Nowadays, the location awareness becomes a ubiquitous requirement for several computing applications. The utilization of such knowledge in mobile ad hoc networks is primarily limited by the scarcity of their resources. In this paper, we propose two cartography gathering schemes (OLSR-SCGS and OLSR-ACGS) that make use of the seminal OLSR signaling in order to endue nodes participating in the MAN...

Multipath routing protocols for Mobile Ad hoc NETwork (MANET) address the problem of scalability, security (confidentiality and integrity), lifetime of networks, instability of wireless transmissions, and their adaptation to applications. Our protocol, called MP-OLSR (MultiPath OLSR), is a multipath routing protocol based on OLSR [1]. The Multipath Dijkstra Algorithm is proposed to obtain multi...

The MANET networks are of prime interest for military networks. One of the proeminent routing protocols for MANET is OLSR, and indeed, OLSR has been used in many evaluations and experiments of MANETs. As OLSR is on its way to standardization, there are still a number of extensions that are useful and sometimes necessary for practical use of OLSR networks: such extensions are quality of service ...

Localization protocol is important for estimating node positions in a wireless multi-hop network. Routing protocol is also important for controlling paths. In previous research, localization and routing protocols have been discussed and evaluated separately. In this paper, we propose an integrated protocol for optimized link state routing (OLSR) and OLSR based localization (ROULA). Our protocol...

In this paper analysis and performance of OLSR and TORA routing protocols is done. We used OPNET Simulation tool we created a network containing 50 mobile nodes with data rate 1 Mbps and 2 Mbps with transmission power 0.005 watts and buffer size 256000 bits each node moves randomly in the network and simulation time was 1500 sec. TORA and OLSR routing protocols were compared in terms of Traffic...

Optimized Link State Routing (OLSR) protocol is a leading proactive routing protocol for Mobile Ad-hoc Networks (MANETs). Since the OLSR protocol in its standard version does not support multi-path packet forwarding, we have developed and implemented its multi-path extension. As a result of a slightly modified path computation algorithm and the application of backpressure Max-Weight Scheduling ...

In link state routing networks, every node has to construct a topological map through the generation and exchange of routing information. Nevertheless, if a node misbehaves then the connectivity in the network is compromised. The proactive Optimized Link State Routing (OLSR) protocol has been designed exclusively for Mobile Ad Hoc Networks (MANETs). The core of the protocol is the selection of ...

In the future combat networks, the Optimized Link State Routing (OLSR) protocol is one of the proactive routing protocol considered to guarantee reliable data communication. However, the conventional OLSR and enhanced OLSR as OLSRv2 does not efficiently consider reducing control message overhead and route recovery delay in multi-interface multi-channel (MIMC) based cognitive radio environments....

This paper provides a measurement-based performance evaluation of the Optimized Link State Routing (OLSR) protocol. Two versions of OLSR, OLSR-ETX and OLSR-ETT, are implemented and evaluated on a mesh network that we built from off-the-shelf commercial components and deployed within our department building. OLSR-ETX uses the Expected Transmission Count (ETX) metric, whereas OLSR-ETT uses the Ex...
