The recent spread of mobile networks has paved the way for building a pervasive social networking (PSN) environment, which enables people to access social networking services (SNS) anytime and from anywhere. There have been extensive studies on MANETs (Mobile Ad-hoc NETworks), which use mobile terminals for relaying information. While the feasibility of using them as emergency networks in the aftermath...
Wireless networks can be categorized into infrastructure and infrastructure-less based on the network formation and architecture. Mobile Ad-hoc Networks are infrastructure-less networks with self-configuring property having a dynamic topology where nodes are free to move in any direction, due to this topological changes there are increased chances of link breaks in the network giving rise to path...
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 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...
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...

As MANET is an infrastructure less, problems related to reduce Flooding by Propagating Neighborhood Information Algorithm (PNIA) is instant path transformation with reverence to transform in topology and blocking in the network. In this paper we have explained on PNIA with Grid Fisheye State Routing Protocol for MANET and implemented with various metrics in NS3 Simulator. Also the proposed work is...
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...
MANETs are an upcoming technology that is gaining momentum in recent years. Due to their unique characteristics, MANETs are suffering from wide range of security attacks. Wormhole is a common security issue encounter in MANETs routing protocol. A new routing protocol naming extended prime product number (EPPN) based on the hop count model is proposed in this article. Here hop count between source...
While mobile ad hoc networks have become a mature & globally adopted technology due to its wide range of applications. Such environment has some basic differences in comparison to wired networks. Due to these little differences the MANETs are more prone to interception and manipulation. This further opens possibilities of insecure routing. For the efficient and secure delivery of data CRCMD&R...
An opportunistic network (OPPNET) is an alternative to a mobile ad-hoc network (MANET) in which no complete path is needed. If a complete path is unavailable, the source node sends the message through relay nodes until the message arrives at its destination. Friendship-Based Routing (FBR) is routing scheme for an OPPNET which uses the inter-contact time of each node to find a good relay node. Unfortunately,...
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...
The main objective of this paper is to improve the performance of MANETs with high immunity towards network attacks Grey Hole Attackers and Black Hole Attackers. In the clustered network if the elected cluster node [2] itself becomes a malicious node or selfish node, then the performance of data communication reduces. Hence the security of cluster head is necessary. Here nodes are selected conceding...
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...
This paper presents the study of the Hierarchical Distance-Vector Geo-Routing (HDVG) protocol for Mobile Ad-Hoc Networks (MANETs) using NS-3 simulator. The criteria for selection of simulation environment are described. The distributed computing technique for NS-3 simulator is proposed. Simulation results show that HDVG, in general case, outperforms well-known routing protocols OLSR, AODV and GPRS.
In Mobile Ad hoc Networks (MANETs), with Optimized Link State Routing Protocol (OLSR) the mobility concept is an essential element which can result in the evolution of network performances. In this paper, the main objective is to develop an algorithm to improve the MultiPoint Relay (MPR) selection process in such networks. This algorithm is based on the Mobility Rate (MR) which in turn is relied on...
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...
Communication is no longer restricted to areas with telecommunication network infrastructure due to the introduction of wireless mobile Ad-hoc Network (MANET) that makes it possible to communicate anytime anywhere, without the support of a pre-existing network infrastructure. Unfortunately, MANET comes with unique features which are neither common to the conventional wired networks nor the cellular...
A mobile adhoc network is an independent system of mobile stations associated by wireless link to form a system. This system can be modeled in the form of an uninformed graph. Adhoc networks are peer to peer, multihope networks were data packets are transmitted to a source to destination through intermediate nodes (which serve as router). The infrastructure is not the main issue to setup MANET and...
