The security is a key aspect in Mobile Ad-hoc Networks (MANETs), because the communication between the nodes is obtained using the wireless transmission, and the network setup is done without an infrastructure. In this scenario it is possible to perform internal and external attacks compromising the network functions. Moreover, the adoption of Intrusion Detection System (IDS) to discover internal...
Mobile Ad hoc network (MANET) is a set of two or more nodes that is used for wireless communication and networking capacity. These nodes are formed by the wireless hosts, without using pre-installed infrastructure and do not use centralized administration. Routing protocol define a set of rules which regulates the flow of data packets from source to destination. Distinctive features of MANET makes...
Devices in wireless networks, especially in ad hoc networks, are typically battery-powered. The need for energy efficiency in Mobile Ad Hoc Networks (MANETs) requires power enhancement features. Our work provides energy oriented power controlled mechanism to efficiently utilize the energy reserves and increase the network lifetime. The central idea is to select a Lead Node that will centrally manage...
In Mobile Ad hoc Networks (MANETs) nodes are free to move arbitrarily with different speeds, which makes the network topology change randomly and unpredictably. The mobility models give the movement pattern of the nodes w.r.t. their direction, location and speed over time. Some of these models depict real life scenarios. This paper analyses the energy consumption of our previous proposed energy efficient...
Mobile ad-hoc network (MANET) is an energy constraint multi-hop network and its nodes have routing capability with limited battery power. In such a network, establishing a correct and efficient route is a crucial design issue. But a more challenging goal is to provide an energy-efficient multi-hop route between source-destination pair. Thus, the routing protocols should setup an energy-efficient route...
Topology change is the main factor that affects the network life time of Wireless Sensor Network (WSN) applications. In static WSN, the topology change is often caused by node failure which is due to energy depletion. However, in the Mobile WSN (MWSN), the main reason of the topology change is caused by the node movement. Since the mobile sensor nodes are limited in power supply and have a low radio...
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...
Cognitive radio ad hoc networks (CRAHNs) are the ad hoc networks equipped with the intrinsic capabilities of the cognitive radio. As CRAHNs devices are mainly powered by battery, efficient consumption of energy is a key issue in CRAHNs. This paper focuses on energy-efficient routing in CRAHNs. It first compares CRAHNs with mobile ad hoc networks (MANETs), surveys the existing energy-efficient routing...
Energy efficient Routing is one of the key issues in MANETs due to their highly dynamic topology and limited battery power at the nodes. In particular identifying energy efficient routing is the most important design criterion in static and dynamic ad-hoc networks. Power failure of a mobile node not only affects the node itself but also reduces the overall network lifetime. The goal of this paper...
Mobile ad-hoc networks are one of the most active research areas in the wireless communications field. These networks do not need any fixed infrastructure or configuration, easily adapting to difficult scenarios and types of use. Since mobile nodes are often powered by limited batteries, energy is an important issue in MANETs since the lack of a node can lead to the partitioning of the network. Recently,...
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...
MANETs is mobile networks with no infrastructure. The main characteristic of MANETs is mobility, which causes dynamic changing of topology and link failure. Route repair mechanism, which is initiated after link failure occurred, broadcasts route request messages to the network to find a new route. Finally, there are only a few nodes selected to be the member of the new active route. That means most...
Nodes in Mobile Ad-hoc Networks (MANETs) are battery powered and hence have limited life time. Due to excessive utilization a node may die which can result in energy depletion problem and thereby affect overall network performance. Local rate of energy consumption based on application (e.g.: audio, video, word, etc) can be monitored. We can estimate the remaining battery life (residual energy in a...
A MANET comprises a set of mobile devices which are capable of communicating with others. Despite its flexibility and portability, it suffers from energy limitation. If the energy consumption of the nodes in the MANET cannot be balanced efficiently, some nodes will die in an early stage due to the energy depletion, which in turn partitions the whole network and leads to the communication failure....

First we analyze the shortcomings of existing routing protocols in intermittently connected mobile networks (ICMN) such as high delivery delay, low success rate and cannot adaptive to the different network environment. With this in mind, we propose a new routing scheme called adaptive multiple copy multiple hop algorithm (AMM). By collecting the simple information about the status of the network,...
Mobile Ad-Hoc Networks (MANETS) are characterized by random, multi-hop topologies that do not have a centralized coordinating entity or a fixed infrastructure that may change rapidly over time. In addition, mobile nodes operate with portable and finite power sources. In this work, we propose an energy-efficient metric for MANETs to minimize energy consumption and increase the networkpsilas consistency...
Dynamic Source Routing (DSR) Protocol is a commonly applied reactive protocol for mobile ad hoc networks (MANETs). When the network size is increased, overhead is increased due to the source routing nature of DSR. Moreover, energy consumption of the nodes increases, as the nodes act as intermediate nodes for many source destination pairs. In order to improve the scalability of DSR, in this paper,...
