Link stability based enhancements to OLSR (LS-OLSR)

VTC-2005-Fall. 2005 IEEE 62nd Vehicular Technology Conference, 2005., 2006
The proliferation of Ad-Hoc network based applications have greatly increased the need for robust proactive routing protocol like Optimized Link State Routing (OLSR). OLSR uses Multipoint Relays (MPRs) for controlled flooding. The MPR selection process is defined as NP-complete set cover problem type.

LT-OLSR: Attack-tolerant OLSR against link spoofing

37th Annual IEEE Conference on Local Computer Networks, 2012
Optimized Link State Routing is a routing protocol that has been extensively studied for mobile ad-hoc networks. Link spoofing, which disturbs the routing service, is one of the critical security problems related to the OLSR protocol. Existing approaches against link spoofing attack have several drawbacks.

Hardware implementation of OLSR and improved OLSR (AOLSR) for AANETs

International Journal of Grid and Utility Computing, 2020
Airborne Ad-hoc Networks (AANETs) are a subclass of Vehicular Ad-hoc Networks (VANETs). The major challenge in AANET implementation is the regular route breaks due to very high mobility of aircraft...

Delay oriented OLSR

Proceedings. 2004 International Conference on Information and Communication Technologies: From Theory to Applications, 2004., 2004
We show the impact of using delay routing on network performances. We proposed an extension of the OLSR (optimized link state routing) protocol taking end-to-end delay as a metric. The critical part of this work is the estimation of the one hop delay by each node, based mainly on Hello control packets statistics and MAC 802.11 layer specification ...

SC-OLSR: Secure Clustering-Based OLSR Model for Ad Hoc Networks

2009 IEEE International Conference on Wireless and Mobile Computing, Networking and Communications, 2009
We consider the problem of prolonging the lifetime of ad hoc networks, using the OLSR routing protocol, in the presence of selfish nodes. This can be achieved by (1) reducing the number of relay nodes propagating the topology control messages and (2) considering the residual energy levels of these relay nodes.

EE-OLSR: Energy Efficient OLSR routing protocol for Mobile ad-hoc Networks

MILCOM 2008 - 2008 IEEE Military Communications Conference, 2008
This paper presents two novel mechanisms for the OLSR routing protocol, aiming to improve its energy performance in Mobile ah-hoc Networks. Routing protocols over MANET are an important issue and many proposals have been addressed to efficiently manage topology information, to offer network scalability and to prolong network lifetime.

CAC-OLSR: Extending OLSR to Provide Admission Control in Wireless Mesh Networks

International Journal of Wireless Information Networks, 2014
This work presents an admission control mechanism for multi-hop wireless mesh networks based on the IEEE 802.11 standard and the OLSR routing protocol. This mechanism, called CAC-OLSR, aims at ensuring that traffic flows with quality of service (QoS) requirements, especially voice and video, are only admitted in the mesh network if it has available ...

RBC-OLSR: Reputation-based clustering OLSR protocol for wireless ad hoc networks

Computer Communications, 2012
We consider the problem of assuring the trustworthiness (i.e. reliability and robustness) and prolonging the lifetime of wireless ad hoc networks, using the OLSR routing protocol, in the presence of selfish nodes. Assuring the trustworthiness of these networks can be achieved by selecting the most trusted paths, while prolonging the lifetime can be ...

Securing OLSR Routes

2005
Ad hoc networks offer novel capabilities in the mobile domain widening the mobile application field and arousing significant interest within mobile operators and industrials. Securing routing protocols for ad hoc networks appeared soon as a challenging scope for industrials and researchers’ community, since routing protocols, base of ad hoc networks ...

OLSR-H: A Satellite-Terrestrial Hybrid Broadcasting for OLSR Signaling

2011
Mobile ad hoc networks (MANETs) are proposed for emergency situations because they are self-organized and infrastructure-less. However, the mobility of the nodes and the lack of infrastructure pose challenges to the routing protocols. The signaling of these protocols is affected by the same problems as the data traffic: a multi-hop environment with ...
