Mobile IP est une solution pour prendre en charge la mobilité des hôtes sur Internet. Mais des paquets peuvent être perdus pendant les périodes de détection de mouvement et d’enregistrement du Mobile IP. Le TCP standard interprète ces pertes de paquets comme des signes de congestion du réseau, il réduit donc son taux de transmission en réduisant la taille de sa fenêtre et son seuil de démarrage lent. En outre, les multiples pertes de paquets survenant lors des transferts déclenchent des délais d'attente de retransmission successifs au niveau de l'expéditeur TCP, provoquant une longue pause de communication même une fois le transfert terminé. Ensemble, ces éléments conduisent à une dégradation significative du débit. Dans cet article, nous proposons deux nouveaux schémas TCP pour réduire les pertes de paquets et atténuer les effets des transferts sur les performances TCP. TCP-MD (Movement Detection) est proposé pour réduire les pertes de paquets en détectant un transfert plus tôt, et TCP-R (Registration) est conçu pour empêcher les pertes de paquets en gelant la transmission des données pendant l'enregistrement. Les schémas proposés maintiennent la sémantique TCP de bout en bout, permettant une interopérabilité totale avec l'infrastructure existante. Seule une petite modification est requise dans l'hôte mobile, et la mise en œuvre est simple car certains messages Mobile IP sont utilisés pour notifier le transfert, éliminant ainsi le besoin de messages supplémentaires. Les simulations ont confirmé que les schémas proposés peuvent donner d'excellentes performances dans un environnement où l'hôte mobile subit de fréquents transferts.

Abstract: Mobile IP is a solution to support host mobility in the Internet. But, packets can be lost during the movement detection and registration periods of the Mobile IP. Regular TCP interprets theses packet losses as signs of network congestion, so it reduces its transmission rate by reducing its window size and slow start threshold. Besides, the multiple packet losses occurring during handoffs trigger successive retransmission timeouts at the TCP sender, causing a long communication pause even after handoff is completed. These together lead to significant throughput degradation. In this paper, we propose two new TCP schemes to reduce packet losses and to alleviate the effects of handoffs on TCP performance. TCP-MD (Movement Detection) is proposed to reduce packet losses by detecting a handoff earlier, and TCP-R (Registration) is designed to prevent packet losses by freezing data transmission during registration. The proposed schemes maintain end-to-end TCP semantics, making it possible to fully interoperate with the existing infrastructure. Only a small change is required in the mobile host, plus the implementation is simple because some Mobile IP messages are used to notify the handoff, eliminating the need for any additional messages. Simulations confirmed that the proposed schemes can give an excellent performance in an environment where the mobile host experiences frequent handoffs.
