumes that worm propagation on mobile phone cannot infect Computer in the Internet, or vice versa. However, as the development of mobile phone and multiply approaches surfing online, such as 3G, Wi-Fi, itputs hybrid nodes (mobile phone and Computer)...
In this paper, we propose a global model for WiMAX networks planning. This model consists in solving, in one shot, the network planning problem without dividing it in several subproblems. The objective of the model is to minimize the cost of the network while maximizing its survivability. The results show that the proposed model performs up to 40% better than the sequential one, which consists on...
Mobility and the absence of any fixed infrastructure make wireless Mobile Ad-hoc Networks (MANETs) very attractive for time-critical applications. In this paper, we deal with TCP congestion control for Multiple traffic in MANETs. For network simulations, we used ns-3 network simulator considering Ad hoc On-Demand Distance Vector (AODV) and Optimized Link State Routing (OLSR) routing protocols. We...
Wireless networks are continuing to attract attention for their potential use in several fields such as ad-hoc networks, sensor networks, mesh networks, and vehicular networks. Vehicular Ad-hoc networks (VANETs) are expected to be massively deployed in upcoming vehicles, because their use can improve the road safety and comfort. The effective implementation of vehicular communication could improve...
Mobility models play an influential role in the simulation studies of mobile ad hoc networks (MANETs). Realism and simplicity are two attractive properties of mobility models, and achieving both together in modeling mobility has been a challenging task. Recently, a framework of moblity models called destination guided mobility (DGM) models for MANETs was proposed. This framework can be used to develop...
In service-driven mobile ad-hoc wireless networks (MANET), it is possible that due to mobility, the service requester (client) and the service provider are no longer in the same network when the service computation is completed, while they continue to be members of other mobile networks. Once the service is invoked and the computation is started, it is important to be able to eventually deliver the...
Effectively managing the data generated by community-driven mobile geo-sensor networks is a new and challenging problem. One important step for managing and querying sensor network data is to create abstractions of the data in the form of models. These models can then be stored, retrieved, and queried, as required. There has been significant amount of prior literature on using models for query processing...
