In the fast handover, when a mobile node moves to...

In Mobile IPv6 especially in Hierarchical Mobile IPv6 (HMIPv6), Mobile Node’s handoff performance is greatly impaired by the Duplicate Address Detection (DAD) procedure for the newly formed Care-of Address. Based on the data gathered from our HMIPv6 test bed, this paper analyzed the origin of such performance degradation. To alleviate the impact of DAD on handoff performance, Greg Daley et al p...

Mobile IP allows a mobile node to roam into a foreign IP network without losing its connection with its peer. Mobile IPv6 uses Route Optimization to improve the routing performance by avoiding the triangle routing problem and adopting Return Routability as a secure process for binding update. Host Identity Protocol (HIP) is an experimental security protocol which provides mobility management an...

In this paper, our aim is to evaluate and analyze two propagation methods over mobile IPv6 networks which are bidirectional tunneling and routing optimization and both deliver a packet from a correspondent node to the mobile node and vice versa via specific tunnel. To this end we propose a mobile IPv6 scenario by including real-time applications such as video-conferencing. As a result of the ev...

-Cyber-attacks are increasing day by day. Each time attackers or malicious users come up with new techniques or methods in order to harm the network system of particular organization. While attacking on any organization, the main focus of the attacker is to successfully launch attack against organization’s network system by hiding its own identity under the identity of other legitimate user in ...

Mobile IP has been developed to handle mobility of Internet hosts at the network layer. Mobile IP, however, suffers from a number of drawbacks such as requirement of infrastructure change, high handover latency, high packet loss rate, and conflict with network security solutions. In this paper, we describe and evaluate the performance of SIGMA, a Seamless IP diversity based Generalized Mobility...

TCP/IP is currently the standard network protocol for wired Internet. To make all Internet services available to all mobile users, a Mobile IP is proposed. Another important development for TCP/IP is the evolution to the next generation Internet, the protocol for which is called IPv6. Whether using IPv4 or IPv6, situations arise in some Internet applications where a piece of data needs to be se...

The paper proposes a communication model of implementing an Anycast service in an Ad Hoc network which is connected to IPv6 networks where IPv6 nodes can obtain the Anycast service provided by the Ad hoc network. In this model when an Anycast mobile member in an Ad hoc network moves it can keep the existing communications with its corresponding nodes to continue providing the Anycast services w...

The growing numbers of mobile users challenge cellular network scalability. The IPv4 address space is not sufficiently large to uniquely identify all active network devices, while at the same time network address translation (NAT) middleboxes used to extend the IPv4 address space introduce performance overheads. Therefore, ISPs have started to adopt IPv6 addressing to provide Internet services ...

Mobile IP provides an efficient and scalable mechanism for achieving host mobility over the Internet. Using Mobile IP, mobile nodes may change their points of attachment to the Internet without changing their IP addresses. However, this will results in a high signaling cost of updating the location of a mobile node if it moves frequently. In this paper, we propose a lazy update strategy for min...
