Internet of Things combined with social networks, has emerged as an interesting research area which is referred to as Social Internet of Things (SIoT). Objects in SIoT interact with each other based on their social behavior. In this ...

In many real world situations, data are updated and released over time. In sequential data publishing, the number of attributes and records may vary and the attribute values may be modified in different releases. This might lead to a compromise in ...

In the Cloudlet architecture of Mobile Cloud Computing (MCC), a mobile device, in order to overcome its lack of resources, offloads resource-intensive tasks on a nearby and self-managed cloud-based data center (i.e., cloudlet). In this architecture, a ...

In the cloudlet architecture of mobile cloud computing (MCC), the mobile users offload their resource-intensive tasks to a local cloud (i.e., Cloudlet) via WiFi connections, to overcome the resource-constrained nature of mobile devices. The users of ...

Mobile Cloud Computing (MCC) is an emerging technology to overcome the resource-constrained nature of mobile devices by offloading the resource-intensive operations to cloud-based data centers. The characteristics of MCC, including the mobility, the ...

Recent advances in Unmanned Aerial Vehicle (UAV) technologies have enhanced Wireless Sensor Networks (WSNs) by offering a UAV as a mobile data gathering node. These systems are called WSN-UAV that are well-suited for remote monitoring and emergency ...

In a multi-hop sensor network, sensors largely rely on other nodes as a traffic relay to communicate with targets that are not reachable by one hop. Depending on the topology and position of nodes, some sensors receive more relaying traffic and lose ...

We define a privacy model based on k-anonymity and one of its strong refinements to prevent the background knowledge attack.We propose two hierarchical anonymization algorithm to satisfy our privacy model.Our algorithms outperform the state-of the art ...

The characteristics of mobile cloud computing (MCC) including, mobility, the instability of 3G/WiFi connections, and the complexity of virtualization, make the prediction of performance challenging. To deal with these issues, an analytical performance ...

Display Omitted We propose a game for reducing power consumption in data centers.We show that the game always converges to a pure Nash equilibrium.We establish upper bounds on the convergence time of the game.We prove that PoA=1.23.We show that PoS1. ...

Creation of hot-spots is unavoidable, in multihop wireless sensor networks using the least power (or shortest path) routing method. This happens due to the irregularity of underlying network structures. Since hot-spots lose their energy faster than ...

Memory access scheduling is an effective manner to improve performance of Chip Multi-Processors (CMPs) by taking advantage of the timing characteristics of a DRAM. A memory access scheduler can subdivide resources utilization (banks and rows) to ...

In wireless ad hoc networks, there is no infrastructure to enforce cooperation between nodes. As a result, nodes may act selfishly when running network protocols to conserve their energy resources as much as possible. In this paper, we consider the "...

Delay Tolerant Networks (DTNs) suffer from frequent disruptions and partitioning. Because of dynamic environment and lack of knowledge about the whole network topology, routing is quiet challenging in DTNs. Prediction based algorithms in DTNs are able ...

Positive Influence Dominating Set (PIDS) has applications in Online Social Networks (OSN) such as Viral Marketing and College Drinking Problem. To many reasons finding Minimum PIDS (MPIDS) is very desirable. Beside, one of the most important features ...

Reliability is one of the important issues in the design of distributed computing systems (DCSs). This paper deals with the problem of task allocation in heterogeneous DCSs for maximizing system reliability with several resource constraints. Memory ...

Data aggregation in wireless sensor networks (WSNs) is known as a method of energy saving through reducing the number of communications. Due to the failure-prone nature of communications in WSNs caused by harsh environments, fault-tolerant aggregation ...

In wireless ad hoc networks there is no fixed infrastructure or centralized controller to enforce cooperation between nodes. Therefore, nodes may act selfishly in running network protocols for conserving their own energy resources. In this paper, we ...

Increasing amount of data and demand to process and analyze them induces enterprises to employ alternative computing paradigms to overcome computing capacity shortages. Cloud Computing is a new emerged computing approach that promises scalability of ...
