Wireless Sensor Nodes (SNs) in Internet of Things (IOT), have revolutionized and changed the perspective of 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. Mobility of such devices is achieved by deploying/installing them on many mobile (moving) objects including mobile gadgets, physical objects (living or non-living) etc. Therefore it requires sufficient Mobility Management Schemes for data transmission. Host based mobility protocols; MIPv6 and its extensions are not suitable for resource constrained devices. In this paper, our focus is to study PMIPv6 based mobility management and different Scenarios based on it along with sensor’s mobility. Although 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 and challenges associated with them.
