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.

DS-OLSR – Disaster Scenario Optimized Link State Routing Protocol

International Symposium on Communication Systems, Networks and Digital Signal Processing, 2020
The success of disaster recovery and rescue operations depends largely on effective communication between rescue teams (RT) and victims. Unfortunately, certain disasters go beyond crippling/impairing communication infrastructures as it equally cripples ...

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.

EIMO-ESOLSR: energy efficient and security-based model for OLSR routing protocol in mobile ad-hoc network

IET Communications, 2019
In numerous areas mobile ad hoc network (MANET) has plenteous mobile nodes that are allowed to communicate independently. In optimised link state routing protocols (OLSR), multi-point relays (MPR) are unique nodes that are chosen by different nodes to ...

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 ...

Bridge nodes based secure OLSR

Proceedings. 2005 International Conference on Wireless Communications, Networking and Mobile Computing, 2005., 2005
The existing secure routing protocols for ad hoc network are mainly based on bi-directional and symmetrical links, however, because of the special digital signals transmission equipments, which have different physical characteristic such as power range, there are many asymmetrical links in true wireless networks, so the successful authentication ratio ...
