In this paper we propose and discuss an optimized link state routing protocol, named OLSR, for mobile wireless networks. The protocol is based on the link state algorithm and it is proactive (or table-driven) in nature. It employs periodic exchange of messages to maintain topology information of the network at each node. OLSR is an optimization over a pure(More)
In this paper we discuss the mechanism of multipoint relays (MPRs) to efficiently do the flooding of broadcast messages in the mobile wireless networks. Multipoint relaying is a technique to reduce the number of redundant re-transmissions while diffusing a broadcast message in the network. We discuss the principle and the functioning of MPRs, and propose a(More)
In this paper, we examine security issues related to proactive routing protocols for MANETs. Specifically, we investigate security properties of the Optimized Link-State Routing Protocol one example of a proactive routing protocol for MANETs. We investigate the possible attacks against the integrity of the network routing infrastructure, and present(More)
We analyze the performance of ad hoc pro-active routing protocol OLSR. In particular we focuse on the multipoint relay concept which is the most salient feature of this protocol and which brings the most signiicant breakthrough in performance. We will anlyse the performances in two radio network models: the random graph model and the unit graph. The random(More)
We analyze the performance of ad-hoc routing as deened in MANet IETF working group in the random graph model. In particular we analyze the performance of a reactive protocol DSR and of a pro-active protocol OLSR. The random graph model is deened by the number of nodes n, and link probability p. We give the asymptotic evaluation of the ooding distance which(More)
The paper addresses the problem of motion autonomy of cybercars across an urban intersection. Cybercars are small electric city vehicles aimed at navigating autonomously. In the context of a crossing, the motion generation together with its safety is critical issues. The proposed approach to the problem lies in the coupling of perception and planning(More)
Peer-to-Peer (P2P) technology has been shown to be effective for content delivery on the Internet. Its applications such as video streaming on Mobile Ad hoc NETwork (MANET) has been explored while the issue of live video streaming on MANET is still a real challenge due to frequent changes in network topology, and the sensitiveness of radio links. To combat(More)
Mobile ad hoc networks (MANETs) are infrastructure-free, highly dynamic wireless networks, where central administration or configuration by the user is very difficult. One of the MANET protocols which have been recently promoted to experimental RFC is the OLSR routing protocol (Jacquet et al., 2003; Jacquet et al., 2001), on which this article focuses. This(More)
