Cost-Effective and distributed mobility management scheme in sensor-based PMIPv6 networks with SPIG support

Due to limited resources, the slow progressive development of wireless sensor networks (Wireless Sensor Network) through the development of hardware and power management technology is currently in progress for the development of the latest IP-based IP-WSN. Those with low-power devices on IPv6 can mount the 6LoWPAN (IPv6 over Low power WPAN) this is getting attention. In these IP-based sensor networks, existing IP-based schemes, which were impossible in wireless sensor networks, become possible. 6LoWPAN is based on the IEEE 802.15.4 sensor network and is a technology developed for IPv6 support. The host-based mobility management scheme in IP-WSN is not suitable due to the additional signaling; the network-based mobility management scheme is suitable. In this paper, we propose an enhanced PMIPv6 route optimization, which considers the multi-6LoWPAN network environment. All SLMA (Sensor Local Mobility Anchor) of the domain 6LoWPAN is connected to the SPIG (Sensor Proxy Internetworking Gateway) and perform cross-domain distributed mobility control. All information of SLMA in the 6LoWPAN domain is maintained by SMAG (Sensor Mobile Access Gateway) and route optimization is performed quickly and the route optimization status information from SPIG is stored to SLMA and is supported without additional signaling.
