Analysis of the implicit trust within the OLSR protocol

چکیده
Trust is an interesting criterion for analyzing and comparing network protocols. The goal of this paper is to explicit the different types of trust relations between entities which exchange routing information and establish a routing infrastructure based on the OLSR protocol. One such entity assumes the other entities will behave in a particular way and the relations coming from this trust behavior are expressed in this paper using a formal language. This approach highlights the process of trust construction in OLSR and allows the analysis of trust requirements for this protocol, as well as the expression of attacks related to the betrayal of trust relations. Besides, this analysis allows the description of indicators for OLSR entities to have a protective mistrust behavior when effectively acting based on trust relations.

Trust-based security for the OLSR routing protocol
The trust is always present implicitly in the protocols based on cooperation, in particular, between the entities involved in routing operations in Ad hoc networks. Indeed, as the wireless range of such nodes is limited, the nodes mutually cooperate with their neighbors in order to extend the remote nodes and the entire network. In our work, we are interested by trust as security solution for O...
متن کاملComparative Performance Analysis of AODV,DSR, TORA and OLSR Routing Protocols in MANET Using OPNET
Mobile Ad Hoc Networks (MANETs) are receiving a significant interest and are becoming very popular in the world of wireless networks and telecommunication. MANETs consist of mobile nodes which can communicate with each other without any infrastructure or centralized administration. In MANETs, the movement of nodes is unpredictable and complex; thus making the routing of the packets challenging....

In mobile ad hoc networks, the absence ofinfrastructure and the consequent absence of authorizationfacilities impede the usual practice of establishing a practicalcriterion to distinguishing nodes as trusted and distrusted.Since all nodes in the MANETs would be used as router inmulti-hop applications, secure routing protocols have vital rulein the security of the network. So evaluating the perf...
متن کاملImproving Quality of Service Routing in Mobile Ad Hoc Networks Using OLSR
Mobile ad hoc networks (MANET) are constructed by mobile nodes without access point. Since MANET has certain constraints, including power shortages, an unstable wireless environment and node mobility, more power-efficient and reliable routing protocols are needed. The OLSR protocol is an optimization of the classical link state algorithm. OLSR introduces an interesting concept, the multipoint r...
