Abstract

Wireless Sensor Nodes (SNs), the key elements for building Internet of Things (IOT), have been deployed widely in order to get and transmit information over the internet. With the introduction of IPv6 over Low Power Wireless Personal Area Network (6LoWPAN), it is possible to connect these constrained devices to IPv6 Networks and transmit IPv6 packets. The sensor nodes are being deployed/installed on many objects and some of them are mobile (moving) including mobile gadgets, physical objects (living or non-living) etc. These mobile objects require sufficient Mobility Management Schemes to take care of data transmission. Host based mobility protocols; MIPv6 and its extensions are not suitable for these resource constrained devices. In this paper our focus is to study PMIPv6 based mobility management and different Scenarios based on it along with sensor devices. Existing research has made many improvements in terms of HO latency but less attention has paid towards signaling cost and packet loss particularly in time critical areas. The study provides the complete survey of network based mobility management schemes, 6LoWPAN mobility, challenges associated with them and solutions to meet these challenges.
