Abstract--In next-generation wireless networks, mobile nodes (MNs) need to freely change their network attachment point while communicating with others. Accordingly, it is crucial for mobile operators to provide efficient seamless mobility support. Several mobility protocols have been standardized by the working groups of the Internet Engineering Task Force (IETF). However, none of them can provide seamless mobility support for users in the next-generation wireless network. This paper proposes a new seamless mobility support protocol, and presents performance comparison with existing mobility protocols, such as MIPv6 and its enhancements.

“…This pre-selection reduces the FLC complexity and saves the processing time. However, this scheme faces the similar constraints as the one presented by [13]. Apart from those limitations, this scheme is applicable for small environmental variations and not adaptable to the new network conditions [14], [15] [16], [17].…”

Abstract-The importance of network selection for wireless networks, is to facilitate users with various personal wireless devices to access their desired services via a range of available radio access networks. The inability of these networks to provide broadband data service applications to users poses a serious challenge in the wireless environment. Network Optimization has therefore become necessary, so as to accommodate the increasing number of users' service application demands while maintaining the required quality of services. To achieve that, the need to incorporate intelligent and fast mechanism as a solution to select the best value network for the user arises. This paper provides an intelligent network selection strategy based on the user-and network-valued metrics to suit their preferences when communicating in multiaccess environment. A user-driven network selection strategy that employs Multi-Access Service Selection Vertical Handover Decision Algorithm (MASS-VHDA) via three interfaces; WiFi, WiMAX and LTE-A is proposed, numerically evaluated and simulated. The results from the performance analysis demonstrate some improvement in the QoS and network blocking probability to satisfy user application requests for multiple simultaneous services.

“…Regarding the involved technologies, a handover can be categorised either as horizontal or vertical [18]. A horizontal handover denotes a change in the point of attachment to the network within the same access technology, while a vertical handover a switch between different access technologies.…”

The latest explosive growth in mobile networks has resulted in an increasing interest in optimisation techniques for mobile services. Resent advances in mobile wireless networks incorporate link-layer intelligence in order to enhance the performance of network and application layers. The Media Independent Handover (MIH) standard provides a framework that can make such link-layer intelligence available to upper layers. In this paper, a novel MIH-enabled playout algorithm for Voice over Internet Protocol applications is presented that aims to compensate for the degradation of voice quality caused by handovers. To that end, link-layer triggers in conjunction with speech time-scale modification techniques are exploited to mitigate the increase in delay and jitter induced by the handover process. Results of subjective listening tests show typical gains of 0.3 on a 5-point scale of the Mean Opinion Score with respect to existing playout scheduling schemes. AQ1
