A Novel Intra-Domain Continues Handover Solution for Inter-Domain Pmipv6 Based Vehicular Network

Author 1: Haidar N Hussain Author 2: Kamalrulnizam Abu Bakar Author 3: Shaharuddin Salleh

IP mobility management protocols (e.g. host based mobility protocols) incur significant handover latency, thus aggravate QoS for end user devices. Proxy Mobile IPv6 (PMIPv6) was proposed by the Internet Engineering Task Force (IETF) as a new network-based mobility protocol to reduce the host based handover latency. However the current PMIPv6… Read full abstract & cite →
