With the effects of global warming, some epidemic diseases via mosquito (e.g. mosquito-borne diseases) become more serious, such as dengue fever and zika virus. It is reported that the epidemic disease may cause many challenges to the hospital management due to the unexpected burst with uncertain reasons. Furthermore, the imperfect cares during the propagation of epidemic diseases, such as dengue...
Resource allocation efficiency and energy consumption are among the top concerns to today's Cloud data center. Finding the optimal point where users' multiple job requests can be accomplished timely with minimum electricity and hardware cost is one of the key factors for system designers and managers to optimize the system configurations. Understanding the characteristics of the distribution of user...
Full-motion video (FMV) target tracking requires the objects of interest be detected in a continuous video stream. Maintaining a stable track can be challenging as target attributes change over time, frame-rates can vary, and image alignment errors may drift. As such, optimizing FMV target tracking performance to address dynamic scenarios is critical. Many target tracking algorithms do not take advantage...
Distributed Estimation scheme has been widely used in sensor networks. Through various approaches, sum of bits, Sigma-Delta modulation, and source coding, this paper implements the above techniques for distributed estimation and provides a new one called Quantization Region Allocation. In the end, this paper analyzes the performance (minimum mean squared error) and demonstrates performance approximating...
For M2M (Machine-to-Machine) machines in cellular networks, employing high transmission rates or transmitting in large power actually cost them much energy. This is harmful to the machines, especially they are operated by batteries. The Relay Node (RN) in Long-Term Evolution-Advanced (LTE-A) networks is used to enhance the coverage of high data rate and solve the coverage hole problem. Considering...
It is significant to apply load-balancing strategy to improve the performance and reliability of resource in data centers. One of the challenging scheduling problems in Cloud data centers is to take the allocation and migration of reconfigurable virtual machines (VMs) as well as the integrated features of hosting physical machines (PMs) into consideration. In the reservation model, workload of data...
Nowadays, enterprises face many challenges of cyber security. How to efficiently allocate defensive resources to reduce damages which are caused by cyber attackers and evaluate system survivability to keeping services operating became important issues. Hence, we develop a scenario of that both cyber attacker and network defender are with incompletely understanding the information about each other...
Heterogeneous networks (HetNets) are expected to be one of the major performance enhancement enablers of LTE-Advanced. In order to protect pico-UEs from the strong macro interference, the macro eNBs need to reduce the transmission power during protected subframes instead of suspending data transmission introduced in 3GPP Release 10, scheduling strictly users in the vicinity of the macro eNBs. In this...
Joint energy saving resource allocation and user scheduling scheme in orthogonal frequency division multiple access (OFDMA) relay networks is considered. Different from allocating resources for users, we allocate resources for packets in the priority queue. Before resource allocation, a scheduling scheme is carried out to assign different priorities to the packets in the queue to guarantee the fairness...
By incorporating relay technologies into cellular systems, multi-hop relay networks (MRNs) can provide higher throughput and wider coverage, but it is impossible to guarantee quality of service (QoS) requirements for users at the cell edge and in hot spots due to severe co-channel interference (CCI) and load imbalance. This paper proposes an adaptive resource allocation scheme with a joint consideration...
One of the goals of information security education is to develop students' skills to solve unseen security vulnerability with contemporary methodologies. This paper presents the teaching of a new algorithm on resource allocation of network attack and defense with mathematical programming for evaluating the network survivability. Adopting a scaffolding technique, students take up a role of a defender...
In the OFDMA-based cellular relay networks, relay selection and resource allocation are the main problem to be solved. Many present works about resource allocation are for the goal of throughput maximization. In this paper, we propose an adaptive resources allocation algorithm joint relay selection, sub-carrier assignment and power allocation for the goal of energy saving to ensure users' QoS, and...
In cloud computing, computational resources are provided to remote users in the form of leases. For a cloud user, he/she can request multiple cloud services simultaneously. In this case, parallel processing in the cloud system can improve the performance. When applying parallel processing in cloud computing, it is necessary to implement a mechanism to allocate resource and schedule the tasks execution...
During the process of the wholesale, in different power grid gate, the wholesale power capacity requires different provincial power network lines and different usages of the resources of the transformation of electric energy; hence it has some influences on the cost of power transmission and distribution which was operated by the provincial power company who allocated the wholesale power correlated...
In this paper, we present for mobile ad hoc networks an efficient distributed address allocation protocol which is immune to topology changes caused by node's mobility. Contrary to the common belief that mobility makes protocol design more difficult, we show that node's mobility can, in fact, be useful to provide efficient address allocation in ad hoc networks. In our protocol, each node that has...
Multi-core architecture provides more on-chip parallelism and powerful computational capability. It helps virtualization achieve scalable performance. KVM (kernel based virtual machine) is different from other virtualization solutions which can make use of the Linux kernel components such as completely fair scheduler (CFS). However, CFS treats the KVM threads as normal tasks without considering about...
Most researches regarding home automation technologies were focusing on ??high-performance?? or ??human-centered?? automation systems. However, even though the ??human-centered?? systems have been developed for years, it is still far from being accepted by consumers. One of the major problems is that the technology development actually ignored the most important portion: the human nature. In this...
The E-MBMS (evolved multimedia broadcast and multicast service) in 3GPP LTE is characterized by the MBSFN (MBMS single frequency network) operation. The MBSFN operation requires that the identical signals are transmitted from all the base stations at the same time and in the same frequency. Such requirement implies some restrictions in the resource allocation and may increase the needed bandwidth...
