A MANET or Mobile Ad-Hoc Network is decentralized in nature and it is basically a collection of heterogeneous mobile nodes which are autonomous and can communicate among themselves over the wireless link. In this infrastructure-less network, all the nodes dynamically route the packets by themselves with help of some protocols for sending or receiving the packet information. The ZRP or Zone Routing...
Mobile ad hoc Network (MANET) consists of autonomous mobile nodes without any centralized control. These mobile nodes move arbitrarily within the self-configurable MANET environment. Each of these mobile nodes can act as router while receiving and forwarding information. Secure routing is an important issue in MANET as mobile nodes are prone to attacks from malicious nodes and the overall performance...
Mobile Ad-Hoc Networks (MANETs) are collections of self-organizing mobile nodes with dynamic topologies and does not have any centralized control in the network. MANET have no clear way of defense mechanism to protect network from security threats, thereby making this network accessible to both legitimate node and authorized node. The absence of centralized administration and openness make MANETs...
Science of networking is still a relatively immature area. Proposing an efficient dynamic routing protocol for MANET is an arduous and provoking task. Various protocols for routing phenomenon have been proposed to IETF [1]. Considering an ad-hoc network which is specified by frequently changing topology and infrastructure less connectivity, a protocol must be tested under realistic conditions but...
Adhoc networking field has been interestingly accepted by the research society due to its surprising features. Almost every aspect of the network has been explored by the researchers at some level of detail. A lot of analyses/ surveys have been presented in the literature for showing the performance of well accepted adhoc routing protocols viz. AODV, DSR, AOMDV, CBRP etc. This paper presents some...
As per need of recent applications, new research aspects related to scalability, heterogeneity, and power consumption have been emerged. These issues are supposed to be fixed for better utilization of MANETs. MANET nodes interact through multi-hop routing. AODV is a commonly used on-demand protocol for routing in MANETs. In the existing literature, AODV has been analyzed a number of times but heterogeneity...
Mobile Ad Hoc NETworks (MANETs) have become eminent resources for providing communication to military and other defence establishments operating in the conventional battlefield scenario in enemy territory or Counter Insurgency/Counter Terrorism operations beyond the reach of a permanent network infrastructure. However, MANET's inherent topology lack in defensive procedures and are thus, vulnerable...
Ad hoc wireless networks are influence embarrassed because nodes function through restricted battery energy. Therefore, Energy expenditure is central propose of new ad hoc routing protocols. To propose such protocols we contain to give the impression of being missing from the conventional minimum hop routing schemes. Moreover, limited-energy property makes together nodes and network lifetime surrounded...
This paper proposes a new multipath protocol, Low Energy Consumption Stability and Energy Aware Reverse Ad hoc On-demand Distance Vector (LEC-SEAR-AODV) Routing Protocol. This is a modification of existing SEAR Ad hoc On-demand Distance Vector (SEAR-AODV) Routing Protocol. The LEC-SEAR-AODV uses the path with high RF value as the primary path to route the data packets whereas secondary paths are used...
We present in this paper a multi-layer scheme for QoS Management in MANETs. Our proposal is to combine multiple communication protocols of different layers, to provide an adapted QoS to a different traffic classes. Protocols are modified to improve their awareness of the quality of service, so that new extensions with QoS support are developed. We model QoS service at routing layer, via a QoS extension...
Wireless data transfer between mobile users has become more popular nowadays. In Mobile Ad-hoc Network, mobile nodes communicate with each other through the wireless medium, within the transmission range. If we use the data access applications in the wired network, the physical cabling in the wired network is restricting the connection topology and the bandwidth. But there is no such a restriction...
When some wireless networks are formed only for a particular purpose, they are the Mobile Ad-hoc Networks (MANETs). They do not depend on any access point for communication; they self-organize, and change topology dynamically. A routing protocol is necessary to help a node discover the routes to other nodes of the network and enable its communication with them. Each routing protocol tends to find...
In Ad hoc networks, there is no central infrastructure but it allows mobile devices to establish communication path. Since, there is no central infrastructure and mobile devices are moving randomly, gives rise to various kinds of problems, such as security and routing. Here the problem of routing will be considered. In this work, a new Route Selection Technique for AODV will be proposed that selects...
Mobile ad hoc networks (MANETs) are spontaneously deployed over a geographically limited area without well-established infrastructure. In a distributed Mobile Ad Hoc Network (MANET), collaboration and cooperation is critical concern to managing trust. The networks work well only if the mobile nodes are trusty and behave cooperatively. Due to the openness in network topology and absence of a centralized...
In Mobile Ad hoc Networks (MANETs), frequent link breakages occur which reduces the route lifetime and increases the frequency of invoking the route discovery process. Broadcasting is used in most of the reactive routing protocols for route discovery. Broadcasting increases routing overhead and end-to-end delay as well as decreases packet delivery ratio. To solve the broadcast storm and routing overhead...
Ad-hoc network, due to its fundamental characteristics like open environment operation, random topology and capability limitation, is mostly at risk from secuirity point of view. There may be malicious threats during data transmission from one user to another user, which leads to affect the system performance and causing insecurity in data transmission. Many routing protocols consider these secuirity...
Mobile Ad Hoc Networks (MANETs) are increasingly being used in various applications for civilian, commercial, and military uses. However, unique characteristics of MANETs introduce several challenges such as routing and mobility management. Nodes frequent movements make routing more difficult due to frequent topology changes. Dynamic Source Routing (DSR) routing protocol is among the common routing...
In mobile ad hoc network due to the limited transmission range of wireless nodes, multiple hops are needed to exchange information between nodes in the network. Thus routing is a crucial issue to design of a Mobile Ad-Hoc Network. So, there is need of efficient routing protocols to establish communication paths between nodes, without causing extreme control traffic overhead or power constrained devices...
The traditional Ad Hoc routing protocols do not scale well in heterogeneous networks, since they have not been designed to exploit different communication capabilities of network nodes. Building a heterogeneous hierarchical structure is a promising approach to achieve higher scalability in heterogeneous Ad Hoc networks. In this paper, we propose a novel heterogonous routing protocol based on DSDV,...
Congestion control in Mobile Ad-Hoc Network (MANET) is relatively different from that of traditional networks. The standard TCP congestion control approach is not adapted properly in the dynamic properties of MANET, which creates lot of challenges in routing, due to resources and bandwidth limits. In this paper, we proposed a self congestion prediction (SCP) algorithm for congestion prediction and...
