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...
In VANETs and MANETs, the topology of the network changes very often, therefore implementation of efficient routing protocols is very important problem. In MANETs, the Random Waypoint (RW) model is used as a simulation model for generating node mobility pattern. On the other hand, in VANETs, the mobility patterns of nodes is restricted along the roads, and is affected by the movement of neighbour...
Mobile ad hoc networks (MANETs) can have widely varying characteristics under different deployments, and previous studies show that the characteristics impact the behavior of routing protocols for MANETs. To deploy applications successfully in MANETs, application developers need to comprehend the potential behavior of any underlying protocol used. In mobile networks, a major component of many of these...
The science of computer networking and the proliferation of mobile devices enable the capabilities of communicating with each other even in areas with no pre-existing communication infrastructure. Traffic and mobility models play an important role in evaluating the performance of these networks, despite criticism and assumption from various researches on TCP's weaknesses on MANET. A simulation was...
A new route repair scheme based on link breaks is proposed to improve route repair efficiency for realistic ad hoc networks. Its design idea is as follows. Change of downstream node status is regarded as the basis of choosing route repair schemes by the repairing node. Causes of link breaks would be analyzed according to the change of node status. And different nodes are selected as the destinations...
In Mobile Ad Hoc Networks (MANETs), routing is a challenging task due to node mobility, traffic and network size. It is very important to analyze the scalability characteristics of the routing protocols with respect to these parameters. Zone Routing Protocol (ZRP) is considered to be one of the most scalable routing protocols due to its multi-scoping and hybridization features. We propose a general,...
We present an analytical model combining geometric and stochastic approaches to describe the effects of attacks and countermeasures on MANETs. In particular, we focus on the packet loss that can be charged to the misbehavior as well as to the countermeasures as a primary metric. For this, we model the entire chain of (1) MANET routing, (2) attack, (3) intrusion detection, and (4) intrusion response...
In a mobile ad hoc network, where nodes are deployed without any wired infrastructure and communicate via multihop wireless links, the network topology is based on the nodes' locations and transmission ranges. The nodes communicate through wireless links, with each node acting as a relay when necessary to allow multihop communications. The network topology can have a major impact on network performance...
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...
