Use of proxy mobile ipv6 for Group mobility management in Coap-based iot networks

Abstract

From past few years, the new technology Constrained Application Protocol (CoAP) has been graded for many sensor devices in the field of Internet of Things. Recently, the two basic mobility scheme approaches were proposed 1: Centralized CoAP and CoAP PIMPIPv6 which was applied in order to reduce handover delays in the mobile network devices. However, these past mobility schemes focus on single sensor device therefore no any solution for the group sensors, so there is need to introduce a mobility scheme that work in group condition having more than one sensor. To address this limitation of past mobility schemes, in this dissertation, addition of group sensors will be done on the existing scheme CoAP PMIPv6. It becomes CoAP PMIPv6 Multi sensors. As each sensor is directly communicating with the gateway, this causes a big problem in terms of signaling cost and handover delay. A solution to this problem will be provided where Personal Device will be added on the sensors end, and as the sensors will be on human body then WBAN supported protocols will be used, which causes the reduction of handover delay and signaling cost.
