Routing decisions are often susceptible to failure in Mobile Ad hoc network (MANET) because of the special characteristics like dynamic topology and lack of central coordinator. Network topology changes very frequently due to the random movements of nodes and it is not predictable. The lack of central coordinator for controlling and managing the operations, often leads to very serious problems like...
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...
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...
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...
We propose the Floating Ground Architecture (FGA) for network mobility and ad hoc network convergence. Various factors, including excessive dependence on intelligence in the fixed network, result in the Internet having a de facto logical boundary one hop from the fixed network. To reduce these dependencies, FGA introduces a new logical layer, called Floating Ground, between the fixed network infrastructure...
Due to their intrinsic characteristics, Ad Hoc mobile networks could be subjects to disturbances or node break-downs. The latter are worsened by the nodes relay and mobility features. A more sophisticated Multihoming integration to MANET networks necessarily increases its robustness: in other words, it improves its performances. That is why we suggest in this article a new extension of the Stream...
Mobile ad-hoc network is networks that are collection of mobile device that can communicate and share information between each other, without any predefine infrastructure or centralized system. Another challenge in MANET is energy constraints because each of the mobile nodes is operated by limited energy battery. This paper presents a new on-demand power saving routing algorithm for mobile ad-hoc...
Security is the main issue of the mobile ad-hoc network, because of mobile nodes behavior. The topology of MANET changes frequently due to nodes mobility, by this property newly node easily enters or exit from a particular area. In this paper, we go through the study about mobile ad-hoc network and role of soft computing in this network. In our proposed work we apply Dempster Shafer theory for calculating...
In MANETs node's battery energy and stability of the links are often affecting the communication activities in network. These two factors are one of the main reasons which are responsible for the loss of data packets and occurrence of congestion issue that networks are facing toady. In order to overcome these issues we are proposing an approach known as Efficient and Stable Multipath Routing in MANETs...
Mobile Ad-hoc network (MANET), is one of the ideal means for communication using mobile devices, as the devices here can configure themselves without a strict interference by the network administrators. Providing apt security for such networks is a challenging task and this area has proved itself as a vital field for researchers. MANET s are more susceptible to network attacks because of their dynamic...
MANET's is exemplify at the time that the wireless networks in order that employ multihop wireless delivering along with are accomplished of performing beyond any settled infrastructure. So this type of infrastructure is called as framework less networks. The routing is an accurate chalking work in MANET's that the path is selected in network forward which sends the network service against origin...
Designing of Routing protocol is an important issue for a mobile ad-hoc network. Due to frequent changes in the topology of the network this becomes a major technical challenge. Node crash and link break in the network may cause losses of the networks resources. In signal strength based AODV protocol measures signals strength b/w node and evaluate with RSSI threshold values if it is larger than threshold...
One of the main considerations in designing routing protocols for Mobile Ad-Hoc Network (MANET) is to increase network lifetime by minimizing nodes' energy consumption, since nodes are typically battery powered. Many proposals have been addressed to this problem; however, few papers consider a proactive protocol like Optimized Link State Routing Protocol (OLSR) to better manage the energy consumption...
Wireless communication is used to establish connection between nodes that communicate with each other. MANET (Mobile ad hoc Network) is having Open nature that makes it vulnerable for various security threats. These vulnerabilities allow the attacker to compromise the network and degrade the performance of the network. Gray-hole attack is one of the dangerous attacks. A gray-hole attack is extremely...
A Mobile Ad hoc Network (MANET) is a dynamic wireless network without fixed infrastructure. Nodes move freely and organize themselves arbitrarily, and they usually have limited resources. Therefore, data delivery through this network requires cooperation among network nodes. Selfishness is a challenging problem that significantly degrades performance in MANETs. In this paper, we propose a selfishness...
Mobile ad-hoc network is a type of ad-hoc network where nodes change locations with time, configure themselves and get the information transmitted from source to destination without the help of any fixed router or base station. Hence, for efficient data transmission, it is critical to understand the type of routing algorithms that is being used by these networks. Since they have no fixed infrastructure...
As the technology gets advanced so as the security issues come into the picture. Here we will discuss about one such advancement in the modern world for communication purpose which is ruled by wireless networking. Precisely MANET (Mobile Adhoc Network) plays a huge role in transmission of data without any wired structure. Its distinct nature of maintaining the nodes and links to transmit the data...
The content centric network (CCN) is the new communication paradigm conceived for the future Internet. The basic idea of CCN is to use content names as addresses instead of IP-based host addresses. Video streaming services like YouTube represent the most important part of the internet traffic. Recently, the impact of mobility on video streaming over multi-hop wireless networks has become the real...
In military operation, sharing information among troops is essential issue for effective combats and minimal causalities. So these tendencies take militaries to information centric combat. And MANET has proper properties for this military operation such as infrastructure less, effective data transfer and flexible for changeable topology. Routing protocol is key factor of MANET. So to apply MANET into...
Mobile Ad-hoc is the most attractive area of research because of its dynamic topology and mobile environment of network. It is a structure less, self adjustable, dynamic network. Routing is the main challenging in MANET because of its nature. AODV is reactive routing protocol which is based on Breadth first search and it uses flooding. DSDV is a proactive routing protocol which maintains a routing...
