Integrated algorithm of HMIPv6 & MPLS for ns to support next generation wireless networks

The paper highlights the advantages of HMIPv6 (hierarchical Mobile IPv6) and MPLS integration in the aspect of guaranteed and efficient end-to-end QoS provision in multi-domain wireless networks. The multiple domain scenario of radio access networks is considered and we focus on traffic transmission from/to a mobile host (MH) and a correspondent node (CN). Agent advertisement, MH registration, label switched path establishment and maintenance, and data transfer procedures are described. Intra-domain and inter-domain soft handover is discussed in the context of multiple domain wireless access networks. A novel network simulator algorithm, suitable for ns2 (Kevin Fall, K.V., 2003), which integrates the functionalities of the two technologies (HMIPv6 and MPLS) is proposed and the structural parts of the block diagram are explained in detail.
