A mobile ad hoc network is a wireless network of mobile devices that communicate with one another without any fixed network infrastructure. Existing mobile ad hoc networks are either based on IEEE 802.11 a or b standard. Both standards provide limited bandwidth and therefore are not suitable for data intensive applications such as automated video surveillance. Wi-Fi Direct is a new technology that...
This paper investigates the robustness of the optimized link state routing (OLSR) protocol when used for unicast traffic in a highly dynamic military tactical scenario. The importance of the channel model in ad hoc network simulations is shown, as a radio channel model considering terrain effects and real radio transmission behaviour is employed. Results show, among other things, that using an advanced...
In past years, mobile ad hoc networks (MANETs) widespread use in many applications, including for some mission-critical applications, and has become one of the major concerns such as security MANETs. MANETs due to some unique characteristics, prevention methods are not alone enough to protect them need, Therefore, the detection is possible for an attacker to breach system security, such as the need...
Mobile ad-hoc network (MANET) is suffering from various attacks due to its infrastructure-less characteristics. Hence, MANET needs a variety of specific security methods to detect the false entrance of the misbehaving nodes. The network works well if the nodes are trusty and act rightly and cooperatively. In this paper, we are identifying and detecting the packet dropping nodes using the Support vector...
The proposed Heuristic clustered (HC) technique, can increase the performance of the mobile ad hoc network. This proposed Heuristic clustered (HC) technique can involve in three different stages such as clustering formation, software-based clustering, and heuristic clustered routing protocol. In clustering formation, cluster head will be selected based on the weighted clustering algorithm. Software-based...
Mobile ad hoc network (MANET) is a collection of wireless mobile nodes that dynamically form a temporary network without the reliance of any infrastructure or central administration. Energy consumption is considered as one of the major limitations in MANET, as the mobile nodes do not possess permanent power supply and have to rely on batteries, thus reducing network lifetime as batteries get exhausted...
This paper studies the fault management in mobile ad hoc networks. We focus on schemes which provide the robustness in MANETs: service restoration and service protection. Firstly, we propose an analytical comparison of service restoration, in terms of restoration time, at the routing layer (reactive and proactive protocols). Service restoration with reactive protocol is the most suitable in MANETs...
Nowadays, almost all telecommunication devices use TCP/IP to communicate with each other. However, it is difficult for MANET to support the type of end-to-end connectivity required by TCP/IP-based communications due to disruptions, frequent topology changes and network partitions caused by the movement of the nodes. DTN is an emerging paradigm in the telecommunication network which is able to provides...
Routing protocols have a significant impact on performance in mobile Ad hoc networks. In order to find the right routing protocols for “linear structure” of Ad hoc network, the principle of dynamic source routing (DSR) and Ad hoc on-demand distance vector routing (AODV) is studied, the same and differences of DSR and AODV is compared and analyzed. This paper analysis and comparison network performance...
Mobile Ad Hoc network works in hostile environment in absence of central control. Malicious or low energy nodes may degrade performance and also affects lifetime of the network. Broadcasting method which is commonly used for maintaining connectivity causes high overhead on the network. So it is necessary to exclude malicious and low energy nodes from the network and reduce the overhead. The proposed...
Utilization of mobile devices are burgeoning rapidly and consequently mobile ad-hoc networks (MANETs). The self configuring and infrastructure less property of MANETs makes them easily deployable anywhere and extremely dynamic in nature. Lack of centralized administration and coordinator are the reasons for MANET to be vulnerable to active attack like black hole. Black hole attack is ubiquitous in...
A Mobile Ad hoc Network is a self-organized network. The nodes which are within its radio range can have a direct communication if not it use an intermediate node for transmitting data. In MANET the nodes are wireless and fully distributed but they do not have any fixed infrastructure like base station or access points. MANET is a dynamic topology that is in this type of network the nodes will move...
An Integrated Internet MANET is a heterogeneous networking architecture which is formed by interconnecting wired Internet with wireless MANET. Such architecture is needed in order to realize the potential of, and to achieve the stated objectives of proposed 5G networks of the future. Several issues arise in Integrated Internet MANET, chief among them being Quality of Service (QoS). Packet type based...
In this paper we propose an extension to well known multipath reactive routing protocol Ad hoc On Demand Multipath Distance Vector (AOMDV). The resulting protocol is called as Hybrid on Demand Multipath Distance Vector (HOMDV). The proposed scheme improves AOMDV by using hello packets to learn neighbors up to two hops in addition to maintaining local connectivity. In this scheme a route requests is...
Multicasting in Mobile Ad hoc wireless Networks (MANETs) is a big challenge and a significant issue. Due to limited bandwidth and dynamic nature of ad hoc wireless networks, it is required that a multicast routing protocol should be efficient and effective. Existing tree-based and mesh-based multicast routing protocols are not suitable under multiple constraints. Ant Colony Optimization (ACO) is swarm...
the aim of this paper is to investigate the impacts of OPNET physical layer modelling on our proposed MANET routing protocol LANDY. And to assess how the data load impacts the routing protocol performance under two different physical layer environments, and two different mobility models (Gauss-Markov Model, and Reference Point Group Model). In this study, LANDY, DSR, GPSR, OLSR are used as the routing...
A mobile ad hoc network (MANET) is composed of multiple wireless mobile devices in which an infrastructure less network with dynamic topology is built based on wireless communication technologies. Novel applications such as location-based services and personal communication Apps used by mobile users with handheld wireless devices utilize MANET environments. In consequence, communication anonymity...
In today's world, there has been an enormous increase in mobile devices ranging from tablets, iPads, laptops and personal digital assistances (PDAs). These small gadgets which are usually battery powered enable communication to take place using radio waves. There is no infrastructure such as an access point or base station that has to be in place for communication to happen. This peer-to-peer wireless...
Mobile ad-hoc networks have to suffer with different types of packet dropping attacks. Therefore, we need strong mechanism to detect these malevolent nodes and to classify normal and abnormal nodes as per the behavior of nodes. Machine learning techniques distinguish outlier nodes quickly and accurately provide classification by observing behavior of those nodes in the network. In this paper, we study...
On-demand multipath routing in a mobile ad hoc network is effective in achieving load balancing over the network and more robust to mobility. In this paper, a node-disjoint multipath routing protocol is proposed, which forms opportunistic node-disjoint routes for data transmission and supports packet salvaging. The proposed scheme reduces routing overhead in forming multiple routes and achieves efficient...
