Impact of Node Mobility on MANET Routing Protocols Models

ثبت نشده
چکیده

A Mobile Ad-Hoc Network (MANET) is a self-configuring network of mobile nodes connected by wireless links to form an arbitrary topology without the use of existing infrastructure. In this paper, we have studied the effects of various mobility models on the performance of two routing protocols Dynamic Source Routing (DSR-Reactive Protocol) and Destination-Sequenced Distance-Vector (DSDV-Proactive Protocol). For experiment purposes, we have considered four mobility scenarios: Random Waypoint, Group Mobility, Freeway and Manhattan models. These four Mobility Models are selected to represent possibility of practical application in future. Performance comparison has also been conducted across varying node densities and number of hops. Experiment results illustrate that performance of the routing protocol varies across different mobility models, node densities and length of data paths.

Secure Routing Protocol: Affection on MANETs Performance

In mobile ad hoc networks, the absence ofinfrastructure and the consequent absence of authorizationfacilities impede the usual practice of establishing a practicalcriterion to distinguishing nodes as trusted and distrusted.Since all nodes in the MANETs would be used as router inmulti-hop applications, secure routing protocols have vital rulein the security of the network. So evaluating the perf...

Impact of Mobility Models with Different Scalability of Networks on MANET Routing Protocols

MANET routing protocols performance is perceptive to mobility and scalability of network. The performance of any routing protocol depends on the duration of interconnection among the nodes in the networks. This interconnections results an average connected path for whole network. This paper evaluates, the impact of three mobility models i.e. File mobility model , Random Waypoint and Group mobil...

Improving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR

Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...

On the Robustness of Simple Indoor MANET Simulation Models

We show that simple radio propagation and node mobility models widely used in MANET evaluation are not robust in indoor environments. Robust simulation models let researchers extrapolate simulation results and reach reliable conclusions about expected protocol performance. We experiment with two representative MANET routing protocols under different mobility and radio propagation models with de...

Impact of Mobility on Energy Consumption of AODV Protocol for Routing in Mobile Ad Hoc Networks

A Mobile Ad-hoc NETwork (MANET) is a collection of wireless mobile nodes forming a self-configuring network without using any established infrastructure. The nodes are battery operated and therefore energy is a scarce resource in MANET. Many routing algorithms are proposed in literature and evaluated under different scenarios. The Performance of MANETs not only depends upon the routing mechanis...

Impact of Radio Propagation Model and Mobility in On-demand Routing Protocol of Manet

Accuracy of routing protocol performance in mobile ad hoc network (MANET) depends on many parameters. Besides many parameters propagation model and node velocity are the two among them. Node mobility is responsible for network topology and propagation model for calculating signal strength at receiver. In wireless network MANET suffers a huge loss in performance due to obstacle between transmiss...
