Multipoint relays o er an optimized way of ooding packets in a radio network. However, this technique requires the last hop knowledge: to decide wether or not a ooding packet is retransmitted, a node needs to know from which node the packet was received. When considering broadcasting at IP level, this information may be di cult to obtain. We thus 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)
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. In particular, assuming that a mechanism for routing(More)
Trends in fourth generation (4G) wireless networks are clearly identified by the full-IP concept where all traffic (data, control, voice and video services, etc.) will be transported in IP packets. Many proposals are being made to enhance IP with the functionalities necessary to manage the mobility of nodes, so that networks can provide global seamless(More)
This paper introduces the FIT IoT-LAB testbed, an open testbed composed of 2728 low-power wireless nodes and 117 mobile robots available for experimenting with large-scale wireless IoT technologies, ranging from low-level protocols to advanced Internet services. IoT-LAB is built to accelerate the development of tomorrow's IoT technology by offering an(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)
Wireless ad-hoc networks are autonomous, self-configurating and adaptive. Thus, such networks are excellent candidates for military tactical networks, where their ability to be operational rapidly and without any centralized entity is essential. As radio coverage is usually limited, multihop routing is often needed; this is achieved by an ad-hoc routing(More)
Scalability is one of the toughest challenges in ad hoc networking. Recent work outlines theoretical bounds on how well routing protocols could scale in this environment. However, none of the popular routing solutions really scales to large networks, by coming close enough to these bounds. In this paper, we study the case of link state routing and OLSR, one(More)
