Group mobility has become more evidently a phenomenon that will occur to MANET applications. This paper presents an extension to one of the current MANET WG standards, namely, OLSR for such scenarios. The extension LANMAR+OLSR seeks to provide OLSR the functionality of Landmark Routing, a scalable routing protocol designed for large-scale MANETs exhibiting group mobility. This paper describes t...

In this paper, we study multicast protocols for Mobile Ad-Hoc Networks, and specifically OLSR networks. We describe and compare three multicast protocols, namely MOST (Multicast Overlay Spanning Tree), MOLSR (Multicast OLSR) and SMOLSR (Simple Multicast OLSR), with different approaches and properties with respect to scalability. Our approach is simulation-based: through different scenarios and ...

Mobile Ad-hoc Network (MANET) are formed by a collection of mobile nodes, each equipped with wireless communication capabilities, without relying on any fixed infrastructure. In order to maintain network connectivity, each node may act as an ad hoc router, forwarding data packets for other mobile nodes that may not be within direct transmission range of each other. Energy efficiency is a most i...

Mobile Adhoc Networks (MANETs) are dynamic and self-organized temporary networks which include a set of mobile routers and hosts sharing same radio channel using wireless connections exchanging data without a centralized management. Due to limited transmission range of wireless Adhoc network nodes, multiple hops are usually needed for a node to exchange information with any other node in the ne...

We discuss and evaluate “Optimized Link State Routing Protocol” OLSR routing measurement performance analysis based on different simulation parameters. We have used NS-2 simulator tools for the performance of OLSR routing protocol simulation, we develop the simulation environment of small network (5, 10,15,25,30 Nodes) and observed the complexity of the mobile ad hoc network. The various perfor...

The optimised link state routing (OLSR) protocol is one of the most promising for mobile ad hoc networks (MANETs). Despite numerous proposals for quality of service in MANET, there is a lack of OLSR implementations that efficiently support applications with stringent QoS constraints like VoIP or videoconference. In this paper, we present a QoS-OLSR implementation based on a multiple-metric appr...

This paper aims to describe a novel QoS routing protocol for ad hoc networks based on the QOLSR protocol. The proposed QoS routing protocol is based on the standardized OLSR. The OLSR protocol is an optimization of the classical link state algorithm tailored to the requirements of a mobile wireless LAN networks. The standard OLSR introduces an interesting concept, the multipoint relays (MPRs), ...

This study aims at enhancing the Performance of Optimized Link State Protocol (OLSR) using Swarm Intelligence and Tabu Search Algorithm. It proposes OLSR modifications using Swarm Intelligence and Hybrid Particle Swarm Optimization (HPSO) by use of Tabu Search Algorithm (TSA). The OLSR Routing Protocol is used for the study of Mobile Ad hoc Networks (MANET) using Multimedia and Video Streamed T...

Wireless multi-hop networks consist of a collection of mobile and/or fixed nodes which dynamically exchange data with (or without) reliance on a (any) centralized administration. They are by definition self-organized. The frequent topological changes make multihop routing a crucial issue for these networks. To overcome these problems, new forms of routing schemes are used as the multipath routi...
