This work is based on UMTS mobility, which is adopted by the S1 interface, with a level 3 Mobile IPv6 (MIPv6) in addition the new program with C ++, by the use of Session Initiation Protocol (SIP) between two end users to evaluate the performances of UMTS networks with the SDN paradigm. SDN is a program running on one or more nodes of the network. It will calculate the routes to be taken by incoming packets in the network and will then communicate them to all virtual switches.

This paper presents the performance evaluation of QoS parameters such as gigue, latency, lost packets, end-to-end delay, MOS under Omnet 4.6++ for all types of Software Defined Networking (SDN) topologies “Hierarchical, star, ring, tree”, in order to determine the architecture most suitable for the latter, via the implementation and simulation of the OpenFlow protocol.

SDN (Software Defined Network) has completely changed the network architecture in terms of quality of service .In this respect, this article is a comparative study between the two architectures: SDN and Ethernet under Omnet4.6++, to determine the most appropriate technology. Software-Defined Networking (SDN) is an idea which has recently reignited the interest of network researchers for programmable networks and shifted the attention of the networking community to this topic by promising to make the process of designing and managing networks more innovative and simplified compared to the well-established but inflexible current approach.

Routing data among wireless routers becomes a challenging issue as traditional routing algorithms, which cannot fulfill the requirements of distributed communications in Smart Cities. The routing decisions are taken based on local knowledge of a wireless router about each of its neighbors to reflect a partial visibility of the network. Such a local visibility limits the ability of managing the huge number of wireless smart devices in Smart Cities. An attractive alternative is the Software Defined Networking (SDN), which offers a centralized view of the entire network by refactoring the wireless protocols into control and forwarding decisions. However, many challenges must first be overcome to realize this potential. In this paper we describe: OpenSDWN Architecture, Programmable Datapath, Wireless Monitoring using SDN-WIFI solution.

Software SDN is the evolving network concept, which makes possible the automation of control and services development. Its main advantages are the centralized global network view, programmability, and separation management of the data plane as well as the control plane. These features have got attention of researchers to improve the QoS of today’s various network applications. We aim to make a picture of QOS based on OpenFlow for SDN networks. The main goal of this paper is to present a comparison of SDN and Hardware Defined Network (HDN) in terms of QoS metrics like latency by using a POX Controller.

Thus, the total of traffic accidents over the past year amounted to 81827 against 78864 in 2015, an increase of 3.76%, according to provisional statistics of traffic accidents in 2016. These statistics show that Morocco is one of the countries with the highest mortality rate. In order to decrease these numbers and put an end to this dilemma, we are working on developing vehicle-to-vehicle communication (V2V) in order to provide information and assistance required to avoid collisions, traffic-jam, etc. Vehicular Ad-Hoc Networks (VANETs) have great potential for providing safety and comfort applications for Intelligent Transport Systems (ITS) and to improve traffic safety on roads. In this paper, we have consecrated our study on Casablanca, the largest city in Morocco which has a highway passing through it. Thus, we took two scenarios, first the highway and trunk roads and second the other roads (primary, secondary, tertiary and residential roads). To demonstrate these scenarios, we used various tools such as OpenStreetMap and SUMO to generate a realistic mobility model that gives aspects of real vehicular traffic. Generated scenarios are added to NS-2.35 (Network Simulator) in order to analyze the performance of 802.11a (Wi-Fi) and 802.11p (DSRC/WAVE). We evaluated the performance based on three parameters: Packet Delivery Ratio, End-To-End Delay and Throughput. The results showed that 802.11p is better and more efficient than 802.11a under both scenarios. In addition, 802.11p gives better results in the second scenario than in the first one, and this is due to the number of cars, the authorized speed and the distance between the cars in each scenario.

Each of these has its own technology constraints. For VoIP, it is very important to take into consideration the need to provide a high quality service according to well-defined standard transmission (jitter, end-to-end delay, MOS, and packet loss). However, wireless networks (IEEE 802.11) are based on radio which undergoes a number of technical constraints to achieve theoretical transmission rates; among these constraints the number of users of the networks, the distance between the client and the access, and the amount of data transmitted point are included. In this term, a study is made by simulating wireless network in OPNET Modeler with a fairly large number of VoIPs (15 users) whose signaling is handled via a new node that was created specifically to manage the signaling tasks under SIP and H.323 in order to minimize the number of nodes in the network and avoid the congestion.

VoIP (Voice over Internet Protocol) is an emerging technology for voice communication which deploys many techniques to produce a high-quality service. Signaling is one of success keys of Voice over IP; the two most promised approaches in this case are H.323 and SIP. This paper draws a comparison between the four combinations of H.323 and SIP (Session Initiation Protocol), G .711 and G.729 (each combination includes one protocol and one hybrid codec) using a powerful network simulation tool (OPNET Modeler) which enables network simulation by employing various protocols. The combination H.323 and G.729 proved to be the most appropriate one in the connection process.

To display these competences, OPNET Modeler is an available simulator which evaluates every network environment and tells which scenario is the most suitable. In this developed tool, it is possible to implement voice over IP (Voip) networks with a great management of signaling parameters. However, in OPNET Modeler, there is no model node which offers the possibility to operate networks that support two different signaling protocols (session initiation protocol “SIP” and H.323) in the same time. In this paper a deep study of signaling protocols is conducted together with modifications made to create a new device encompassing proxy to support SIP and gatekeeper to establish H.323 calls in the same scenario.

IGMP protocol is the control mechanism used to control the delivery of multicast traffic to interested and authorized users. IGMP commands notify the upstream equipment to stop sending ("leave") one channel or begin sending ("join") another channel. Depending on the architectural choices, this process occurs in the DSLAM, an aggregation switch, or at an edge router. All channels are sent by a multicast source to DSLAM even if no user in the DSLAM has requested it. This leads to sub-optimal use of bandwidth. This paper studies and investigates the performance of IPTV controlled by CGMP Protocol to save bandwidth using OPNET package. It shows that when CGMP is enabled on edge routers and switches, hosts receive only the channels demanded and therefore the bandwidth is optimized and also the queuing delay is reduced.

Therefore we must find the best ways to protect our IT system from these attacks. Researchers have proposed different methods and algorithms to improve intrusion detection systems (IDS). There are different types of these systems and all of them are suffering from a common problem which is generating an important number of alerts and huge volume of false positives. This disadvantage has become the main motivation for many researchers in IDS area. The aim of conducted research in this field is to propose different techniques to handle the alerts, to reduce them and distinguish real attacks from false positives and low importance events. This paper is a survey that represents a review of the current research related to the false positives problem. The focus will be on alert correlation and data mining techniques to reduce false positives.
