Mobility support in IPv6 networks (MIPv6) and Fast Handovers for Mobile IPv6 (FMIPv6) are already released as RFCs for many years. While the former focuses on maintaining the network connections when a mobile node handovers across subnets, the latter is built based on the former concept, but focuses on reducing the packet loss and latency inherent to the handover process. Performance study of both...
The third generation (3G) of mobile communications has been successfully standardized and implemented throughout the world. International Mobile Telecommunications-2000 (IMT-2000) technology is a representative realization of 3G technology. Currently IMT-2000 is evolving to a next generation standard named IMT-Advanced. Major milestone technologies that lead 3G in to the fourth generation (4G) standards...
Network mobility (NEMO) aims managing seamless connectivity for a group of mobile terminals as a whole mobile network. Multiple care of addresses (MCoA) registration scheme was also proposed to address seamless Internet connectivity issue. In this paper we first analyze the upload and download packet loss of mobile router (MR) in NEMO basic support protocol. Then the seamless Internet connectivity...
In this research, three honeycell WiFl architectures using the 802.11b and 802.11g protocols are studied. These architectures are designed to provide high mobility for dynamic data applications and are optimized for deployment in moderately populated areas. OPNET is used in the study as the network simulator. At the OPNET default value of the packet reception power threshold, it is found that the...
The multihop cellular network architecture has been actively studied due to its capability to significantly increase cellular system capacity and coverage, and at the same time greatly reduce the transmission range of mobile nodes. The majority of the literature on MCN, however, is based on discussions from the physical or link layer point of view. In this article we look at the logical MCN architecture...
