We present the first selectively secure hierarchical identity-based non-interactive key agreement (HIB-NIKA) in the standard model that does not explicitly require multilinear maps. We give a novel solution for resilience called "shadowing factor" to improve the security of HIB-NIKA and present a practical attack model of hierarchical key agreement to analyze the anti-forgery and anti-collusion...
Most of latency-sensitive mobile applications require computational resources provided through a cloud computing service. The problem of relying on cloud computing is that, sometimes, the physical locations of cloud servers are distant from mobile users and the communication latency is long. As a result, the concept of distributed cloud service, called mobile edge computing (MEC), is being introduced...
This paper puts forward a new trust model CTM (Credit Transfer Model) in the mobile P2P (Peer to Peer) network. Applying a hybrid P2P network topology structure, the CTM selects large servers in the cable network as super nodes which maintain the identity information, resource information, transaction records and trust information of ordinary nodes. The CTM simplifies the calculation of the node's...
Immediately after a disaster, the normal telecommunication infrastructure, including wired and wireless networks, is often seriously compromised and cannot guarantee regular coverage and reliable communications services. These temporarily-missing communications capabilities are crucial to rescuers and affected citizens as the responders need to effectively coordinate and communicate to minimize the...
The paradigm of health care delivery is slowly aligning with the needs and habits of modern patients. Mobile computing may be a solution to respond to the growing trend and need for health care sharing and collaboration, enabling the redesign of processes giving rise to new models of health care delivery. Seeking to determine the situation in Portugal regarding mobile computing initiatives in this...
High frequency bands are considered for the fifth generation (5G) mobile networks to handle the continuous increase in the demand for cellular data traffic. However, the propagation conditions in high frequency bands are more challenging than in low frequency bands, making the radio link more susceptible to obstruction. These new radio aspects impose new challenges on the design of user mobility procedures...
With the fast development of the cloud computing and virtualization techniques, computation resources can be allocated more dynamically and scalably on demand. This paper aims to study two types of computing, i.e., service computing and communication computing. We have proposed to have both computing resource in mobile operator's mobile cloud and investigated how to jointly allocate them with the...
The 5G mobile network is expected to meet the diverse demands from multiple types of business services. At the same time, some of the 5G use cases come with hard, and often expensive to meet, requirements in terms of latency and bandwidth. It is a common understanding that one system can not fit all and there is a need for customizing network according to the requirements of specific business use...
We have presented the real time database management in mobile computing system and supported by mobile computing system. The process of the system including various mobile system those are wireless network, the database management, disconnection.
Provides an abstract for each of the presentations and may include a brief professional biography of each presenter. The complete presentations were not made available for publication as part of the conference proceedings.
The growth of Mobile cloud computing (MCC) is challenged by the need to adapt to the resources and environment available for mobile clients while working with the dynamic changes of network bandwidth. In this paper, we propose a model of computation partitioning for stateful data in the dynamic environment that will improve performance. First, we constructed a model of stateful data streaming and...
Mobile cloud computing is a wide-ranging blend of cloud computing and mobile development. It is a technique in which mobile applications are assembled, functioned and presented using cloud computing technology. The hastening in the advancement of cloud computing as well as mobile computing has led to the invention of an amalgamated output: Mobile Cloud Computing. These days, this is becoming one of...
Although Deep Neural Networks (DNN) are ubiquitously utilized in many applications, it is generally difficult to deploy DNNs on resource-constrained devices, e.g., mobile platforms. Some existing attempts mainly focus on client-server computing paradigm or DNN model compression, which require either infrastructure supports or special training phases, respectively. In this work, we propose MoDNN —...
Social context is important to a variety of significant applications such as business intelligence, public security and epidemic. For example, companies can refine the advertisement strategy by targeting the influential people within the social group. Social context modelling and recognition is an emerging research area which aims to infer the information that characterizes multiple users such as...
Emerging augmented reality devices allow for visualizing results of numerical simulations ubiquitously. This enables decision makers and engineers in the field to make better decisions. However, computation of resource-intensive simulation models on resource-poor and battery-powered mobile devices requires to drastically reduce the quality of the simulation. We therefore proposed approaches utilizing...
Mobile Ad-hoc Networks are dynamic in nature and do not have fixed infrastructure to control nodes in the networks. The challenge lies ahead in coordinating among such dynamically moving nodes. Over a due course, nodes might become selfish and may refrain from packet forwarding because of the heavy dynamism. This selfish behavior might also result as an impact of malicious nodes in the neighborhood...
An Ad hoc network is frequently changing their network structures and no need of any fixed infrastructure based network. Mobility model is one of the important key problems in Mobile Ad hoc Networks (MANETs) due to changing node position frequently in simulation area. In Group mobility models each group has a leader, rest of the group nodes follow the leader node. Angle and Speed are two essential...
The use of recommendation in trust-based models has its advantages in enhancing the correctness and quality of the rating provided by mobile and autonomous nodes in MANETs. However, building a trust model with a recommender system in dynamic and distributed networks is a challenging problem due to the risk of dishonest recommendations. Dealing with dishonest recommendations can result in the additional...
In this paper, we propose topology based adaptive hybrid multicast routing (THMR) mechanism in mobile ad hoc networks. With the help of technique derived from Computational Intelligence (CI) discipline, Topology Change Rate (TCR) is predicted based on link behavior and node mobility for both proactive and reactive routing region in MANETs. We design a Reinforcement Learning (LR) based Q-Learning (QL)...
Cloud computing is a very important feature in which application resources are provided over the internet as a service to users that discovering its utilization all over. Mobile Cloud Computing (MCC) combines the features of mobile computing and cloud computing for improving performance.
