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...
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 this paper, we propose a novel scalable cluster based routing protocol for Mobile Ad hoc Network (MANET) named as Scalable Cluster Based Ad hoc On-demand Distance Vector (SCBAODV). This proposed SCBAODV is scalable, minimizes route failure, controls the Network Routing Load (NRL), end-to-end delay and improves the Packet Delivery Ratio (PDR). The network is divided into clusters and each cluster...
In this paper, we unified two new algorithms, i.e., to selectively Bordercast the control packets in order to reduce the network load by limiting the number of control packets when ZRP searches for a new route. The second algorithm is proposed to optimize the performance of Query control mechanisms for the Zone Routing Protocol (ZRP) for mobile ad hoc networks for communication on an urban terrain...
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...
Delay Tolerant Network (DTN) is evolved from Mobile Adhoc Network, MaNet. It is sparse and intermittently connected mobile adhoc network where reliable communication and end-to-end connectivity is not available for message transmission. The end to end connectivity is not ensured in Delay Tolerant Network. Only high latency applications are used in DTN. Latency may be in hours or days. The store and...
This paper outlines some important issues related to security attacks against mobile ad hoc networks. In designing security mechanisms for mobile ad hoc networks, one must consider the attacks variations as well as the characteristics of the attacks that could be launched against the ad hoc networks. The discussions of these two aspects are summarized in this paper. This paper also classifies several...
Due to the dynamic topology, limited and shared bandwidth of the mobile ad hoc network (MANET), providing Quality of Service (QoS) for MANET-based Networked Control Systems (NCS) is a challenging task. This paper integrates the concept of choosing stable route according to Received Signal Strength Indication (RSSI) into AQOR. Considering the data packet transmission characters of NCS, we let the intermediate...
MANET is a multi-hop, infrastructureless wireless network where nodes are free to move and have limited bandwidth and battery power. Energy is one of the important parameter for current research area. The aim of this paper is to develop an algorithm that will reduced the energy consumption and overhead of each node and improve the throughput. The algorithm called Energy based Gossip (EBG) routing...
The network topology in an ad hoc network is highly dynamic due to the movement of the nodes, hence mobility is a major constraint in designing routing protocols for them. Apart from mobility, the other major constraints are bandwidth and resource availability. In literature many routing protocols have been proposed for ad hoc networks. This paper focuses on designing a routing protocol for GPS enabled...
A mobile ad hoc network (MANET) consists of a collection of mobile nodes that communicate in a multi-hop way without a fixed infrastructure. Owing to its uniqueness such as easy deployment and self-organizing ability, it has shown great potential in many civil and military applications. As MANETs are gaining popularity, their need to support real time and multimedia applications is rising as well...
To truly realize potential of MANET, multimedia services must be provisioned with a minimum level of QoS. To meet the QoS requirement of such services, many attributes need to be considered. To keep the routing process lightweight, standard QoS aware routing protocol in MANET works with one or two such parameters. In this paper, we have proposed an on-demand source routing protocol for MANET that...
A mobile ad-hoc network (MANET) is a peer-to-peer wireless network where nodes can communicate with each other without the use of infrastructure such as access points or base stations. Nodes can join and leave the network at anytime and are free to move randomly and organize themselves arbitrarily. Due to this nature of MANET, it is possible that there could be some malicious and selfish nodes that...
The fast, efficient and reliable dynamic routing protocol is the basis to ensure highly reliable work of the mobile ad hoc network (MANET). For the shortcomings, the traditional proactive, reactive and hybrid routing protocol can not meet the requirements of reliable work of MANET. To address the problem and combined with the application requirements of small-scale MANET, a dynamic adjacent matrix...
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...
MANET (mobile ad hoc network) is a mobile multi-hop, wireless self-organized distributed network. This paper introduces the concept and characteristics of MANET, gives a general survey of research on local repair for MANET and proposes a new local repair scheme based on link breaks in order to make up the deficiency of the existing local repair schemes. The improved local repair scheme concerns about...
The stability and reliability of routing protocols in existence can not be well adapted to mobile ad hoc network, which is always shorted for MANET. In this paper, a novel routing algorithm is proposed and evaluated to reduce the overhead as well as to enhance the network stability for MANET. The thought of design came into being based on the way of ants foraging and work dividing. By making a selective...
Based on an autonomous algorithm, self-selection, the novel routing protocol called Self-selective routing (SSR) was proposed to support routing without the overhead of traditional ad hoc route maintenance. In this paper, we present a new routing protocol called self-selection based adaptive routing (SBAR), which is improved from the SSR protocol by using slot backoff delay time, adding expanding...
A fundamental issue arising in mobile ad hoc networks (MANETs) is the selection of the optimal path between any two nodes. A method that has been advocated to improve routing efficiency is to select the most stable path so as to reduce the latency and the overhead due to route reconstruction. In this work, we study both the availability and the duration probability of a routing path that is subject...
Routing is a challenging task in mobile adhoc network due to nodal mobility, unstable links and limited resources. Swarm intelligence, as demonstrated by biological swarm, such as ant colony has found to be a attractive technique for routing in MANET. However existing swarm intelligence based routing protocols find an optimal path by considering only one or two route selection metrics, such as hop...
