—Cross-layer mechanism, for which a protocol locating at a given layer uses information issued from other layers, may enhance the mobile networks performance. Some of those mechanisms are based on mobility metrics. For example, the establishment of a route by choosing less mobile nodes could improve the routing protocol. In this paper, we study the ability(More)
This paper presents a cluster-based extension of the DSR protocol called cluster source routing (CSR). The proposed approach improves the scalability of DSR in high-density and low-mobility networks. The originality of our proposal is an adaptive use of DSR and CSR routing modes according to network density and node mobility in order to produce less(More)
For extremely dynamic networks, such as ad-hoc, the topology change awareness has a crucial impact on the routing performance and consequently many routing protocols adapt their processes to the state of the network, from some network awareness. While several works have already been done on routing adaptations, this paper is more focused on the network(More)
Satellite payloads are becoming much more complex with the evolution towards multimedia applications. Moreover satellite lifetime increases while standard and services evolve faster, necessitating a hardware platform that can evolves for not developing new systems on each change. The same problem occurs in terrestrial systems like mobile networks and a(More)
As multihoming refers to a situation where a node can choose between several paths, the MANET networks that are mobile networks without infrastructure offer naturally a multihoming feature. It is managed at the network level by the routing protocol. Multihoming capacity is also present in the IETF transport protocol SCTP. In this work we consider(More)
Numerous studies have shown the difficulty for a routing protocol to scale to large wireless networks. Ad hoc routing protocols have to cope with an increasing node density and a significant number of nodes. DSR has been supported by the Manet working group as an IP routing protocol adapted to multi-hop wireless ad hoc networks [1,2]. DSR is a reactive(More)
