OLSR-R^3: Optimised link state routing with reactive route recovery
نویسندگان
چکیده
The Optimised Link State Routing (OLSR) is a proactive routing protocol which relies on periodical broadcast of routing packets. However, due to the one-to-many relationship of broadcast traffic, the delivery of these packets can not be guaranteed by underlying MAC protocol, particularly in a congested condition. In this paper, the possible routing pathologies and failures of OLSR in a congested network are explored. In addition, a hybrid routing protocol which integrates OLSR with Reactive Route Recovery (OLSR-R3) is proposed to rectify the erratic routing behaviour described in this paper. Simulation studies are presented which show that the proposed solution is effective in addressing the underlining problems.

A Cross-layer Enhancement of Geographical OLSR for MIMC-based Tactical Ad Hoc Networks
In the future combat networks, the Optimized Link State Routing (OLSR) protocol is one of the proactive routing protocol considered to guarantee reliable data communication. However, the conventional OLSR and enhanced OLSR as OLSRv2 does not efficiently consider reducing control message overhead and route recovery delay in multi-interface multi-channel (MIMC) based cognitive radio environments....

Self-organizing ad hoc networks need development of efficient routing protocols in terms of reliable routing and energy conservation. For dense ad hoc networks, Optimized Link State Routing (OLSR) protocol is suitable due to its multipoint relaying (MPR) feature. We have tried to make the OLSR energy efficient by making effective neighbor selection based on residual battery energy of a node and...

As (network) software is such an omnipresent component of contemporary mission-critical systems, formal analysis is required to provide the necessary certification or at least formal assurances for these systems. In this paper we focus on modelling and analysing the Optimised Link State Routing (OLSR) protocol, a distributed, proactive routing protocol. It is recognised as one of the standard a...

Multipath routing protocols for Mobile Ad hoc NETwork (MANET) address the problem of scalability, security (confidentiality and integrity), lifetime of networks, instability of wireless transmissions, and their adaptation to applications. Our protocol, called MP-OLSR (MultiPath OLSR), is a multipath routing protocol based on OLSR [1]. The Multipath Dijkstra Algorithm is proposed to obtain multi...
متن کاملA multiple-metric QoS-aware implementation of the optimised link state routing protocol
The optimised link state routing (OLSR) protocol is one of the most promising for mobile ad hoc networks (MANETs). Despite numerous proposals for quality of service in MANET, there is a lack of OLSR implementations that efficiently support applications with stringent QoS constraints like VoIP or videoconference. In this paper, we present a QoS-OLSR implementation based on a multiple-metric appr...
