With recent advancement in mobile communication, there has been a rise in the number of applications for mobile and its users are also continuously growing throughout the universe. Most of the applications developed, are for en-tertainment and internet. Apart from this many of the utilities have been devel-oped to make handing of mobile devices easy. Numbers of people using mobiles and wireless devices are growing rapidly, but still mobile application market isn’t growing at the expected rate. Number of people having mobile are far more than people having computer or laptop. And if we provide application for mobile that will assist people in their day-to-day routine and official work, it can become a po-tential area of development. Considering the ubiquity wireless devices and their ability to be used anywhere and at any time, this paper presents a platform for the intercommunication between applications and load balancing access of dis-tributed LAN servers with implementation issues of application development. © Institute for Computer Sciences, Social Informatics and Telecommunications Engineering 2013.

Scene text detection is an important task in computer vision. Many previous work require multi-step processing and are not robust against challenges, such as small-scales and blurring. In this paper, we propose a Multi-level Feature extraction Network (MLFN), which can capture more detailed information and is easy to train. We embed MLFN into the middle of an end-to-end network and achieve a better accuracy and robustness. the experiment results on ICDAR 2011 and ICDAR 2013 further demonstrate the effectiveness of our method. © Springer Nature Singapore Pte Ltd. 2018.

Traditional Virtual Machine Monitor (VMM) virtualizes some devices and instructions, which induces performance overhead to guest operating systems. Furthermore, the virtualization contributes a large amount of codes to VMM, which makes a VMM prone to bugs and vulnerabilities. On the other hand, in cloud computing, cloud service provider configures virtual machines based on requirements which are specified by customers in advance. As resources in a multi-core server increase to more than adequate in the future, virtualization is not necessary although it provides convenience for cloud computing. Based on the above observations, this paper presents an alternative way for constructing a VMM: configuring a booting interface instead of virtualization technology. A lightweight virtual machine monitor - OSV is proposed based on this idea. OSV can host multiple full functional Linux kernels with little performance overhead. there are only 6 hyper-calls in OSV. the Linux running on top of OSV is intercepted only for the inter-processor interrupts. the resource isolation is implemented with hardware-assist virtualization. the resource sharing is controlled by distributed protocols embedded in current operating systems. We implement a prototype of OSV on AMD Opteron processor based 32-core servers with SVM and cache-coherent NUMA architectures. OSV can host up to 8 Linux kernels on the server with less than 10 lines of code modifications to Linux kernel. OSV has about 8000 lines of code which can be easily tuned and debugged. the experiment results show that OSV VMM has 23.7% performance improvement compared with Xen VMM.

Wireless community networks are wireless mesh networks created and managed by a local community with mainly two main goals: sharing internet connection and supporting local services. they are an emerging trend in Europe and have received the attention of many researchers, since they are large accessible deployments of distributed wireless networks. this paper illustrates the features of the Rome-based Ninux community network, the largest in Italy, and studies some interesting features it offers related to routing metrics and centrality metrics.

DDoS attack detection algorithms based on entropy computing

distributed Denial of Service (DDoS) attack poses a severe threat to the internet. It is difficult to find the exact signature of attacking. Moreover, it is hard to distinguish the difference of an unusual high volume of traffic which is caused by the attack or occurs when a huge number of users occasionally access the target machine at the same time. the entropy detection method is an effective method to detect the DDoS attack. It is mainly used to calculate the distribution randomness of some attributes in the network packets' headers. In this paper, we focus on the detection technology of DDoS attack. We improve the previous entropy detection algorithm, and propose two enhanced detection methods based on cumulative entropy and time, respectively. Experiment results show that these methods could lead to more accurate and effective DDoS detection. © Springer-Verlag Berlin Heidelberg 2007.

the increasing use of wireless internet and smartphone has accelerated the need for widespread computing. Smartphones stimulate growth of Global Position Systems (GPS) and mobile cloud computing. Mobile cloud computing is the cloud infrastructure where the computation and storage are moved away from mobile devices. However, smartphone mobile computing poses challenges because of the limited battery capacity, constraints of wireless networks and the limitations of device. therefore, it is necessary to offload the computation-intensive part by careful partitioning of application functions across a cloud. Mobile applications can be executed in the mobile device or offloaded to the cloud clone for execution, in this paper;we propose a new elastic application model that enables transparent use of cloud resources to augment the capability of resource constrained mobile devices. the significant features of this model include the partition of a single application into multiple components. Its execution location is transparent it can be run on a mobile device or migrated to the cloud. thus, an elastic application can augment the capabilities of a mobile device including computation power, storage, and network bandwidth, with the light of dynamic execution configuration according to device's status including CPU load, memory, battery level. We demonstrate promising results of the proposed application model using data collected from one of our example elastic applications. © 2013 IEEE.

Aiming at the problem of access control in distributed computing security model, a secure Seal calculus based on hybrid type detection is proposed. In order to realize the security policy that low security level information in the multi-level security system can only flow to equal or higher security levels, it establishes a security system with security level for Seal calculus, and uses static type detection to realize fine particle size access control efficiently. To solve the practical problems of channel control and security power reduction, an effective dynamic transformation framework based on mandatory type transformation is proposed. the static detection and dynamic detection are organically integrated to form a unified security model, which can not only guarantee the security of distribute computing, but also have good availability. © Springer Nature Singapore Pte Ltd 2018.

In scenarios like the surveillance of isolated areas, when the border node of a network does not have a permanent connection with the internet, Wireless Sensor Networks (WSNs) are calling for resilient in-network data storage techniques which minimize the risk of data loss. the efficiency of these techniques can be largely improved exploiting information on the status of the network, such as that used by routing protocols. In particular, one of the most used protocol in internet of things (IoT) scenarios is the IPv6 Routing Protocol for Low power and lossy networks (RPL). In this paper, we propose a redundant distributed data storage and retrieval mechanism to increase the resilience and storage capacity of a RPL-based WSN against local memory shortage. We evaluate our approach in the Contiki operating system through extensive analysis with the Cooja simulator.
