TL;DR: This paper presents a comprehensive survey of significant efforts aimed at improving OSPF's convergence speed as well as scalability and extending O SPF to achieve seamless integration of mobile adhoc networks with conventional wired networks.
Abstract: Open Shortest Path First (OSPF), a link state routing protocol, is a popular interior gateway protocol (IGP) in the Internet. Wide spread deployment and years of experience running the protocol have motivated continuous improvements in its operation as the nature and demands of the routing infrastructures have changed. Modern routing domains need to maintain a very high level of service availability. Hence, OSPF needs to achieve fast convergence to topology changes. Also, the ever-growing size of routing domains, and possible presence of wireless mobile adhoc network (MANET) components, requires highly scalable operation on part of OSPF to avoid routing instability. Recent years have seen significant efforts aimed at improving OSPF's convergence speed as well as scalability and extending OSPF to achieve seamless integration of mobile adhoc networks with conventional wired networks. In this paper, we present a comprehensive survey of these efforts.

TL;DR: Performance measurements of the OLSR (optimized link state routing) protocol routing, presented at the IETF MANET (mobile ad-hoc network) working group for ad-Hoc networks, are presented.
Abstract: 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 protocol supporting nodes mobility In this paper, we present performance measurements of the Optimized Link State Routing (OLSR) routing protocol, having the status of IETF RFC The measurements are performed at CELAR site on a platform representative of military scenarios in urban areas This platform consists of ten routers, eight PDAs and laptops using a IEEE 80211b radio interface and implementing OLSR v7 Some nodes are mobile within vehicles The emphasis of the measurements is on the performance of the network (route repair, network convergence speed, user traffic performance) in presence of this mobility

TL;DR: This paper proposes a new routing protocol for ad hoc networks built around the source routing technique combined with the location of nodes obtained by an energy and distance smart dissemination mechanism that has reduced delay, and is more bandwidth and energy efficient, than both traditional (proactive and reactive) ad hoc routing protocols.
Abstract: This paper proposes a new routing protocol for ad hoc networks built around the source routing technique combined with the location (e.g., GPS coordinates) of nodes obtained by an energy and distance smart dissemination mechanism. The key new observation used is that the location information provides each node with a snapshot of the topology of the complete network from which a source route may be computed locally rather than through route discovery. The resulting protocol has reduced delay, and is more bandwidth and energy efficient, than both traditional (proactive and reactive) ad hoc routing protocols, as well as location based routing protocols.

TL;DR: This work examines the use of congestion information to avoid network hotspots, and results based on modifications to the dynamic source routing protocol (DSR) and TCP demonstrate substantial performance improvement in terms of scalability, packet delivery, overhead, and fairness.
Abstract: With most routing protocols for ad hoc networks, shorter paths are generally considered more desirable, making some areas of network more prone to congestion and decreasing overall network throughput. We examine the use of congestion information to avoid these network hotspots. By locally monitoring the network interface transmission queue length and MAC layer behavior at each node, a node can establish an approximation of the degree to which the wireless medium around it is busy; this measurement reflects not only the behavior of the node itself, but also the behavior of other nearby nodes sharing the wireless medium. We suggest a number of uses of such congestion information in an ad hoc network, in the network, transport, and higher layers, and we evaluate a set of such uses through simulation. Our results based on modifications to the dynamic source routing protocol (DSR) and TCP demonstrate substantial performance improvement in terms of scalability, packet delivery, overhead, and fairness resulting from this use of congestion information.
