This article presents simulation results for a mobile ad-hoc network running Dynamic Source Routing reactive protocol under the conditions of limited availability and heightened response times of network nodes. Authors conclude that dynamic source routing stops being efficient in large networks and propose a hybrid routing protocol that includes the proactive phase and uses availability criterion...
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...
In this paper the performance analysis of a routing algorithm for MANETs called Service Zone Gateway Prediction (SZGP) is presented. This is a non-cooperative and hybrid type of routing with a hierarchical multilayered structure, incorporating pre-computed multipath hop-by-hop distributed connectivity. The goal is balance of the load among the nodes and reliable and energy efficient communication...
Indeed, MANET's are an emerging technology, evolved to provide users with facility to establish Ad-hoc networks for seamless communication. Routing is a major issue in MANET's. AODV is considered as one of most efficient routing protocol in MANET's but, its performance is adversely effected by various security attacks. A routing protocol can be attacked in many ways so as to disrupt the routing process...
Secure routing in the field of mobile ad hoc network (MANET) is one of the most flourishing areas of research. Devising a trustworthy security protocol for ad hoc routing is a challenging task due to the unique network characteristics such as lack of central authority, rapid node mobility, frequent topology changes, insecure operational environment, and confined availability of resources. Due to low...
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...
Mobile Ad hoc Networks (MANETs) are self-configuring, de-centralized and a kind of multi hop wireless packet networks, where the mobile gadgets (also referred to as nodes) communicate with each other on wireless links. Such networks find applications where a quick deployment or dynamic reconfiguration of network is required, or there is no pre-existing network infrastructure or wired network is available...
MANETs is collection of wireless network establishing a network in which nodes communicate with each other by network systems such as the Internet. MANETs routing protocols are characterized into two types, for example, table-driven and on-request or demand. In this network node performed as a function of routers which discovers and maintain the path to other node. In Adhoc network nodes are easily...
Mobile ad hoc Network (MANET) consists of autonomous mobile nodes without any centralized control. These mobile nodes move arbitrarily within the self-configurable MANET environment. Each of these mobile nodes can act as router while receiving and forwarding information. Secure routing is an important issue in MANET as mobile nodes are prone to attacks from malicious nodes and the overall performance...
As the practical propagation environment suffers from various fading, investigation of a suitable routing protocol for this type of environment is need of the day. Many routing protocols have been evaluated for idle conditions but none of them have taken actual physical environments such as fading, etc. into consideration. In this paper, that particular Issue has been addressed. Three most popularly...
Many MANET routing protocols do not perform well in dense scenarios with high network load. In these situations, we can observe a high level of route instability, which is often called "route flapping". In this paper we present the PRIME routing protocol, which uses a probabilistic multipath forwarding process to increase route stability in dense scenarios with high network load. We describe...
SatSim was developed to provide a low cost, easy to learn, network simulator for simulating satellite networks. SatSim is unique in that it accurately accounts for orbital movement of satellites on a discrete per packet basis that heavily affects communication link quality. SatSim can be seen as a special case of a typical network simulator, developed for networks that require physical node movement...
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...
Multicasting plays an important role in the typical application of ad hoc wireless networks namely, emergency search and rescue operations, military applications etc. Implementing multicast routing protocols to MANETs leads to improve the consumption of bandwidth, improving the efficiency and reducing the cost of communication in the network. A tree based multicast routing protocol i.e. Multicast...
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...
For making Mobile ad hoc network (MANET) more energy efficient swarm intelligence is used as a base and the clustered based approach as Bee-Ad Hoc-C which is an evolution from Bee-Ad-Hoc has been chosen as the best method in our previous work along with Stable Cluster Maintenance Scheme. In the proposed method parallel routing has been considered to improve the scalability of the system, reduce the...
