Cloud computing and Vehicular Communications are profoundly emerging fields towards realization of smart cities. While cloud computing is stage of development, vehicular cloud computing combines the benefits of Mobile Cloud Computing (MCC) and vehicular communications. Recent studies expect that vehicular cloud computing will be the gateway to the future of transportation systems. However, the development...
Mobile self-organizing ad hoc networks (MANETs) can significantly enhance the capability to coordinate the emergency actions as well as monitor contaminated areas, explore unmanned space, inspect and control working environments. The management of networks that can dynamically and freely organize into temporary topologies raises interesting problems, that are particularly challenging for networks...
Barrier coverage is attractive for many practical applications of wireless sensor networks. In stationary networks, if the number of deployed sensors is not large enough, the intruder may pass though the barrier gaps undetected. Recently, using mobile sensors to repair gaps and improve network barrier coverage performance has attracted much attention. We focus on constructing energy efficient strong...
A mobile Adhoc Network (MANET) is a huddle of autonomous mobile nodes which dynamically forms a temporary multi-hoped radio network, without any use of previous infrastructure. Due to its characteristics like limited resources, changing topology and lack of centralized administration, MANET is exposed to various network layer attacks.
Many of the models used to analyze the performance of wireless networks assume stationary traffic behaviors where the average state-changing event times are constant. Various analysis of real traffic traces have shown that such behaviors in mobile wireless networks vary periodically during the day and night. Other systems also exhibit a similar behavior. A better analysis of the network's performance...
In recent years an emerging interest in cognitive networks has been identified, since it allows the use of licensed bandwidth by ordinary users. This functionality is embedded naturally in mobile ad-hoc networks (MANET), therefore research into cognitive MANET is attractive. There are several popular tools used for research in the field of MANET, one of them is the NS-3 discrete-time simulator. However,...
A substitution network is a temporary network that self-deploys to dynamically replace a portion of a damaged infrastructure by means of a fleet of mobile routers. Some efficient solutions deploy robots based on active measurements. A robot/node in the network may use active link monitoring to assess the link quality towards its neighbors through the use of probe packets. Such probe packets are sent...
Today mobile ad-hoc network is become more popular and demanding in various applications such as emergency search operation, batter field areas etc. The reason is its economic configuration cost and infrastructure less characteristics. Additionally mobile ad-hoc network also has dynamic topology in which devices move frequently. Due to dynamic connectivity of nodes, routing operation require more...
With the rapid growth in mobile and wireless computing technology, location management techniques become a paramount issue to enable the terminals to continuously receive services when moving from one location to another. Future Personal Communication Systems (PCS) will support a huge user's population and a network spanning over a large geographical area. In such systems, the signalling traffic and...
The main objective of deploying large scale Mobile Cloud Computing (MCC) systems using the cloudlet based infrastructure is to reduce the total power consumption and the network delay while satisfying the Service Level Agreement (SLA). However, this objective is challenging to achieve due to the limited capabilities of the cloudlet system which limit the number of available services on each cloudlet...
Over the past years, different approaches have been proposed for circuital modeling photovoltaic modules. Most of these approaches introduce simplifications and/or approximations techniques or exploit inaccurate data interpolated from the plots representing panel characteristic curves: this in order to overcome the treatment of transcendental equations or to add points for numerical fitting. Unfortunately,...
In the study of opportunistic network, the design of mobile model directly affects the architecture of opportunistic network and the efficiency of routing algorithm. On the discussion of human movement characteristics, this paper analyzed the characteristics of students' movement in campus environment and presented a campus mobile model based on periodic purpose, Periodical-Purpose Campus Mobility...
In order to alleviate the mobile data explosion problem, a Wi-Fi offloading strategy has been proposed. Given the recent deployment of Wi-Fi like systems in the TVWS (TV White Space), the mobile offloading to White-Fi networks is an attractive solution to mobile operators to provide full broadband coverage in dense urban environments. To quantify the amount of throughput and coverage gain achieved...
A highly interesting trend in mobile network optimization is to exploit knowledge of future network capacity to allow mobile terminals to prefetch data when signal quality is high and to refrain from communication when signal quality is low. While this approach offers remarkable benefits, it relies on the availability of a reliable forecast of system conditions. This paper focuses on the reliability...
Nodes in a mobile Ad Hoc network can change their location dynamically. The manner in which nodes can be moved can be represented by a mobility model. A mobility model defines the speed, pauses and direction of the nodes in a network. The way in which nodes move in an emergency scenario and rescue differs from a normal scenario, because the normal paths can be interrupted. AVM mobility models and...
In recent years a new concept, called “mobile cloud computing” (MCC), has been put forward, it can build more powerful mobile cloud applications, and it is considered as one of the most highly discussed topics in terms of both academic community and computing industry. In this paper, we aim to understand why mobile computing chooses cloud computing as an external source. Thus, this paper presents...
Mobile cloud computing (MCC) has been proposed to offload heavy computing jobs of mobile devices to cloud servers managed by cloud service provider (CSP), which enables the mobile devices to save energy and processing delay. Heretofore, cloud offloading policies in mobile devices and pricing/scheduling in CSP have been independently addressed. This paper is first to jointly account for both sides...
Major interest is currently given to the integration of clusters of virtualization servers, also referred to as ‘cloudlets’, into the access network to allow higher performance and reliability in the access to mobile cloud services. We tackle the cloudlet network design problem for mobile access networks. The model is such that virtual machines are associated with mobile users and are allocated to...
