The Internet uses hierarchical networking, for scalability and manageability reasons. However the main ad hoc routing solutions (OLSR [1], AODV [6], DSR [8], TBRPF [7]) only provide flat networking, and generally suffer important scalability issues. This paper therefore introduces a simple mechanism providing dynamic clustering with OLSR, one of the MANET routing solutions, chosen for its easy ...

An ad hoc network is a collection of wireless mobile nodes dynamically forming a temporary network without the use of any pre-existing network infrastructure. A number of ad hoc routing protocols have been developed during the time, but none of these is able to produce efficient routing of packets in large number of nodes due to their own limitations. Therefore, scalability is an open issue in ...

Optimized Link State Routing protocol (OLSR) is a promising routing protocol for multi-hop wireless ad-hoc networks, recently standardized by the IETF as a RFC. OLSR uses intensively the concept of Multi-Point Relays (MPR) to minimize the overhead of routing messages and limit the harmful effects of broadcasting in such networks. In this article, we are interested in the performance evaluations...

OLSR is a recent routing protocol for multi-hop wireless ad-hoc networks standardized by the IETF. It uses the concept of Multi-Point Relays (MPR) to minimize the overhead of routing messages and limit the harmful effects of broadcast in such networks. In this report, we are interested in the performance evaluation of Multi-Point Relays selection. We analyze the mean number of selected MPR in t...

OLSR (Optimized Link State Routing) protocol routing is a proactive routing protocol presented by the IETF MANET (Mobile Ad-hoc NETwork) working group for ad-hoc networks. The common drawback of all tabledriven protocols in MANETs is the large routing overhead for the creation of routing tables. In order to tackle this issue, OLSR uses the Multipoint Relaying protocol (MPR), which main use is t...

The routing is most quintessential issue in MANET networks. In MANETs the nodes are free to move, it has no fix structure and topology. In MANETs the routing policy is answerable for the performance of the network. In this paper, we deliberate the performance of latest routing protocol i.e. IFGRP in contrast with Tuned OLSR comparing the parameters load, delay and throughput. Tuned OLSR is the ...

Adhoc networks are part of IEEE 802.11 Wireless LAN Standard also called Independent Basic Service Set (IBSS) and work as Peer to Peer network by default. These work without the requirement of an Infrastructure (such as an Access Point) and demands specific routing requirements to work as a multihop network. There are various Adhoc network routing protocols which are categorized as Proactive, R...

A mobile Ad-hoc network consists of wireless nodes communicating without the need for a centralized administration. A user can move anytime in an ad hoc scenario and, as a result, such a network needs to have routing protocols which can adopt dynamically changing topology. To accomplish this, a number of ad hoc routing protocols have been proposed and implemented, which include DSR, OLSR and AO...

A MANET network is assembly of sensor nodes, where each node acts as router. MANETs are not based on centralized structure; therefore each node is responsible for routing the data packets from source to destination. This is done by implementing a routing protocol. Routing plays very influential role in MANETs. In this paper work an attempt has been made to compare the OLSR with GRP routing prot...
