To minimize the large handover delays associated with mobile IPv6 numerous micro-mobility protocols were proposed. In this paper, we consider the mobility agent (MA) based family of micro-mobility protocols such as hierarchical mobile IPv6 and proxy mobile IPv6 and focus on the issue of the bottlenecks that MAs can lead up to under high network load. We propose a Dynamic QoS aware route optimization...
The next generation broadband wireless access networks are expected to support a variety of multimedia rich applications which can lead to very high traffic demand. With the development of high speed radio access technologies the backhaul network can become the bottleneck if not upgraded and configured optimally to support the expected increase in date rates and traffic demands. To deliver high data...
From a network perspective, the major challenge in providing seamless connectivity whilst maintaining the required level of QoS to users results from the negative interactions that occur between mobility and QoS. These interactions, particularly those of mobility and QoS, have been the subject of much research. In this paper, we discuss the various approaches that have already been taken to combine...
With the advent of various access technologies and increasing number of applications, a set of challenges concerning efficient delivery of ubiquitous services to heterogeneous users and devices have been posed. One of the important challenges is to integrate quality of service (QoS), security and mobility support in heterogeneous networks. To facilitate the interworking of these mechanisms we propose...
