Internet access by wireless networks has grownconsiderably in recent years. However, these networks are vulnerable to security problems, especially those related to denial of service attacks. Intrusion Detection Systems(IDS)are widely used to improve network security, but comparison among the several existing approaches is not a trivial task. This paperproposes building a datasetfor evaluating IDS in wireless environments. The data were captured in a real, operating network. We conducted tests using traditional IDS and achievedgreat results, which showed the effectiveness of our proposed approach.

Motif recognition is key to identify common sequences and specific elements recognized by different proteins such as Transcription Factors or RNA Binding Proteins. One interesting approach to computationally identify motifs consists on using additional sources of information besides the input sequences to guide the motif search. However, depending on the information and input data size the motif recovery process can take several hours. One of the most used algorithms for motif recovery is Priority [1]. This algorithm uses a Gibbs sampling strategy and includes additional information, in informative priors, to guide the motif search. We propose to reduce motif recovery processing time by using threads to execute independent processes in parallel. We apply the strategy to Priority and the results show the strategy has a positive effect on time and it does not affect the quality of the resultant motif. Reducing processing time in motif recovery algorithms is important considering that massive parallel sequencing is frequently used today. By using massive sequencing the number of sequences derived by experimental techniques is only getting bigger.

In this paper we present an outdoor smart parking prototype using wireless sensor networks as a possible solution to solve the problem of parking, through an application that present the information in order to find free parking spaces in real time, this system can help to improve the quality of life in smart cities, because the time for finding a free parking space could be reduced, as well as help to reduce pollution and to improve vehicular traffic. The use of a wireless sensor networks allow for easy installation outdoor, the system could use a solar panel to charge the batteries and being independent of an external power source wired or constantly replacing batteries. The vacancies spaces are presented to users through a smart device. The main results show a reduction of 50% of time to obtain a free parking space, a reduction in fuel consumption, and an estimated reduction of vehicle pollution. Finally, we determine for our campus university the fuel saved were 2,71 galons/year/vehicle.

Software-Defined Networks (SDNs) represents an innovative approach in the area of computer networks, since they propose a new model to control forwarding and routing data packets that navigate the World Wide Web. Since research on this topic is still in progress, there are not many devices such as routers and switches that implement SDN functionalities; moreover, the existing ones are very expensive. Thus, in order to make researchers able to do experiments and to test novel features of this new paradigm in practice at a low financial cost, one solution is to use virtual network emulators. As a result, this paper focuses on study and evaluation of SDN emulation tool called Mininet. Initial tests suggested that the capacity of rapid and simplified prototyping, the ensuring applicability, the possibility of sharing results and tools at zero cost are positive factors that help scientists boost their researches despite the limitations of the tool in relation to the performance fidelity between the simulated and the real environment. After presenting some concepts of this paradigm, the purpose of its appearance, its elements and how it works, some net prototypes are created to better understand the Mininet tool and an evaluation is done to demonstrate its advantages and disadvantages.

This paper tackles the problem of power allocation for each node in a Wireless Sensor Network (WSN) in order to maintain active communication links on a given area. Most of previous projects have concluded that the connectivity depends exclusively on the transmission power and the number of nodes per unit area, but they normally assign the same power for every node in the network. Our work proposes APA (Adjustable Power Allocation), a wise topology control algorithm that sets the sensitivity independently for each node in the network, in order to reduce the total power consumed by the network, still maintaining 100% of the nodes connected.

This paper presents a model for cellular communications infrastructure optimization considering its coexistence with an Advanced Measurement Infrastructure (AMI), using a strategy supported by a Cognitive Mobile Virtual Network Operator (C-MVNO). The goal is to ensure a secondary network operator is able to reuse the current communications infrastructure and use the same cellular telephony primary spectrum, but including a new user in the network, the so called Smart Meter, which is a fixed (non-mobile) user. The current work aims to the optimization of the cellular network base stations (BS) and of the interconnection links deployment by means of joining users in clusters defined by proximity and BS capacity. Thus, the model identifies the most suitable candidate sites for BS deployment and its partial-mesh optical-fiber interconnection network. It is included the links' traffic overhead analysis in order to decide the most suitable links as candidate for optimal optical network deployment. It is proposed a hybrid cellular-optical fiber design in order to permit the information reach the Measurement Data Management Systems (MDMS), which are placed in the centralized electric energy distribution offices, so to be processed and monitored.

This work presents the results of implementing a testbed for evaluating reference models of Internet of Things. There state-of-the-art platforms were tested: an open hardware platform, a commercial platform and a third one based on IPv6 architecture. According to these platforms three prototypes were developed based on the layers of the reference model of IoT, including the device layer, network, service and application layer. The main purpose was to show the remote management of devices through the concept of IoT performing monitoring and control tasks. In addition, we present an analysis of the architecture and performance comparison of the models in terms of the ease of deployment, device availability, network throughput, scalability and mobility.
