Abstract
Constrained application protocol (CoAP) can be used for message delivery in wireless sensor networks. Although CoAP-based proxy mobile internet protocol (PMIP) was proposed for mobility management, it resulted in handover delay and packet loss. Therefore, an enhanced PMIP version 6, with partial bicasting in CoAP-based internet of things (IoT) networks, is proposed. Here, when an IoT device moved into a new network, the corresponding mobile access gateway (MAG) updated the local mobility anchor (LMA) binding. Further, LMA initiated the “partial” bicasting of data packets to the new and the previous MAGs. The data packets were buffered at the new MAG during handover and were forwarded to Mobile Node (MN) after the handover operations. The proposed scheme was compared with the existing scheme, using ns-3 simulations. We demonstrated that the proposed scheme reduced handover delays, packet losses, end-to-end delay, throughput, and energy consumption, compared to the existing scheme.

Summary
Wireless networks are the principal mechanisms for establishing computer networks through wireless connections among the nodes of a network [1]. Wherein IP operates from a mobile user to access point (AP), link wireless systems to the internet. In 2018, the advent of high-end communication technology and user-friendly devices saw the development of wireless body networks (WBANs) and a dedicated human body network that monitored, directed, and communicated various vital functions, including blood pressure, temperature, and electrocardiogram (ECG), etc. Among mobile nodes (MNs), mobile access gateway (MAG) and local mobility anchor (LMA), MN moves among networks to facilitate the smooth running of sessions, reduce packet loss, and avoid handover delays in mobility management significance. MAGB senses the mobile node detachment and ensues the proxy binding update (PBU) functions, with a local mobility anchor to remove the binding state This is further linked with the mobile node simultaneously, thereby, resulting in handover delay and packet loss. We demonstrate that the proposed scheme could reduce handover delays, packet losses, end-to-end delay, throughput, and energy consumption, compared to the existing scheme
