Traditional communication networks can be leveraged by separating controlling functions from forwarding functions using emerging technology known as Software Defined Networking (SDN). Though SDN has been around for some years, it was mostly limited to wired networks. Of late, it is being adapted to wireless networks. The programmable interface with decoupled controller can be used with MANET to integrate with other networks besides controlling it well. Both control and security are inevitable for the successful implementation of SDN in wireless networks. Towards this end, in this paper we implemented SDN based MANET for secure routing. Open Flow is used for implementing SDN controller while IDC is used for securing communications. Our framework is evaluated with NS3 simulations that reveal significant performance improvement when compared with traditional ad hoc networks that do not use SDN. This is achieved as SDN controller can quickly adapt to changed topologies due to node mobility.

Wireless networks are been used now-a-days. The most important fact about wireless network is it is mobile. It is thus used in many fields. One of the most important applications of wireless networks is Mobile Ad hoc NETwork (MANET) in which all the nodes work as both transmitter and receiver. MANETs are used in various fields like military, industry and emergency recovery. In order to provide adequate security against multiple attacks, the researchers are of the opinion that detection-based schemes should be incorporated in addition to traditionally used prevention techniques. Intrusion Detection and Prevention System (IDPS) is an effective defense mechanism that detects and prevents the security attacks at various levels. In recent work a polynomial key is employed for achieving useful key generation process and a polynomial is generated to compute the pair-wise key but it can be easily detected by the attacker so to improve the security in IDPS system, this work proposes the secure routing using Novel SEcured Keys Generation (NSEKG) against IDPS system. This proposal implements with two major keys: Secure Key (SeK) and Sharing key (ShK) creation is performed via the use of the User Property based Artificial Bee Colony (UPABC) algorithm and the frequency based behavior with certainty measurement on routing paths. These SeK and ShK keys creation with UPABC scheme exploits the encrypted value of the packets and the decryption determine whether the route reply is the result of a malicious node or not. The proposed NSEKG -IDPS system is very effective for communication attacks and needs to be gradually improved in order to detect multiple attacks. The performance is evaluated primarily in accordance with the subsequent metrics like Packet delivery ratio (PDR), Routing Overhead (RO), End-End-Delay (E2E), and Throughput

A mobile ad-hoc network is a method of communication between different nodes (mobile devices) without the use of base stations, which are used in wired networks. In a Mobile ad-hoc network, nodes can play the role of a receiver, sender, or a relay. As movement is flexible in Mobile ad-hoc networks and nodes have limited resources, nodes may join the communication or exit it at any time. Therefore, for Mobile ad-hoc networks, routing techniques - selecting communication routes and maintaining them – is considered important in an environment of constantly changing network topology. To overcome this problem, this paper proposes a reliable routing protocol based on MP-AOMDV, which monitors changes in signal strength not only for GPS signals but reception signals as well. Although MP-AOMDV was researched under the assumption of fixed movement direction and speed, this paper proposes a routing technique that works with changing movement direction or speed of nodes.

A Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using centralized access points, infrastructure, or centralized administration. Routing means the act of moving information across an internet work from a source to a destination. The biggest challenge in this kind of networks is to find a path between the communication end points, what is aggravated through the node mobility. In this paper we present a new routing algorithm for mobile, multi-hop ad-hoc networks. The protocol is based on swarm intelligence. Ant colony algorithms are a subset of swarm intelligence and consider the ability of simple ants to solve complex problems by cooperation. The introduced routing protocol is well adaptive, efficient and scalable. The main goal in the design of the protocol is to reduce the overhead for routing. We refer to the protocol as the Ant Colony Optimization Routing (ACOR).

