A Survey on MANETs: Architecture, Evolution, Applications, Security Issues and Solutions
Indonesian Journal of Electrical Engineering and Computer Science
Mobile ad hoc networks or MANETs, also referred to as mobile mesh networks at times, are self-configuring networks of mobile devices that are joined using wireless channels. These represent convoluted distributed systems comprising of wireless mobile nodes which are free to move and self-organise dynamically into temporary and arbitrary, ad hoc topologies. This makes it possible for devices as well as people to internetwork seamlessly in such regions that have no communication infrastructure in place. Conventionally, the single communication networking application following the ad hoc concept had been tactical networks. Lately, new technologies have been introduced such as IEEE 802.11, Hyperlan and Bluetooth that are assisting in the deployment of commercial MANETs external to the military realm. Such topical evolutions infuse a new and rising interest in MANET research and development. This paper provides an overview of the dynamic domain of MANETs. It begins with the discussion on...
One of new domains where the D2D communication can be applied is the Public Protection and Disaster Relief (PPDR) and National Security and Public Safety (NSPS) services. The key requirement for employing the PPDR and NSPS services is to provide the access to the communication services even if cellular network is highly overloaded or become fully dysfunctional due to some public disaster or emergency situations. In such case, the most important task is to share emergency information between citizens even when most of them do not have infrastructural connectivity. Since D2D is by default a single-hop communication, it is crucial to find the mechanism how to transmit any data via randomly assembled network even for longer distances. Therefore, this paper focuses on the utilization of MANET routing protocols for D2D communication in case that the connection to the cellular network is down. The selected routing protocols used in MANET are described and their suitability is verified in the simulation environment Network Simulator 3 (NS-3).
Mobile ad hoc networking: imperatives and challenges
Ad Hoc Networks, 2003
Mobile ad hoc networks (MANETs) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self-organize into arbitrary and temporary, “ad-hoc” network topologies, allowing people and devices to seamlessly internetwork in areas with no pre-existing communication infrastructure, e.g., disaster recovery environments. Ad hoc networking concept is not a new one, having been around in various forms for over 20 years. Traditionally, tactical networks have been the only communication networking application that followed the ad hoc paradigm. Recently, the introduction of new technologies such as the Bluetooth, IEEE 802.11 and Hyperlan are helping enable eventual commercial MANET deployments outside the military domain. These recent evolutions have been generating a renewed and growing interest in the research and development of MANET. This paper attempts to provide a comprehensive overview of this dynamic field. It first explains the important role that mobile ad hoc networks play in the evolution of future wireless technologies. Then, it reviews the latest research activities in these areas, including a summary of MANET’s characteristics, capabilities, applications, and design constraints. The paper concludes by presenting a set of challenges and problems requiring further research in the future.

Mobile Ad hoc Network is an ad hoc network that can be formed to allow nodes to communicate without any infrastructure. The set up of MANET makes it very popular as compared to the traditional wireless network. In traditional wireless network, mid-point is required for overall process of the network, whereas MANET is self-organized and infrastructure-free network, which is considered as a good approach for some specific applications such as battlefield survivability, communication in the natural or manmade disaster areas, emergency or rescue operations. This research work attempts to provide a wide overview of this active field and it first explains detailed survey of MANET in different fields and then takes over several challenges and issues in the Ad hoc networking area. Finally specify the active application areas of MANET and describes the future work.
IJERT-Behaviour and Analysis of MANET Routing Protocols for an Emergency and Rescue Scenario
International Journal of Engineering Research and Technology (IJERT), 2014

These characteristics of MANET make it suitable for an emergency and rescue scenario which requires effective communication. Routing strategies: proactive, reactive and hierarchical are considered, under which DSDV, DSR, AODV and CBRP are simulated and analysed for better performance in an emergency and rescue topography. NS2 simulator has been used for the study. From the comparative analysis of routing protocols it can be shown that the hierarchical routing strategy has a better performance in terms of parameters such as throughput, end to end delay, packet drop and packet delivery ratio for an emergency and rescue scenario.
