A Mobility Management Architecture For Internet of Things Using Coap

In anInternet of Things (IoT) environment, IoT devicesare normallyused to transmit signal messages through unreliable wireless networks. However, because of the mobile nature of IoT devices, they end up losing connection to the network, thus leading to the loss of valuable signals at the monitoring end.Standard mobility management protocols like MIPv6 and its extensions may not besuitable to cope with this problem in an IoT environment, because they do not consider the constrained processing and power limitation of IoT devices. In this article we presenta system architecture for IoT mobility management using IETF Constrained Application Protocol (CoAP). Utilizing the inherent property of CoAP such as low signaling overhead, simple architecture, and reliable data transmission mechanism, the IP connectivity of resource-constrained IoT devices can be efficiently maintained during handover operation. Detailed architecture and algorithm for the proposed mechanism are presented. Finally, a testbed has been constructed to evaluate the performance of the proposed architecture.
