MANETs are unplanned, self-organizing networks composed of mobile nodes that utilize mesh networking principles for inter-connectivity. They do not have a fixed infra-structure which makes them easy to build over an area. Mobile Ad hoc networks (MANETs) have several advantages compared to traditional wireless networks. These include ease of deployment, speed of deployment and decreased dependency...
Mobile Ad hoc network consists of a collection of mobile nodes capable of forming instantaneous network with dynamic topology. Each node simultaneously acts as both router and host. Nodes can leave or join the network freely. Destination Sequence Distance Vector (DSDV) is a modification of the conventional Bellman-Ford routing algorithm for ad hoc networks. Dynamic topology of ad hoc networks makes...
Energy efficient topology in Ad-hoc networks can be achieved mainly in two different ways. In the first method, network maintains a small number of nodes to form a connected backbone and the remaining nodes sleep to conserve energy. This method is effective for low traffic networks. Energy efficiency in the second method is achieved by power control technique. This technique is effective in high traffic...
In recent year with the widespread use of mobile device, Mobile Ad hoc networks (MANETs) technology has been attracted attention day by day. Due to MANETs don't need the infrastructure, it can deploy fast and conveniently in any environment. Because of its easy deployment features, in addition to used in personal area networks, home area networks and so on. Specially, MANETs suit for military operations...
Without any pre-existing fixed network infrastructure with rapid configuration of wireless connections on-the-fly, network topology in MANETs keep on changing rapidly. Thus achieving data transmissions between wireless nodes in MANETs with improved QoS parameters become a challenging issue. To achieve this one has to concentrate on the routing protocol they choose. In our paper we proposed an algorithm...
Mobile Ad Hoc Network (MANET) consists of a collection of wireless mobile hosts without the required intervention of any existing infrastructure or centralized access point such as base station. The dynamic topology of MANET allows nodes to join and leave the network at any point of time. Wireless MANET is particularly vulnerable due to its fundamental characteristics such as open medium, dynamic...
The key nodes in network play the critical role in system recovery and survival. Many traditional key nodes selection algorithms utilize the characters of the physical topology to find the key nodes. But they can hardly succeed in the mobile ad hoc network due to the mobility nature of the network. In this paper we propose a social-aware Kcore selection algorithm to work in the Pocket Switched Network...
In recent years group-oriented services are one of the primary application classes that are addressed by Mobile Ad hoc Networks (MANET). To support such services, multicast routing is used. Multicast routing is the simultaneous delivery of data stream to multiple destinations without sending duplicate copies over any one link with the objective of resource optimization. It can significantly improve...
DYMO as a routing protocol is newly intended for use by mobile nodes in wireless multihop network. It offers adaptation to changing network topology and determines unicast routes between nodes within the network on-demand. It is designed for MANET (Mobile Ad hoc Network) in small, medium, and large node populations. It handles all mobility ranges and various traffic patterns. It is simulated using...
Recent years, the mobile ad hoc networks (MANETs) research community has been very active. Thus, it is of growing importance to build distributed network applications on top of MANETs. DHT is known as a popular technique to build efficient distributed applications in the Internet. However, in MANETs, DHT needs to consider network traffics, moving of nodes and energy efficiency more carefully than...
A major aspect of mobile ad hoc network (MANET) is that the nodes move randomly, which requires the routing protocols in ad-hoc network to quickly respond to the network topology change in order to guarantee successful data packet delivery. MAODV (multicast ad hoc on-demand distance vector) routing protocol provides fast and efficient route establishment between mobile nodes that need to communicate...
Mobile ad hoc networks are increasingly finding their existence in the marketplace heading to a new paradigm of pervasive computing. However there are many areas open to research in the field. Due to node mobility resulting in an ever-changing network topology, conventional routing methods cannot be applied in MANETS. Therefore, this is one of the core areas of research. Researchers are challenged...
This paper presents the state of the art in biologically inspired ant based routing in wireless mobile ad hoc networks (MANET). The motivation for using ant-like mobile agents for providing routing information to mobile hosts in MANETs stems from the fact that ant-like mobile agents do not require high bandwidth overhead compared to MANET proactive routing protocols for disseminating the topology...
Mobile ad hoc networks (MANET) are modeled as agents that form communities without infrastructure, for a random period of time and with usually cooperative behavior. The nodes of MANET often carry information to disseminate. The dynamics of information delivery, mostly referred as average consensus, is a common problem in these networks. The gossip protocols are designed to implement this task. The...
In this paper we have presented a physical implementation of a topology control algorithm for MANETs. Mobile nodes follow the characteristics of the nomadic community mobility model. The proposed algorithm maintains the topology without any control message. There is no need to change routing table as connectivity of the network is maintained all through. Every node in the network is free to travel...
Mobile ad hoc networks (MANETs) are receiving more and more attention for the extensive field of applications. However, due to the topology dynamic and limitations on resources, the discovery of services is a challenging issue in MANETs. Without considering the different utilization rates of discovered services during executing, existing solutions mostly focus on a maximized service discovery rate,...
Due to the insecure nature of the wireless media, the dynamically changing topology and lack of infrastructure, security in mobile ad hoc networks is hard to achieve. In this paper we present an analysis of a message-relaying based key distribution scheme for mobile ad hoc networks that was previously proposed by van der Merwe et al. Considering the message overhead occurring at the MAC layer in addition...
