Mobile entities are unrestricted to form communication grid without any predefined substructure in MANET. Though it offers great resilience, but extra challenges for MANETs to guard against malevolent attacks are also fetched. Various tactics have been anticipated to discourse probable challenges to network operation, but they rely on unbending solutions, which are operative only in anticipated set-ups...
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...
This paper studies the problem of routing in a multilayer (communication and social) network. Network protocols, such as link state routing and its variants, heavily used in mobile ad hoc networks (MANETs) cannot sustain robustness and efficiency as the topological information becomes easily stale with fast network dynamics. Attempts to collect and exchange excessive network information would result...
In Ad-hoc networks, routing is complex as nodes are mobile due to which paths are destroyed and generated again and again. The difficulty in MANET is to find a feasible path between communicating nodes as routing is non-deterministic polynomial hard which is due to mobile nature of nodes. Many past works focused on finding a feasible path from a source to destination by considering only a single parameter...
Development of wireless network technology to support various types of information services continues to increase especially in video streaming services. Video transmission especially in Mobile Ad Hoc Network (MANET) environment used in this research, particularly in the Combined Scalable Video Coding (CSVC) scheme which is a development of H.264 / MPEG-4. The contribution of this research focuses...
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...
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...
In order to fit well into the heterogeneous MANET, various protocols have been proposed, and these protocols can be divided into two types, “flat” and “hierarchical” routing, according to their routing structure. Generally, “flat” routing protocols like OLSR, which can't distinguish the difference in performance among different interfaces and make best use of the higher capacity links, do not scale...
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...

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...
Security is the most important issue which needs to be given utmost importance and as both ‘Mobile Ad hoc Networks (MANET) and Wireless Sensor Networks (WSN) have similar system models, their security issues are also similar. This study deals in analysing the various lapses in security and the characteristics of various routing protocol's functionality and structure. This paper presents the implementation...
A node disseminates a message to all other nodes in the wireless adhoc network through broadcasting this is the basic requirement for broadcasting protocol. Clustering the nodes for broadcasting in mobile ad hoc networks plays a vital role in improving resource management and network performance (routing delay, bandwidth consumption and throughput). The clustered architecture of a mobile ad hoc network...
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...
MANET is a self-sorting out, decentralized, framework less, multi hop, remote system of cell phones. routing protocols assume a crucial part in transmission of information over the network. Streaming video is content sent in packed frame over the Internet and showed by the viewer continuously. Mobile Ad hoc Networks are considered for some applications. Routing protocols are the most imperative component...
Cluster computing in ad hoc network draws special attention from the research community due to its inherent support for group communication in varied application domains like emergency and rescue operations, etc. Context sensitive aware cluster computing yields maximum benefits and advantages than the traditional computing. The Cluster Head (CH) and the Cluster Members (CM) effectively coordinate...
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...
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...