Simulation Results

A Mobile Ad Hoc Network (MANET) suffers from high packet-loss due to various transmission impairments, such as: wireless signal attenuation, free space loss, thermal noise, atmospheric absorption, multipath effect, and refraction. All of these impairments are represented by a generic name, noise, and therefore such a network is referred to as a noisy network. For modeling and simulation purposes, the noisy environment is described by introducing a probability function, namely, the probability of reception (pc), which is defined as the probability that transmitted data is successfully delivered to its destination despite the presence of noise. This chapter describes the implementation and investigates the performance of the Threshold Secret Sharing (TSS) node authentication scheme in noisy MANETs. A number of simulations are performed using the MANET Simulator (MANSim) to estimate the authentication success ratio for various threshold secret shares, number of nodes, node speeds, and noise-levels. Simulation results demonstrate that, for a certain threshold secret share, the presence of noise inflicts a significant reduction in the authentication success ratio, while node mobility inflicts no or an insignificant effect. The outcomes of these simulations are important to facilitate efficient network management.

The Transmission Control Protocol (TCP) is a reliable protocol of transport layer which delivers data over unreliable networks. It was designed in the context of wired networks. Due to popularity of wireless communication it is made to extend TCP protocol to wireless environments where wired and wireless network can work smoothly. Although TCP work in wireless and wired-cum-wireless network, the performance is not up to the mark. In literature lot of protocols has been proposed to adopt TCP in wireless mobile ad hoc network. In this, we present an overall view on this issue and detailed discussion of the major factors involved. In addition, we survey the main proposals which aim at adapting TCP to mobile and static Ad hoc environments. Specifically, we show how TCP can be affected by mobility and its interaction with routing protocol in static and dynamic wireless ad hoc network.

Secured Communication

A mobile ad hoc network (MANETs) is an assortment of a variety of portable nodes that are linked collectively in a greater number in a wireless medium that has no permanent infrastructure. Here, all the nodes in the node partake in acting as both router and host and is in charge for accelerating packets to other nodes. This chapter discusses the various attacks on different layers and on various security protocols. So, designing a secure routing protocol is a main challenge in MANET. As we all know, this is a mobile ad hoc network so nodes in the network dynamically establish paths among each other so it is vulnerable to different kinds of threats. So, in this case, we need secured communication among the nodes present in the network.

A Vehicular Ad-Hoc Network, or VANET, is a form of Mobile Ad-Hoc Network to provide communications among nearby vehicles and between vehicles and nearby fixed equipments. Security has become a prime concern in providing communication between these vehicles. Unlike wired networks, the characteristics of Vehicular Ad Hoc Networks (VANETs) pose a number of non-trivial challenges to security design. In this paper, the authors present a threshold security mechanism with a mobility based Clustering for Open Inter Vehicle Communication Networks (COIN). Nodes that have a similar moving pattern are grouped into a cluster, and unlike other clustering algorithms, it takes the moving pattern of the vehicles into consideration with the driver’s intention. The stability of clusters is estimated based on relative mobility of cluster members. A threshold cryptographic scheme is employed on top of the clusters to protect routing information and data traffic. To ensure distributed trust in the clustered environment, the private key (k) is divided into n pieces in such a way that k is easily reconstructable from any p number of pieces.

Mobile wireless networks allow a more flexible communication structure than traditional networks. Wireless communication enables information transfer among a network of disconnected, and often mobile, users. Popular wireless networks such as mobile phone networks and wireless local area networks (LANs), are traditionally infrastructure based—that is, base stations (BSs), access points (APs), and servers are deployed before the network can be used. A mobile ad hoc network (MANET) consists of a group of mobile hosts that may communicate with each other without fixed wireless infrastructure. In contrast to conventional cellular systems, there is no master-slave relationship between nodes, such as base station to mobile users in ad-hoc networks. Communication between nodes can be supported by direct connection or multi-hop relays. The nodes have the responsibility of self-organizing so that the network is robust to the variations in network topology due to node mobility as well as the fluctuations of the signal quality in the wireless environment. All of these guarantee anywhere and anytime communication. Recently, mobile ad-hoc networks have been receiving increasing attention in both commercial and military applications.
