In delay- and disruption-tolerant wireless communication networks, capacity is commonly traded off for delay. That is the case of spatial intermittent connectivity (SIC) networks. SIC networks are designed to provide high data rates to mobile nodes in small disjoint geographical areas. However, because of userspsila mobility, these high data rates come at the expense of significant connectivity delay...
Seamless IP mobility protocols like Fast Mobile IPv6 (FMIPv6) requires the knowledge of candidate access routers, to which the mobile node will hand over its connection to, well in advance while the mobile node is still connected to its current AR. The candidate access router discovery (CARD) protocol is one such protocol that provides the identity and capabilities information of the candidate access...
The media independent handover (MIH) architecture is designed to facilitate the signaling and enable seamless handovers in heterogeneous networks. In this paper, we propose a solution using the stream control transmission protocol (SCTP) to efficiently carry MIH messages. The solution uses SCTPpsilas multihoming and multistreaming capabilities along with cross-layer information available through the...
The challenge in the coming years for mobile networks will be to offer high bit rate data services to customers in mobility. Future mobile architectures are being standardized to offer mobility between heterogeneous access technologies. The design of these architectures does not take into account scalability requirement since they are centralized with many network levels and dependency. This paper...
