With the enhancement in technical field of communication, efforts are made by the researchers to provide security. Security is dispensing protection and privacy to the system for the channeled data against any unwarranted access and refinements. MANET is a variant of wireless network used essentially by the dynamic devices with high motility and vulnerability. The distinctions like dynamic layout and curbed resources make them susceptible to miscellaneous kinds of threats. One such attack is wormhole which sneak and peep data with malicious intensions and operates either in coordinated or uncoordinated fashion. In its coordinated version, the malicious nodes coordinate their operations whereas in the uncoordinated version; they operate solitarily with the aim to decline the network performance. In this work, we aim to propose an algorithm for deployment of wormhole attack communicating with its peer through a tunnel. Planting of this attack in the network lays the foundation for developing successful strategies to mitigate their effects on the system.

The routing security issues of MANETs are described. The Black hole attack, which can easily be deployed against MANET and an efficient technique to isolate the multiple black hole attack, is described. The proposed technique will be based on to analyze the route reply packets in which the nodes reply with the exceptional high sequence number is add into blacklist. To isolate these nodes from the network, technique of clustering will be applied this improvement leads to increase network performance. The future work may be concentrate on the proposed technique can be compared with some other technique of intrusion detection for mobile ad-hoc networks. And also the proposed technique can be applied for the detection of wormhole attack in the network. The malicious nodes which are increasing delay in the network.

Wireless security is the prevention of unauthorized access to computers using wireless networks .The trends in wireless networks over the last few years is same as growth of internet. Wireless networks have reduced the human intervention for accessing data at various sites .It is achieved by replacing wired infrastructure with wireless infrastructure. Some of the key challenges in wireless networks are Signal weakening, movement, increase data rate, minimizing size and cost, security of user and QoS (Quality of service) parameters... The goal of this paper is to minimize challenges that are in way of our understanding of wireless network and wireless network performance.

Vehicular networks or VANET announce as the communication networks of the future, where the mobility is the main idea. These networks should be able to interconnect vehicles. The optimal goal is that these networks will contribute to safer roads and more effective in the future by providing timely information to drivers and concerned authorities. They are therefore vulnerable to many types of attacks among them the black hole attack. In this attack, a malicious node disseminates spurious replies for any route discovery in order to monopolize all data communication and deteriorate network performance. Many studies have focused on detecting and isolating malicious nodes in VANET. In this paper, the authors present two mechanisms to detect this attack. The main goal is detecting as well as bypass cooperative black hole attack. The authors' approaches have been evaluated by the detailed simulation study with NS2 and the simulation results shows an improvement of protocol performance.

Mobility Performance

  Over the last decade, wireless devices have developed rapidly until predictions will develop with high complexity and dynamic. So that new capabilities are needed for wireless problems in this problem. Software Defined Network (SDN) is generally a wire-based network, but to meet the needs of users in terms of its implementation, it has begun to introduce a Wireless-based SDN called Software Defined Wireless Network (SDWN) which provides good service quality and reach and higher tools, so as to be able to provide new capabilities to wireless in a high complexity and very dynamic. When SDN is implemented in a wireless network it will require a routing solution that chooses paths due to network complexity. In this paper, SDWN is tested by being applied to mesh topologies of 4,6 and 8 access points (AP) because this topology is very often used in wireless-based networks. To improve network performance, Dijkstra's algorithm is added with the user mobility scheme used is RandomDirection. The Dijkstra algorithm was chosen because it is very effective compared to other algorithms. The performance measured in this study is Quality of Service (QoS), which is a parameter that indicates the quality of data packets in a network. The measurement results obtained show that the QoS value in this study meets the parameters considered by the ITU-T G1010 with a delay value of 1.3 ms for data services and packet loss below 0.1%. When compared with the ITU-T standard, the delay and packet loss fall into the very good category.
