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 ...

An advanced signature system for OLSR

Proceedings of the 2nd ACM workshop on Security of ad hoc and sensor networks, 2004
In this paper we investigate security issues related to the Optimized Link State Routing Protocol -- one example of a proactive routing protocol for MANETs. We inventory the possible attacks against the integrity of the OLSR network routing infrastructure, and present a technique for securing the network.

An analysis of the lifetime of OLSR networks

Ad Hoc Networks, 2010
The Optimized Link State Routing (OLSR) protocol is a well-known route discovery protocol for ad-hoc networks. OLSR optimizes the flooding of link state information through the network using multipoint relays (MPRs). Only nodes selected as MPRs are responsible for forwarding control traffic.

Enhancing performance OLSR in MANET

2012 International Conference on Multimedia Computing and Systems, 2012
The performance of a Mobile Ad hoc Network (MANET) is closely related to the capability of the implemented routing protocol to adapt itself to unpredictable changes of topology network and link status. The Optimized Link State Routing (OLSR) protocol is a one key of the proactive routing protocols for MANETs. It is based on the multi-point relays (MPRs)

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 ...

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.

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.

OLSR Fuzzy Cost (OLSR-FC): an extension to OLSR protocol based on fuzzy logic and applied to prevent selfish nodes

open access: yes, 2014
This work contributes with an extension to the Optimized Link State Routing protocol (OLSR) called Fuzzy Cost OLSR (OLSR-FC). In order to prevent selfish nodes as well as to improve the traffic flow over Mobile Ad-hoc Networks (MANETs), the routing ...

An QoS Aware Link Defined OLSR (LD-OLSR) Routing Protocol for MANETS

Wireless Personal Communications, 2019
Mobile Adhoc Networks (MANETS) are gaining popularity because of interconnected networks. Routing is a key issue which needs to be addressed for efficient forwarding of packets from source to destination. Optimized Link State Routing (OLSR) is a proactive or table driven routing protocol in MANETS which works on the principal of link sensing.

Performance model of flooding in OLSR

Proceedings of the 7th ACM workshop on Performance evaluation of wireless ad hoc, sensor, and ubiquitous networks, 2010
OLSR is one of the most well developed routing protocols for MANETs. OLSR as a link state routing protocol relies on its flooding mechanism to disseminate topology information to all nodes in the network. However, the performance of the flooding algorithm is poorly understood.
