In response to the emerging deployment of IPv6 on network devices, this paper proposes the integration of IPv6 on Lock-Keeper, an implementation of a high level security system for preventing online attacks. It is designed to permit the secure data exchange over physically separated networks in an IPv4-based environment. A new intercommunication module is added to manage IPv4/IPv6 handoff inside the...
For accessing various resources via mobile device anytime anywhere, the heterogeneous access technologies between wired and wireless networks have been developed and integrated actively. However, real-time services, e.g., Voice over IP (VoIP) and video streaming suffer from long delay, and non-real-time connections, e.g., TCP connections, cause low transmission throughput while occurring timeout and...
The transition between the IPv4 Internet today and the IPv6 Internet will be a long process during both protocols coexists and also it is unreasonable to expect that many millions of IPv4 nodes will be converted overnight. Mobility is becoming ubiquitous now-a-days. This paper is presented with a survey on the three IPv4-IPv6 transition mechanisms, how these mechanisms are incorporated in the various...
The evolution of the 3rd Generation Partnership Project (3GPP) network is expected to increase network performance and quality with reduced operational costs and complexity. It becomes critical to provide seamless mobility support in such heterogeneous access networks. In this article we examine the existing mechanisms and protocols and exploit the autonomic features based on the current specifications...
Mobility is not natively supported in the current Internet because it uses IP addresses as host or session identifiers in the transport and application layers and as locators in the network layer. In the mobile networking environment, a host should be able to change its locator when it moves from one network to another, while keeping the host or session ID fixed. Thus, to provide inherent mobility...
The NEMO basic support protocol is a home agent based technique (derived from mobile IPv6) that permits the mobility of a network of IPv6 devices to be supported through the use of a dedicated mobile router. This NEMO mobile router accepts connections from IPv6 nodes and transparently manages any IP mobility on their behalf, which means that as well as individual hosts, a NEMO mobile router can also...
In this paper we propose a hybrid radio access network architecture that aims to connect remote areas to broadband networks. The proposed architecture consists in a WiMAX network for final users which hence can be connected to the internet backbone. In the other hand the WiMAX base stations are connected via the satellite to the wired network to circumvent mobility and long distance issues. To allow...
Cellular IP is one of well-known micromobility protocols. In this paper, its signaling cost for mobility management, including both route-update and paging-update packets, is numerically analyzed. An analytical method is presented and the numerical results is extensively compared and discussed over some important system parameters.
In all-IP wireless networks, groups of cells are served by IP access gateways. When users move between regions served by different gateways, IP and application layer mobility signaling is triggered. The key performance indicator to assess a given mobility protocol is the mean number of gateway handoffs. In this paper, we propose a new fundamental approach, which majorly extends past work in cellular...
The success of next generation wireless networks will rely much on advanced mechanisms for seamless mobility support among emerging heterogeneous technologies. Currently, mobile IP is the most promising solution for mobility management in the Internet. Several IP micro mobility approaches have been proposed to enhance the performance of mobile IP which supports quality of service, minimum packet loss,...
After the great deployment and success of the Wireless Local Area Networks based on access points, which communicate by using wired links, the wireless world saw the birth of new technologies like Ad Hoc networks and Wireless Mesh Networks (WMN), which permit the flexibility, easy deployment and low cost. The first objective of these networks is to offer a seamless connectivity to mobile users. Nevertheless,...
The capabilities of the wireless networks are continuously being enhanced to meet ever growing demand of the higher data rates for accessing wide range of Internet services in the mobile node. The IEEE 802.16e mobile worldwide interoperability for Microwave Access (WiMAX), 3GPP long term evolution (LTE) and 3GPP2 ultra mobile broadband (UMB) wireless technologies are identified as next generation...
In the new area of heterogeneous environments, roaming users, using multi-interface mobile terminals, need to access to services anytime and anywhere. For that, a seamless vertical handover has to be considered. In our paper, we propose a 3G/UMTS-WLAN loosely-coupled interworking architecture with mobile IP as a service continuity solution. We focus on a mobile-controlled vertical handover management...
In this paper, we propose a suitable set of protocols schematically combining both radio handover and IP handover for heterogeneous network with the enhancement of relay nodes, that is considered as an important feature of the future radio network. Based on that, we develop the functional allocation of media independent handover entities for a 4G communication system developed by the European WINNER...
Based on the comparison of congestion control between aeronautical telecommunication network (ATN) and IP network, a new congestion avoidance model considering the explicit congestion notification (ECN) in ATN over IP scheme, called explicit congestion notification in tunnel (ECNT) model, is proposed in this paper. In addition, a new ECN/CE mapping algorithm to map ECN signal in IP sub-network onto...
One of the most critical aspects in mobility management is handoff. Handoff is a complex process involving location identification, performance evaluation of available networks at that location, decision to switch to a different network and actions to effect the switching. During the process of handoff, the communication channel between the mobile host and a corresponding host may be broken, and this...
