It is expected that the next-generation mobile and wireless communications will be supported by an all-IP based infrastructure and also need for an effective mobility management protocol to support ubiquitous network access by providing seamless handover. This is especially true with invention of portable mobile and laptop devices that can be connected almost everywhere at any time. However, the recent explosion on the usage of mobile and laptop devices has also generated several issues in terms of performance and quality of service. Nowadays, mobile users demand high quality performance, best quality of services and seamless connections that support real-time application such as audio and video streaming. The goal of this paper is to observe the impact and evaluate the mobility management protocols under micro mobility domain on link layer and network layer handover performance. Therefore, this paper proposes an integration solution of network-based mobility management framework, based on Proxy Mobile IPv6, to reduce handover latency when mobile host moves to new network during handover on high speed mobility. Simulations are conducted to analyze the relationship between the network performances with the moving speed of mobile host over mobility protocols. Based on simulation results, we presented and analyzed the results of mobility protocols under intradomain traffics in micro mobility domain.

Most of the wireless networks and mobile cellular networks are moving to be all IP based. These networks are connected through the private IP core networks using the TCP/IP protocol or through the Internet. As such, there is room to improve the mobility support through the Internet and support ubiquitous network access by providing seamless handover. This is especially true with the invention of portable mobile and laptop devices that can be connected almost everywhere at any time. However, the recent explosion on the usage of mobile and laptop devices has also generated several issues in terms of performance and quality of service. Nowadays, mobile users demand high quality performance, best quality of services and seamless connections that support real-time application such as audio and video streaming. The goal of this paper is to study the impact and evaluate the mobility management protocols under micro mobility domain on link layer and network layer handover performance. Therefore, this paper proposes an integration solution of network-based mobility management framework, based on Proxy Mobile IPv6, to alleviate handover latency, packet loss and increase throughput and the performance of video transmission when mobile host moves to new network during handover on high speed mobility. Simulations are conducted to analyze the relationship between the network performances with the moving speed of mobile host over mobility protocols. Based on simulation results, we presented and analyzed the results of mobility protocols under intra-domain traffics in micro mobility domain.

resolving issues related to the layer 3 mobility management. It
is an efficacious mobility management protocol for next
generation wireless networks that employs the same concepts
as used in Mobile IPv6, but altered to operate in the network
part only in place of involving the Mobile Host as well. Even
though PMIPv6 offers many advantages, but it still undergoes
from lengthy handover latency which is not acceptable for
real time applications. In order to reduce the long latency
during handover, a seamless handover unified solution has
been proposed. The motivation of this research is to simulate,
analyse and evaluate the performance of video transmission
over Proxy Mobile IPv6 in a micro mobility domain on linklayer
and network layer. Simulations were also conducted in
two levels which are frame and packet levels to analyse and
evaluate the association between during handover over
network-based mobility management protocols and the
network performances with the moving speed of mobile host.

In this context, seamless is referred to users that are free to roam around different networks and at the same time stay connected without any disturbance to the ongoing session during the handover process from one network to another. The handover process between these networks spawns long delay or latency, high packet loss, and fewer throughputs which may degrade the performance of real-time applications during the handover process. Therefore, in order to resolve these problems, a new protocol has been proposed by Network-based Localized Mobility Management working group of Internet Engineering Task Force under network-based mobility management protocol. Although, this protocol managed to minimize the problems related to network switching, it still suffers several drawbacks during the handover process especially when the movement speed of mobile user is high. In this paper, we present a new approach which is a network-based mobility management protocol that aims to reduce the lengthy handover latency, jitter, high packet loss, and increase throughput and the performance of video transmission during the high speed mobility. The proposed approach namely Seamless Handover Integrated Solution consists of mobility prediction method, a set of Internet Control Message Protocol version 6 (ICMP6) messages which are effective in terms of handover optimization.

However, PMIPv6 still suffers from lengthy handover latency and packet loss during the handover when Mobile Host moves to a new network. In order to improve the performance of PMIPv6, we proposed an integrated solution scheme with Media Independent Handover (MIH) and neighbor discovery message of IPv6 to reduce handover latency and packet loss. The proposed protocol does not have method to prevent from security threats such as replay attack and key exposure when mobile host first enters in PMIPv6 domain. In order to address this problem, we proposed one-time key with Diameter Message authentication framework which is based on the one-time key generation authentication protocol. It is expected the proposed framework is able to enhance security as well as reduce authentication latency.
