This paper is a survey of new and improved recent position based routing methods in Mobile Ad-hoc Networks. The referenced materials agree on the main challenge in creating energy efficient mobile ad-hoc networks. The quest is to realize a simple, yet efficient means of routing and managing the Mobile Ad-hoc Network communications with existing technology. Although many protocols have been proposed,...
A mobile ad hoc network (MANET) consists of a group of mobile nodes (MNs) that communicate with each other without the presence of infrastructure. The wireless mobile hosts communicate in a multihop fashion. In multi-hop wireless ad-hoc networks, designing energy-efficient routing protocols is critical since nodes have very limited energy, computing power and communication capabilities. For such protocols...
To support seamless communications for roaming users over heterogeneous wireless networks, mobile ad-hoc networks (MANETs) are receiving a special interest in the research community due to its infrastructure-less nature. MANETs can help to achieve a seamless service for users roaming over areas with no coverage from other wireless networks. As a result, MANETs are a key access network component of...
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...
Mobile Ad-Hoc Networks (MANETS) will play a significant role in future tactical military networks. Tactical networks are required to support military operations in areas without access to a fixed network infrastructure. They are also characterized by frequent changes in network topology due to node mobility and intermittent line-of-sight (LOS) connectivity. The self-forming and self-healing nature...
Mobile ad hoc network is wireless network of mobile nodes, with no centralized management and control. We proposed a protocol with an enhanced route discovery mechanism that avoids the congestion in the route. Our proposed protocol selects route on the basis of traffic load on the node and resets path as the topology changes. Instead of transmitting entire data through one route, new efficient paths...
A collection of mobile nodes in different speeds, transmission range random movement in absence of any static support of infrastructure is called a mobile adhoc network or MANET. In MANET, nodes have to announce their presence periodically and listen for their neighbors announcements broadcast to discover and learn how to reach each other. A new node is not familiar with its network topology at the...
Group mobility is quite usual in many realistic mobile and wireless environments, but it is rarely adopted in multipath routing. We propose a Group mobility-based Multipath Routing protocol (GMR) for large and dense mobile ad-hoc networks (MANETs). The GMR protocol adapts intra-group routing and inter-group routing to handle group mobility. The routing table maintained by a group leader is used to...
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-...
In mobile ad hoc networks, location service (LS) is critical and provides the fundamental service for geographic routing. However, most existing schemes for location service incur a high overhead because of the periodical updates of location information. In this paper, we intend to address this issue. Using the temporal relationship among historical locations of mobiles in the network, we propose...
Ad hoc networks are a new generation of networks offering unrestricted mobility without any underlying infrastructure. Due to lack of centralized control, secured communication in mobile ad hoc network is a crucial issue due to dynamic nature of the network topology. While the routing aspects of mobile ad hoc networks (MANETs) are already well understood, the research activities about security in...
The dynamic nature of MANETs makes the task of routing between source and destination nodes extremely difficult. In this paper a new efficient routing algorithm for mobile ad hoc networks is presented, along with a brief review of the state of the art scenario of routing topologies for MANETs. The new algorithm takes into consideration the mobility factor during routing. In the process, computational...
Data sharing is one of the most popular applications that dominate 70% of data traffic on the Internet. This application has been penetrating wireless mobile networks with dramatic speed, which allows the sharing of data whenever and wherever. However, traditional client-server data sharing model suffers from single point failure and low-scalable transmission in a highly dense and dynamic scenario...
The NEMO basic support protocol is a home agent based technique (derived from mobile IPv6) that permits the mobility of a network of IPv6 devices to be supported through the use of a dedicated mobile router. This NEMO mobile router accepts connections from IPv6 nodes and transparently manages any IP mobility on their behalf, which means that as well as individual hosts, a NEMO mobile router can also...
Clustering based routing protocols have the benefit of reducing routing overhead and increasing performance in the transmission delay and average throughput. In this paper, on the basis of CBRP we propose a new protocol called KHPCBRP (KHop passive clustering based routing protocol) which enlarges the range of electing clusterhead to K hops and adopts the strategy of passive clustering. In addition,...
Wireless Mesh Networks dynamically forms a network and each node connects and maintains a mesh network. The Mesh network is a hybrid WMNs, combined by two network mobilities which is the MANETs based Backbone WMNs and the non-MANET based Client WMNs. This research recommends a routing method that provides interoperability and effectiveness in the BWMNs and CWMNs combined HWMNs network. This method...
Providing secure routing in MANETs is far more difficult than in wired networks or static wireless networks. Node mobility and the relative scarcity of bandwidth render prior solutions ineffective. Solutions based on securing link or path information do not work well in MANETs because the dynamic nature of links requires extensive use of flooding. On the other hand, solutions based on hop-by-hop exchanges...
Mobile ad hoc networks (MANETs) are networks where the nodes are mobile, communicating via wireless link, operating without fixed infrastructure and each node act as a router (forwarding the in transit packets) as well as an end host. The movement of nodes is different in different scenario depending upon applications. Several routing protocols have been proposed by researchers for mobile ad hoc networks...
Mobile ad hoc networks (MANETs) have emerged as one of the most significant areas of research in the field of mobile computing. However, the mobility and disconnection of mobile hosts pose a number of problems in designing proper routing schemes for effective communication between any source and destination. In order to facilitate communication within the network, a routing protocol is used to discover...
The autonomous character of mobile ad-hoc networks (MANET) poses significant challenges on network communications. Some of the main challenges in this area related to routing protocols. To make MANETs adaptive to different mobility and traffic patterns, this paper proposes a novel routing scheme which is utilized cross layer design and attempts to develop DSR routing protocol in MANETs with simple...
