Abstract
wireless sensor networks (WSNs) are f nding application in numerous f elds. For many of these applications, some or all of the sensor nodes are mobile. Mobility management in WSNs is a challenging and has been the subject of intensive research.
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 PMIPv6 protocol proposed for mobility management in IPv6 networks. FPMIPv6-S messages are carried by RPL protocol.
We integrated the FPMIPv6-S protocol in the NS-3 simulator and performed a thorough performance comparison of FPMIPv6-S and RPL. Simulation results of the proposed protocol shows signif cantly improved performance with respect to three QoS criteria: (1) the packet loss rate; (2) and the Throughput.
