Packet data networks at sea offer the potential for increased safety, connectivity and meteorological data acquisition. Existing solutions including satellite communication are expensive and prohibitive to most small vessels. In this paper, an Internet of Things (IoT) application is proposed as a marine data acquisition and cartography system over Ship Ad-hoc Networks (SANET). Ships are proposed to...
A Mobile Ad-hoc Network (MANET) is a constantly self-configuring, infrastructure-less network of mobile devices where each device is wireless, moves without restraint and be a router to put across traffic unassociated to its own use. Every device must be prepared to constantly sustain the information obligatory for routing the traffic. And this is the main challenge in building a MANET. Such networks...
The Mobile Ad-hoc Network (MANET) is an infrastructure less network of mobile component without any prior structure of communication within the network. The primary major challenge is security and privacy while communicating mobile nodes in the network because of open environment of the MANET. MANETs are vulnerable to Packet Drop Attack is a type of Denial of Service (DoS) attack. Packet Drop Attack...
Networks are used in various fields. Network's popularity has motivated the development of mobile ad-hoc networks (MANETs). A mobile Ad-hoc network is a kind of decentralized wireless system which creates a fast changing network. Due to the dynamic nature and changing topology, MANET is a growing dynamic network, also called mobile mesh network. Mobile ad-hoc network has various kinds of security...
In mobile Ad-hoc networks, during the transmission of data, there is a chance of route failure, so that the route rediscovery should be done. Reactive routing protocol determines a route to a specific destination when a particular packet is going to send. Here we propose a reverse reactive routing protocol, based on new route discovery approach, which is used to find an optimal route to the destination...
In a public network, it is unlikely for a node which has limited resources to collaborate without gain. For avoidance of the fact that nodes refuse to cooperate in MANET, several schemes classified as reputation-based and credit-based, are considered suitable for ad-hoc networks, whereas many of these schemes are based on proactive or reactive routing protocols but none of them is based on a hybrid...
Supporting high mobility is essential to mobile ad hoc networks in a wide range of emerging applications such as vehicular networks. Communication links of an established communication path that extends between source and destination nodes are often broken under a high mobility environment. Although a new communication route can be established when a break in the communication path occurs, repeatedly...
Location-aided routing (LAR) is a mechanism which attempts to reduce the control message overhead of Ad-hoc on-demand distance vector (AODV) routing protocol by flooding only the portion of the network that is likely to contain the route to destination. LAR takes advantage of Global Positioning System (GPS) coordinates to identify a possible location of the destination node. Based on this information,...
Mobile devices in Mobile ad hoc network are battery operated. Battery energy is an important resource in MANET nodes. This energy affects the communication actions in network. There are a lot of methods have been suggested to conserve energy at different layer of the network models; many techniques are proposed by different study. To provide the power aware routing methods an models, one must need...
Mobile ad-hoc networks (MANETs) are autonomous distributed networks, where mobile nodes communicate with each other using wireless links. Since the communication is done by wireless links, it is difficult to grasp how the packets flow between communication nodes. It becomes even more difficult when the number of nodes is increased. In our previous work, we proposed a visualization system for MANET...
The routing performance in Mobile Ad-hoc Networks (MANETs) relies on the co-operation of the individual nodes that constitute the network. The existence of misbehaving nodes may paralyze the routing operation in MANETs. To overcome this behavior, the trustworthiness of the network nodes should be considered in the route selection process combined with the hop count. The trustworthiness is achieved...
Video transmission over ad hoc networks is more challenging than over other wireless networks. The wireless links in an ad hoc network are not very error resilient and can go down frequently because of node mobility, interference, channel fading, and the lack of infrastructure. Moreover, typical video applications may need a higher bandwidth and higher reliability connection than that provided by...
Group mobility is quite usual in many realistic mobile and wireless environments, but it is rarely adopted in multipath routing. We propose a Group mobility-based Multipath Routing protocol (GMR) for large and dense mobile ad-hoc networks (MANETs). The GMR protocol adapts intra-group routing and inter-group routing to handle group mobility. The routing table maintained by a group leader is used to...
Mobile ad-hoc networks (MANET) are particularly vulnerable on account of its intrinsic characteristics of open medium, dynamic topology, absence of central authorities, distributed cooperation and constrained capability. These vulnerabilities create significant challenges for routing protocols operating in the entire network. In which, the reactive routing, i.e. AODV, bears the brunt of various kinds...
Mobile ad-hoc networks are prone to a number of security threats. The fact that mobile ad-hoc networks lack fixed infrastructure and use wireless link for communication makes them very susceptible to an adversary's malicious attacks. Black hole attack is one of the severe security threats in ad-hoc networks which can be easily employed by exploiting vulnerability of on-demand routing protocols such...
Recent advances in networking technology have increased the potential for dynamic enterprise collaborations between an open set of entities on a global scale. Mobile ad-hoc networks (MANETs) have created problem in resource sharing as they are constructed via mobile nodes without any prior knowledge of the existing nodes which may not be trustworthy. Trust management appears to be a promising approach...
A new Virtual Base Station (VBS) election technique is proposed by this paper to help in QoS provisioning in the infrastructure-less Mobile Ad-hoc Networks referred to as MANET. This VBS election technique is based on the mobile node's Signal-to-Noise Ratio (SNR) and has been applied on the MANET's hybrid routing protocol: The Zone-based Routing Protocol. The developed routing protocol will be referred...
The absence of a router or a base station urges the need for a better access control mechanism in the ad-hoc networks. All the nodes in the network need to cooperate among themselves for proper functioning of the network. It is important to provide access only to the nodes, which cooperate in routing and forwarding, and to deny access to the selfish nodes. Selfish nodes send and receive their own...
Mobility is one of the most challenging issues in mobile ad-hoc networks which has a significant impact on performance of network protocols. To cope with this issue, the protocol designers should be able to analyze the movement of mobile nodes in a particular wireless network. In this paper, a new framework called mobility analyzer has been introduced for analysis and recognition of mobility traces...
This paper presents MPG (Mobile Process Group) protocol, a self-organizing and self-healing on-demand loop-free path routing protocol for mobile ad-hoc networks. The protocol uses the concept of mobile process groups to coordinate the mobile nodes and make communication amongst them reliable. The route discovery phase tries to discover a path from the source to the destination with the help of its...
