Commonly, duplicate address detection is performed when configuring network interfaces in order to ensure that unique addresses are assigned to each interface in the network. Such mechanisms commonly operate with the premises that a node ”intelligently” selects an address which…
The primary issue with respect to securing Mobile Ad hoc NETworks (MANETs) is that of ensuring network integrity even when the network is subject to attacks to break its connectivity. In this research report, we study how to secure the…
In this paper, we evaluate the performance of two MANET routing protocols under varying traffic, density and mobility conditions. We observe, that a rather large fraction of the traffic being carried on the Internet today carries TCP. Thus, Internet traffic…
This specification updates the Optimized Link State Routing Protocol version 2 (OLSRv2) with an optimization to improve the selection of routing multipoint relays. The optimization retains full interoperability between implementations of OLSRv2 with and without this optimization. IETF – Proposed…
Routing, and more precisely routing within an Autonomous System (AS), is the most basic and still outstanding wireless ad hoc networking challenge. As the properties of ad hoc networks are a priori unpredictable and may change dynamically during the lifetime…
Data delivery across a multi-hop low-power and lossy networks (LLNs) is a challenging task: devices participating in such a network have strictly limited computational power and storage, and the communication channels are of low capacity, time-varying and with high loss…
Public community Mobile Ad Hoc NETworks (MANETs), such as the “Funkfeuer” or “Freifunk” networks, scale up to several hundreds of routers, connecting users with each other, and with the Internet. As MANETs are typically operated over wireless channels (e.g. WiFi),…
This paper addresses the issues of automatic address and prefix configuration of MANET routers. Specifically, the paper analyzes the differences between “classic IP networks” and MANETs, emphasizing the interface, link, topology, and addressing assumptions present in “classic IP networks”. The…
The Optimized Link-State Routing protocol (OLSR) is a proactive link-state routing protocol. While similar to the well-known Internet routing protocol OSPF, OLSR is designed to be simple, and to maintain connec- tivity in face of highly dense and dynamic networks,…
Since the end of the 20th century, wireless networking is experiencing explosive growth, driven by the popularity of wireless telephony on one hand, and by the development of wireless computer networks on the other hand. Both trends are currently merging…
