AbstractHaving reliable telecommunication systems in the immediate aftermath of a catastrophic event makes a huge difference in the combined effort by local authorities, local fire and police departments, and rescue teams to save lives. This paper proposes a physical model that links base stations that are still operational with aerial platforms and then uses a machine learning framework to evolve ground-to-air propagation model for such an ad hoc network. Such a physical model is quick and easy to deploy and the underlying air-to-ground (ATG) propagation models are both resilient and scalable and may use a wide range of link budget, grade of service (GoS), and quality of service (QoS) parameters to optimise their performance and in turn the effectiveness of the physical model. The prediction results of a simulated deployment of such a physical model and the evolved propagation model in an ad hoc network offers much promise in restoring communication links during emergency relief operations.

Vehicular ad-hoc network (VANET), identified as a mobile ad hoc network MANETs with several added constraints. Basically, in VANETs, the network is established on the fly based on the availability of vehicles on roads and supporting infrastructures along the roads, such as base stations. Vehicles and road-side infrastructures are required to provide communication facilities, particularly when enough vehicles are not available on the roads for effective communication. VANETs are crucial for providing a wide range of safety and non-safety applications to road users. However, the specific fundamental problem in VANET is the challenge of creating effective communication between two fast-moving vehicles. Therefore, message routing is an issue for many safety and non-safety of VANETs applications. The challenge in designing a robust but reliable message dissemination technique is primarily due to the stringent QoS requirements of the VANETs safety applications. This paper investigated various methods and conducted literature on an idea to develop a model for efficient and reliable message dissemination routing techniques in VANET.

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.

In Mobile Ad hoc NETworks (MANETs) nodes communicate via wireless links, without any fixed infrastructure like base stations, central servers or mobile switching. Each node in MANET can act as a host or as a router. Due inherent characteristics like decentralization, self configuring, self -organizing networks, they can be deployed easily without need of expensive infrastructure and  have wide range of military to civilian and commercial applications. But wireless medium, dynamically changing topology, limited battery and lack of centralized control in MANETs, make them vulnerable to various types of attacks. This paper focus on network layer packet dropping attacks – Black Hole & Gray Hole attacks in Dynamic Source Routing (DSR) based MANETs and discuss various pros and cons of acknowledgement based techniques for detection of above said attacks.

Recently, mobile ad hoc networks (MANET) have gained an enormous popularity, which has led to an increasing need for the development of MANET applications. Developing MANET applications, however, is not an easy task. Developers have to deal with difficulties inherent from the wireless network environments. In this thesis, the design of a middleware that abstracts the functionalities of an unstructured overlay network is proposed. The main non-functional requirements that our design tries to achieve are portability, efficiency, and usability. Portability is achieved by following the J2ME platform specifications. The middleware has been implemented and tested on a real time ad hoc network using different platform devices. The performance measurements of the middleware show that it achieves its efficiency requirements. Furthermore, the middleware's usability is validated by showing how different applications can be designed and deployed easily on top of it. It provides a simple MBR-based file-search and path establishment mechanisms which we have proved to be the basis for implementing a wide range of applications, such as file sharing, ALM and gaming applications.

<p>Ad hoc network is specifically designed for the establishment of a network anywhere and anytime, which does not have any fixed infrastructure in order to support the mobility of the users in the network. The network is established without using any access points or base stations for communication implemented in multi hop schemes. Hence we call an Ad hoc network as a collection of nodes which are mobile in nature with a dynamic network infrastructure and forms a temporary network. Because of dynamic topological changes, these networks are vulnerable at the physical link, and they can easily be manipulated. An intruder can easily attack the Ad hoc network by loading the network resources which are available, such as wireless links and energy (battery) levels of other users, and then starts disturbing all the users. This paper provides a comparative survey on the various existing intrusion detection systems for Ad hoc networks based on the various approaches applied in the intrusion detection systems for providing security to the Ad hoc network.</p>

Required Quality

In the process of carrying out search and rescue operations and emergency response measures, organization of manpower and equipment management based on ensuring effective information exchange is of great importance. Moreover, tasks are often carried out in conditions of inoperative or absent telecommunication infrastructure and possible destructive external influences. In such situations, for the transfer of information, it is preferable to deploy a mobile ad hoc network, which has an arbitrary decentralized topology and is able to operate without base stations. In order to ensure the transmission of streaming data with the required quality in wireless packet-switched networks, various algorithms for the dynamic distribution and reservation of channel resources have been developed. However, insufficient attention has been paid to substantiating the duration of the transmission of streams of audio information in a mobile ad hoc network. The article presents the results of the development and research of an algorithm for obtaining the recommended duration of sessions for transmitting voice information streams to support decision-making to ensure the effectiveness of audio communications in a mobile ad hoc network. The recommended duration of the communication session depends on the limit number of packets in the audio stream, the calculation of which is based on the use of mathematical models to estimate the average volume of a multimedia message, the transmission of which can be carried out with the required quality for the given characteristics of the network. Implementation of the proposed algorithm will allow users of a mobile ad hoc network to receive messages about the recommended duration of audio communication sessions.

Only a small amount of work has been published on the topic of exploiting existing Long-Term Evolution-Advanced (LTE) cellular communication network infrastructure for Unmanned Aerial Vehicles (UAV) data links. This paper documents a modeling and simulation (m&s) framework that has been developed utilizing the powerful OMNeT[Formula: see text] simulation tool for assessing the feasibility and effectiveness of this prospect in various UAV scenarios. Using multiple scenarios, we have studied the data rate requirements for communications between small and medium-sized UAVs and base stations. Using this framework, we have shown that the data rate requirements for the links are within the data throughput achieved by LTE networks. The developed framework implements a propagation model endorsed by the 3GPP LTE project team and also accurately models the high mobility of UAVs. The framework is highly configurable and extensible and boasts of automatic aggregation of results and chart plotting. The outcomes of this research may be utilized by industry for rapidly deploying highly mobile, low-cost UAVs in a wide range of applications and scenarios.
