In SDN, control plane and data plane are decoupled which justifies the need to have a central controller to receive the application requirements (e.g. Quality of Service requirements) and implements a set of network policies on the data plane to eventually satisfy the requirements of the application. Implementing a proper set of policies on data plane can be quite a challenging task. In many cases implementing a set of policies in order to satisfy the requirements of an application negates requirements of other applications. In this paper, a simulation study is conducted to evaluate the performance of a QoS policy (i.e. reserving bandwidth) on a specific type of multimedia traffic (e.g. video, audio and data) and its influences on other types of multimedia traffic. The outcome of the simulation study has motivated the authors to conduct a mathematical analysis on the sensitivity of network applications over all possible combination of network policies to eventually implement a proper set of policies that imposes minimum destructive impact on other network applications or services.","PeriodicalId":190994,"journal":{"name":"Netw.

Monitoring a given area is one of the main goals of this technology. This consists in deploying sensor nodes in the Area of Interest (AoI) in order to detect any event occurring in this area, collect information and send them to the base station. However, in this type of configuration, the quantity and the quality of data collected are important factors in making better decisions by the end user. It therefore becomes crucial to deploy sensors in the AoI so that the latters can cover as much as possible the AoI, and propose mechanism to collect and send data to the base station while minimizing the energy consumption of the sensors. In this paper, we bring into focus a solution (A2CDC) to resolve this problem which performs in two main stages: in the first stage, we propose an algorithm that guarantees a maximal coverage of the AoI after a random deployment of static sensors and mobile sensors; and in the second stage, we propose a node activity scheduling that minimizes energy consumption of both static and mobile nodes while sending collected data to the base station. Compared to many other algorithms in the literature, our solution is better in term of coverage percentage of the AoI, data received by the base station and in term of energy minimization.","PeriodicalId":190994,"journal":{"name":"Netw.

They form a multi-hop communication network. The scatternets formed with Bluetooth protocol is a communication solution. However, there is no current algorithm that considers the different capabilities of the devices (sensors or actuators) and assigns a role according to these capabilities. In this paper, we present a network topology formation algorithm for role assignment and connection establishment which considers the capabilities of the devices and use slave-slave Bridge to communicate the piconets. We design the algorithms needed for this protocol and test it. We have simulated the algorithms in order to evaluate the time needed for role assignment and to establish the first connections of the piconet. The results include different scenarios composed by one or two masters and one to seven slaves. In addition, we evaluate the established connections in piconets and bridges in a real case of the smart garden sensor network. Finally, we present the changes in the piconet connections after the deployment of two nodes in an existing network.","PeriodicalId":190994,"journal":{"name":"Netw. Protoc.

This document lists some of the limitations existing in WSN networks. In addition, several existing techniques are collected to maximize the network's lifetime, demonstrating that efficient use of energy is very important to achieve this goal. Due to the importance of knowing the behaviour of this type of network before its launch, a comparative is established for the options offered by the WSN network simulators available in the market, compared to those offered by CupCarbon. The objective of this project is the evaluation of the CupCarbon simulator through the implementation of an algorithm that aims to maximize the life time of the network, as well as collecting the results offered by this algorithm. In this way, a Dijkstra routing algorithm is developed whose selection of routes depends on the battery level contained in the nodes that constitute the network. This algorithm is referred as dynamic Dijkstra in the present document. To achieve the objectives described, we pretend to simulate the dynamic Dijkstra in CupCarbon, for this aim, the source code is modified, since it is a free code tool. As a result, it is possible to create the original Dijkstra, but certain problems are presented, to develop the part that depends on the energy, related to the functionalities offered by CupCarbon. As an alternative to determine the results associated to the created algorithm, theoretical analyses are accomplished. Consequently, it is concluded that the evaluation of CupCarbon is not satisfactory enough, while the algorithm created maximizes the network's lifetime.","PeriodicalId":190994,"journal":{"name":"Netw.
