Abstract
This article presents a Hybrid Latency Low handover mechanism for PMIPv6 wireless networks (HLL-PMIPv6). It aims to provide ubiquitous Internet access for mobile host with a high-speed mobility environment. The HLL-PMIPv6 introduces a new entity called, iHLMA, which is responsible to coordinate mobile host's intra and inter handovers and maintains its communication continuously within and across PMIPv6 domains. The HLL-PMIPv6 reduces the mobile host's signalling processing latencies as well as its overhead costs. Moreover, the HLL-PMIPv6 makes a proficient efforts towards reducing the end-to-end latency by avoiding the triangular routing caused by the home domain's involvement in the traffic forwarding. Simulation evaluations have been conducted to reveal HLL-PMIPv6 superior improvement over the existing schemes. Simulation evaluations have been conducted to reveal HLL-PMIPv6 superior improvement over the existing schemes. The results show that the HLL-PMIPv6 can significantly improve the mobile host mobility performance by reducing the handover latency, traffic loss, protocol signalling cost, as well as the end-to-end latency.
