A group of mobile nodes with limited capabilities sparsed in different clusters forms the backbone of Mobile Ad-Hoc Networks (MANET). In such situations, the requirements (mobility, performance, security, trust and timing constraints) vary with change in context, time, and geographic location of deployment. This leads to various performance and security challenges which necessitates a trade-off between...
In this paper, we investigate physical-layer security in a wireless ad hoc network in which a large number of legitimate transmitter-receiver pairs coexist with randomly distributed eavesdroppers; each legitimate receiver works in either half-duplex (HD) or full-duplex (FD) mode. We aim to increase the number of secure links per unit area in the network of interest by determining the allocation between...
For the mobile ad hoc networks (MANET) security is a vital element. For providing security against malicious nodes all the researchers are striving specially and particularly on all the security challenges in the MANETs. Within these wirelessnetworks some special techniques have been propounded for secure routing protocols. Our propounded work presents a more effective outcome to mitigate black hole...
A Local Area Network (LAN) consists of wireless mobile nodes that can communicate with each other through electromagneticradio waves. Mobile Ad hoc Network (MANET) consists of mobile nodes, the network is infrastructureless. It dynamically self-organizes in arbitrary and temporary network topologies. Security is extremely vital for MANET. Attacks pave way for security. Among all the potential attacks...
As the technologies overture, the communication media is upcoming with the need for wired and wireless networking. The wireless technology and portable computing devices enhances the future for wireless mobile networking. Mobile ad hoc network (MANET) is one of the emerging technologies with many applications. MANET is the network with specific characteristics like dynamic topology, wireless medium,...
The mobile ad hoc network and their concept is one of the most popular technologies now in these days. The wide range of applications are developed using this concept where the rapid development of network is required such disaster management and others. But according to the literature there are some issues are remain to fix such as security and performance. In this paper the security aspect of mobile...
Mobile ad hoc networks (MANETs) play a significant role for communication whenever infrastructure is not available. In MANET, the group communication-based applications use the multicast routing protocol, where there is a single sender node and a group of receiver nodes. The benefits of multicast routing protocols are the capability to reduce the communication costs and saving the network resources...
A mobile ad hoc network is a group of wireless mobile nodes with no infrastructure, in which individual mobile nodes are able to self organize and self configure in order to communicate within a direct wireless transmission range. However, the vulnerable nature of the mobile ad hoc networks (MANETs) makes them very prone to an adversary's malicious attacks such as dropping data or sending fake data...
Mobile ad hoc networks (MANET) is a type of networks that consists of autonomous nodes connecting directly without a top-down network architecture or central controller. Absence of base stations in MANET force the nodes to rely on their adjacent nodes in transmitting messages. The dynamic nature of MANET makes the relationship between nodes untrusted due to mobility of nodes. A malicious node may...
A Mobile Adhoc Network (MANET) is featured by multi hop wireless connectivity with topology change due to highly mobile stations with autonomous configuration ability. Therefore, it is very challenging to develop vibrant and resourceful routing Protocol for MANET which also performs excellent routig with security feasibility. This paper presents a detailed study and analysis of various routing issues...
Mobile ad hoc network (MANET) is one of the most important and unique network in wireless network which has brought maximum mobility and scalability. It is suitable for environments that need on fly setup. A lot of challenges come with implementing these networks. The most sensitive challenge that MANET faces is making the MANET energy efficient at the same time handling the security issues. In this...
Security is an essential requirement in mobile ad hoc network (MANETs). In this paper, we proposed the survey of countermeasures of all security attacks of network layer in MANETs. To the best of our knowledge, this is the first paper that explaining all the existing countermeasures of network layer attacks in MANETs. The countermeasures are features or functions that reduce or eliminate security...
A Mobile Ad hoc Network is a collection of mobile nodes forming network of their own. They have dynamic topology implying their mobility and no central authority implying their dual role as routers as well apart of transmitting and receiving the packets. It is implicit that they pave way for the malicious attacks leading havoc in the network. It is important to have secure transmission in order to...
A decentralized coded caching technique is introduced for wireless ad hoc networks in which all the existing contents are randomly combined and cached. The scaling behavior of the network is studied in terms of both capacity and security. Proactive and reactive routing techniques for coded caching are presented and the scaling capacity of the network for each case is derived. It has been shown that...
The dynamic distributed topology of a Mobile Ad Hoc Network (MANET) provides a number of challenges associated with decentralized infrastructure where each node can act as the source, destination and relay for traffic. MANET's are a suitable solution for distributed regional, military and emergency networks. MANETs do not utilize fixed infrastructure except where connectivity to carrier networks is...
Inside MANET, mobile devices can move independently devoid of pre established infrastructure. In this type of network there is no fixed topology for the network. To increase the coverage range and to obtain the global type of services these MANETs can be joined to other type of networks. For combination of heterogeneous type of networks, intermediate one which is a gateway is used to form a hybrid...
With the growing need of the time systems are becoming more and more sophisticated. Simple systems are changing drastically into more useful and complicated systems. Computer networks saw a major change from wired to wireless networks and quick wireless infrastructure became a new trend. Among many other wireless networks emerged MANET. Because of dynamic topology and no centralization, traditional...
Mobile hosts in a Mobile Ad-Hoc Network are linked by wireless links without usual routing infrastructure and link fixed routers. Ad-Hoc Distance vector Routing (AODV) is among one of the prominently used routing protocol for packet transfer from source to destination. It relies on maintaining most recent information, for which, each ad-hoc node maintains hop count and sequence number field. Ad-hoc...
Mobile ad hoc networks (MANETs) can be defined as a collection of large number of mobile nodes. Due to self configuring ability of nodes and infrastructure less nature of network, MANET is preferred in variety of applications such as military, disaster stuck areas, emergency recovery etc. MANET is vulnerable to various attacks due to its open medium and wide distribution of nodes. This itself emphasize...
Wireless Communication is an inevitable part of Smart Home domain. A Mobile Ad-Hoc Network (MANET) is defined as an arrangement of wireless mobile nodes which creates a temporary network for the communication. MANET suffers from both kinds of attacks, active and passive attacks at all the layers of the network model. The lacks of security measures of routing protocols allow attackers to intrude the...
