The multicast routing is very important for Mobile Ad hoc Networks (MANET). Though many multicast routing protocol are proposed, we consider ODMRP, which is a mesh based routing protocol. In ODMRP the reliability of the communication can be maintained by putting the relay nodes in the mesh. However, when the network is overloaded the performance of ODMRP is deteriorated. In this research, we try to...
Ad-hoc mobile networks consist of many mobile nodes which communicate by wireless connections without any fixed infrastructure. Our present article, we will compare two types of routing: the reactive algorithm (AODV) and the proactive algorithm (OLSR). Through our simulation carried out under NS2 (Network Simulator 2), we will show a classification of the various algorithms of routing studied according...
Mobile ad hoc network and peer-to-peer networks are most advancing and emerging research areas in the recent years. Both of these networks are based on the same phenomenon like self-configuration and self-organization. Although, peer-to-peer network was firstly designed for wired network but now a days it may be deployed over mobile ad hoc network. When P2P networks are deployed over ad hoc network,...
Wireless Sensor Network is an adhoc network having nodes with constraints like less memory and processing capability. Nodes work without knowledge of their position in the network. After random deployment of nodes, some of the nodes are in critical position as they connect one group of sensor nodes to another. If these nodes are removed from the network it may lead to partitioning of network. Most...
Ad hoc networks are composed of a set of mobile and wireless nodes. They have several characteristics such as being self-organized, dynamically changing topology and multi-hop connectivity. Ad-Hoc On-Demand Distance Vector Routing (AODV) is one of the most widely researched on-demand ad hoc routing protocols. An improvement of the route discovery process in AODV (IMAODV) is proposed to decrease the...
The wireless mesh network is a novel wireless network architecture that supports clients to communicate with different types of networks, Internet etc. It consists of mesh routers and mesh clients. These mesh routers are minimal mobile and mesh clients are totally mobile which operate on batteries. Hence, power consumption becomes an important issue in mesh clients. The protocols of Ad hoc networks...
A mobile ad hoc network has a dynamic topology. A route probably fails if intermediate nodes of the route have high mobility. In order to choose reliable nodes in a route, we define and quantify a novel routing metric called HBR that avoids choosing nodes with frequent failure history. Thus, route failure probability is decreased. We propose a routing scheme called HAODV based on the HBR metric. In...
The emergence of ubiquitous communication helps make safer and unobstructed street. Sensor detection is a valid technology to collect and process traffic data (vehicular speed, vehicle density, images from street) with the help of equipped sensors under the road or installed along the street. Vehicular sensor network (VSN), developed from wireless sensor network (WSN), is characterized by unlimited...
In this study the author carried out an experiment to transmit a datagram through mobile node using ad hoc routing technique directly without using smooth handoff when forwarding to MN fails with DSDV protocol. DSDV. In case of using routing protocol, it showed almost as same performance as when no handoff occurred, and the number of MN could increase transmission delay but had little relation with...
In recent years, various types of ad hoc routing protocols have been studied in the mobile ad hoc networks. Specifically, the clustering hierarchical routing algorithms have been developed to increase the system performance. Hierarchical structure has inevitably brought some drawbacks, maintaining the hierarchical structure needs more complicated cluster heads selection algorithm, which may result...
The ad hoc network is a non-infrastructure mobile network that consists of many mobile nodes. Since the nodes have a mobility features in ad hoc network, the ability of communication between the nodes is limited by nodespsila power. The power consumption and bandwidth of each mobile node becomes an important issue and needs to be addressed. The paper discusses the energy efficient routing problem...
This paper presents evaluation and comparison of the CBR performance in different mobile scenarios generated by Random Waypoint (RW) model. To our knowledge, CBR performance in RW mobility is discussed. The impact of AODV and DSDV routing protocols on the CBR delay and drop rate performance is also discussed. Extensive simulation results and analysis showed that CBR has better performance over AODV...
Most of the researcher worked on routing protocol in mobile ad hoc network but very less work has been done in data access. Caching in frequently accessed data in multi hop environment can improve the availability and performance of the network. However designing efficient distributed caching technique is not an easy task because of the movement of nodes. Connected dominating set is a frequently used...
An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any existing network infrastructure or centralized administration. The multipath routing in mobile ad hoc networks is difficult because the network topology may change constantly, and the available alternative path is inherently unreliable. A number of routing protocols like ad hoc...
Routing protocol is a key problem and critical to mobile wireless ad hoc networks. These instructions give you basic guidelines for preparing papers for conference proceedings. Routing, as an important part of ad hoc network, its performance has a vital effect on the system. In this paper, we discuss the all distributed routing algorithm and simulated this algorithm by using Matlab language. Layered...
Mobile adhoc network (MANET) is a network of a number of mobile routers and associated hosts, organized in a random fashion via wireless links. During recent years MANET has gained enormous amount of attention and has been widely used for not only military purposes but for search-and-rescue operations, intelligent transportation system, data collection, virtual classrooms and ubiquitous computing...
Vehicular ad hoc networks (VANET) are becoming an hot issue in these last years. These novel networks can offer the challenging vehicle-to-vehicle communication but a lot of issues need to be addressed on this topic. This paper focuses on the routing protocol issue in Manhattan environments. A novel protocol called two level trajectory based routing (TTBR) protocol is proposed. The deterministic vehicles...
