Abstract
In this paper, we propose an IP-based mobility management protocol named Fast handover Proxy Mobile IPv6 for Sensor networks (FPMIPv6-S). FPMIPv6-S provides network-based mobility support for 6LoWPAN WSN when a sensor node moves between two Personal Area Networks (PANs). It is an improved version of the Proxy Mobile IPv6 (PMIPv6) protocol proposed for mobility management in IPv6 networks. We compared via simulations FPMIPv6-S with other well-known mobility protocol namely Mobile IPv6. Performance results show that our proposed protocol achieves reduction of packet loss by as much 70% and improve the network throughput by over 25% compared to MIPv6. Further, we implemented our proposed protocol and MIPv6 with NS3 simulator and made extensive simulations runs to compare both protocols.
