s A mobile ad hoc network is collection of self-configuring and adaption of wireless link between communicating devices (mobile devices) to form an arbitrary topology without the use of existing infrastructure. In wireless network technology, simulative analysis is a significant method to understand the performance of routing protocol. In this paper an attempt has been made to compare the perfo...

In this paper, we present path loss model for VANETs and simulate three routing protocols; Destination Sequenced Distance Vector (DSDV), Optimized Link State Routing (OLSR) and Dynamic MANET On-demand (DYMO) to evaluate and compare their performance using NS-2. The main contribution of this work is enhancement of existing techniques to achieve high efficiency of the underlying networks. After e...

In this paper, we have compared important characteristics of MANET proactive routing protocol (DSDV), reactive protocols (AODV, DSR and TORA) and hybrid protocol (ZRP). Extensive simulations are being carried out with different load conditions of MANETs. The offered network loads in the performance plots are characterized by three parameters i.e. packet size, number of connections i.e. source d...

A Mobile Ad hoc NETwork (MANET) is a kind of wireless ad-hoc network, and is a self configuring network of mobile routers (and associated hosts) connected by wireless links – the union of which forms an arbitrary topology. The routers are free to move randomly and organize themselves arbitrarily, thus the network's wireless topology may change rapidly and unpredictably. Such a network may opera...

In this paper, an effort was made to analyze the performance of Routing Protocols for Mobile Ad-hoc Networks. Wireless networks can be classified in two types: infrastructured wireless networks and infrastructureless (ad hoc) wireless networks. Ad hoc networks are characterized by the need for efficient routing protocols. According to previous research, the Destination-Sequenced Distance-Vector...

The analysis of traffic characteristics can be used for performance evaluation, design and implementation of routing protocols in WMNs (Wireless Mesh Networks). Higher bursty traffic will cause larger queue size, which means more dropping packets, and thus affects other metrics. Because burstiness can be modeled by multi-fractal characteristics effectively, multi-fractal characteristics of mobi...

One of the main research challenges in mobile ad hoc networks (MANETs) is designing adaptive, scalable and low-cost routing protocols for these highly dynamic environments. In this paper, we propose a new improvement on DSDV, which is one of the most popular proactive routing protocols in MANETs. We introduce a new metric called hop change metric in order to represent the changes in the network...

This paper aims to compare performance of some routing protocols for Mobile Ad-Hoc networks (MANETs). A Mobile Ad-Hoc Network (MANET) is a collection of wireless mobile nodes forming a temporary network without using any centralized access point, infrastructure, or centralized administration. Data transmission between two nodes in MANETs requires multiple hops as nodes transmission range is lim...

The Vehicular Adhoc network is the emerging research area which makes a phrase ‘Network on the wheel”. VANET is a collection of communication vehicles to broadcast desired information. In this paper performance of three routing protocols namely Adhoc On Demand Distance Vector Routing (AODV), Destination Sequence Distance Vector (DSDV) and VANET Radio Broadcasting Protocol (VANETRBC) is compared...
