Abstract - A Mobile Ad-hoc NETwork (MANET) is formed by the connection of wireless devices without the aid of third party intervention, existing network infrastructure or applications. Many ideas and resources have been proposed to overcome some of the research challenges in MANETs but still many issues are left unsolved. Research work reveals that Ultra WideBand (UWB), a relatively new technology, when integrated with MANET at different layers of the network, will reduce some of the issues of MANETs in comparison to narrowband technology. UWB technology provides a method for transmitting a high frequency signal over a large amount of Radio Frequency (RF) spectrum whilst at the same time utilising minimal amounts of power in both the transmitting and receiving nodes. The most common and challenging issue in MANETs is the conservation of power. Although algorithms, models, and untested hypothesis have been proposed to enhance MAC protocols with respect to overhead delay, Quality of service and localisation yet a lot need to be done. This paper investigates the state of the art in MANETs under UWB with specific attention made to the MAC protocols and Routing. Based on the summary of existing work we have conducted, an algorithm will be developed, tested and verified, in order to optimise the performance of MANETs at the MAC layer as a future work. This paper reviewed the state of the art of MANET in respect of using UWB systems. |

Abstract - Controllers are fundamental elements for the implementation of a Software-Defined Network (SDN) application. The present work focusses on the problem of choosing the appropriate controller, for a specific use case, among the multiple solutions proposed by academia and industry. We here present a new method for controllers benchmarking, which allows finding the right controller for each use case in a systematic and rational manner. The Method is based on two steps: the first consists on classifying the controllers using a Multi-Criteria Decision Making method according to the relevance of their features for the use case. This step enables to limit considerably the number of potential controllers for the SDN application. In the second step, a performance evaluation is carried out using the CBENCH tool, where only the first three ranked controllers at the first step are considered. The method has been tested in the case of user traffic classification over SDN, where ten most known controllers were considered. The results showed that OpenDaylight (ODL) is the controller that responds the better to the constraints and requirements of this specific application. The method is generic and can be applied regardless of the SDN application. |

Abstract - For researchers of cybercrime one of the most complexes in addition to its detection is your check, these same characteristics and the circumstances of time and space in which they are made and, in most cases, by the intangibility of the evidence that must be collected and used to demonstrate its occurrence. These criminal offenses such as new forms are a reality in our time, by which different legal systems have had to cash them incorporating, not only prevent, but when judicializarlos can prove their commission. . |
