In the recent days, Mobile ad hoc networks (MANETs) are used extensively for applications that require mobility while routing, more importantly for emergency and military operations. Routing information to nodes without a fixed infrastructure and with dynamically changing infrastructure is one of the greatest challenges. Multicasting is a more frequent requirement for such defense operations, which...
As wireless nodes become more powerful, a large volume of diverse content, such as images or videos, become available in a mobile ad hoc network (MANET). It follows that a MANET can largely benefit from the support for "range queries", i.e., a query for content whose attributes are within a requested range. Supporting range queries over MANET is challenging due to node mobility and adverse...
Mobile Ad Hoc Networks (MANET) are a peer-to-peer communication network that can be used to transmit data using a mobile or wireless link without the support of fixed infrastructure. A literature survey highlighted that the key characteristics of efficient MANET nodes are reputation value, residual battery level and energy consumption. Various MANET algorithms and routing techniques such as location...
In wireless and distributed nature of Ad hoc networks, security has become a more sophisticated problem than security in other networks, due to the open nature and the lack of infrastructure of such networks. This paper is based on Blackhole attack. This attack node first needs to invade into the multicast forwarding group. It then absorbs all the data packets in the network and drops fully or partially...
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...
Delay tolerant networks (DTNs) are a special type of wireless mobile networks which may lack continuous network connectivity. Multicast is an important routing function that supports the distribution of data to a group of users, a service needed for many potential DTNs applications. While multicasting in the Internet and mobile ad hoc networks has been studied extensively, efficient multicasting in...
Geocasting is a routing method for ad hoc wireless networks that uses geographic information to multicast to nodes within the geocast region. The multicast members cannot receive multicast data continuously when they move outside the geocast region. Therefore, a geocast-based multicast method for continuous information delivery in MANET environments was developed. The method combines geocasting and...
The development of distributed application in mobile ad hoc network faces great challenges. Accordingly, it has important significance to introduce the content-based publish/subscribe middleware. First this paper defines subscription language and event model containing event type domain. Then it proposes a novel content-based routing protocol which establishes an optimized dynamic multicast mesh and...
In this paper, we introduce six-shot multicast (6Shot), a location-aware multicast algorithm devised for mobile ad hoc networks. Multicast is a one-to-many communication scheme and has largely been studied in such networks. Indeed, this communication primitive can be used as a building block for popular services, such as data streaming or group communication. The particularity of 6Shot is the location-...
The paper proposed a structure measure of multicast tree using FPN( fuzzy Petri net) model with the concept of IRS(immediately reachable set) in MANET(Mobile Ad Hoc Networks). It allows structured representation of network topology, and improves the efficiency of the ad hoc network routing scheme. Therefore when a packet is to be multicast to a group by a multicast source, a heuristic algorithm is...
In the past few years, the capacity of multicast traffic in large-scale random wireless networks has attracted considerable attention because of the fundamental importance of network capacity and the multicast applications. However, there are still significant gaps between the upper bounds and the constructive lower bounds. In this paper, we develop a novel percolation highway system with which the...
Most of the work on geocasting has been done for mobile ad-hoc networks and vehicular ad-hoc networks. This paper presents a novel Geocast technique with the hole detection in the geocast region for underwater environment. The proposed model named as Routing and Multicast Tree based Geocasting (RMTG) has been designed for underwater sensor networks. Here we propose a theoretical model for underwater...
Recently, the necessity of applications where many users have to interact in a close manner over mobile Ad-Hoc networks gains high popularity. Multicast communication is essential in this type of applications to reduce the overhead of group communication. For group-oriented multimedia applications Quality of Service (QoS) provision is a basic requirement, which makes an efficient QoS multicast routing...
Lifetime of multicast connection in a wireless ad-hoc network is constrained by routing topology as well as mobility, interference, noise and battery capacity. In order to optimize the multicast lifetime, a series of routing algorithms and cognitive network models with directional antennas have been proposed. However, these methods can only reach a sub-optimal level. In this paper, we propose an additional...
A mobile ad hoc network (MANET) is an autonomous network that consists of mobile nodes that communicate with each other over wireless links. An advent of new technologies and the demand for flexibility and ease in working environment, the use of Mobile Ad hoc computing is growing fast. Besides their use, Mobile Ad hoc networks (MANET) are assumed to grow in size too. They function in independent groups,...
Optimal broadcasting in mobile ad hoc networks is crucial for providing control and routing information for multicast and point to point communication algorithms. This paper presents static and dynamic cluster broadcasting for Mobile Ad Hoc Networks. The static cluster (cluster based source-independent CDS) consists fixed cluster heads and gateways. The dynamic cluster (cluster based source-dependent...
Delay/Disruption Tolerant Networks (DNTs) enables nodes to communicate by means of asynchronous sending messages without the need for an end-to-end path. In this paper, we study the problem of multicasting in DTNs. Several schemes have been proposed for multicast routing assuming the group of message receivers is known by sender, and the group members do not change during the process of message delivery...
In this position paper, we propose an agent based multicast routing scheme for mobile ad hoc networks (MANET) that builds a backbone in the form of reliable ring. The reliability of links is modeled by probabilistic measure of link failures to create reliable links and thus create multicast paths using reliable ring formed by these reliable links. The reliable ring is constructed by an agency that...
In this paper, we design a destination-driven on-demand multicast routing protocol for wireless ad hoc networks. The design objective is to improve the multicast forwarding efficiency. To achieve this goal, the path to reach a multicast destination is biased towards those paths passing through another multicast destination. If multiple such choices are available, the one leading to the least extra...
