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 ...

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 ...

Detour attack in OLSR

Proceedings of the 4th international conference on Security of information and networks, 2011
In Optimized Link State Routing (OLSR), each node collects information about the network by exchanging control messages. The information is stored or updated in various repositories maintained at each node. The information in repositories is used to further generate control messages. A node has full control over its repositories.

Performance Analysis of DSR OLSR and OLSR-MIP in VANET

Advanced Materials Research, 2013
Vehicle Ad Hoc network (VANET) has grown fast in recent years. The routing protocol is one of the key technologies in VANET. Due to the particularity of VANET networks, the implementation and validation of all the protocols in realistic scenes are not possible.

Analysis of energy efficient OLSR extensions and OLSR-EXT energetic optimization proposal

Proceedings of the 10th ACM symposium on Performance evaluation of wireless ad hoc, sensor, & ubiquitous networks, 2013
Energy efficiency is a key issue for ad-hoc networks and several proposals have been explored in order to maximize network lifetime. This work analyzes the most relevant modifications proposed in the literature for OLSR in order to make it energy efficient and compares their performance results in terms of throughput, network lifetime and node energy ...

NC-OLSR: A network coding based OLSR multipath transmission scheme for FANETs

2017 4th International Conference on Systems and Informatics (ICSAI), 2017
Multipath routing has been proved to improve the reliability and throughput of data transmission in ad-hoc networks. However, in FANETs, due to frequent link failures and rapid changes in network topology, it is difficult to dynamically build these paths and the maintenance overhead is also unacceptable.

RESA-OLSR: RESources-aware OLSR-based routing mechanism for mobile ad-hoc networks

2016 International Conference on Military Communications and Information Systems (ICMCIS), 2016
This paper describes the performance enhancements of the routing mechanism for mobile ad-hoc networks. The presented solution is based on the proactive Optimized Link State Routing (OLSR) protocol. A new method was introduced to calculate the node performance metric with respect to the local resources, i.e., the battery level and the available ...
