: The privacy enabled IPv6 addressing mechanism ensures the privacy of node's identification in the communication messages. It makes adversaries difficult to track nodes and link any activities with the node's IP or the MAC address. Scalability of the privacy enabled IPv6 addressing scheme for 6LoWPAN may be affected due to underlying MAC layer mechanisms. Hence, this study aims to explore such impact. Addressing scheme is implemented in Contiki operating system which uses duty cycling at the MAC layer along with CSMA channel access mechanism. ContikiMAC and CXMAC are widely used duty cycling protocols in Contiki. An analytical study is presented in this paper, which analyses the IPv6 address configuration delay with ContikiMAC and CXMAC. Simulation is performed to corroborate the presented analytical model. The address configuration latency limits the scalability of the network. Hence, this paper studies the impact of duty cycling of the nodes on the address configuration latency and estimates the size of a single hop PAN. It is observed that ContikiMAC duty cycling protocol can achieve better performance compared to CXMAC protocol in terms of address configuration latency. In order to make up for the delay due to duty cycling, network can be divided into multiple PANs of smaller size where addressing process runs simultaneously.

This paper proposes a secure home healthcare system based on 6LoWPAN WSN. In this system, the hierarchical architecture based on clusters is proposed, and the hierarchical address structure based on location information is presented. Based on the architecture and the address structure, the secure address configuration algorithm is proposed. According to the destination IPv6 address, this system can automatically perform the routing in the link layer without route discovery. This system achieves the secure communication. Through this system, at any time a physician can monitor the physical parameters of a home-based patient such as a senior or less-mobile person, and a home-based patient can also alert a physician to call for help. In the latter case, the physician can quickly obtain the location of the patient in order to perform effective and timely treatment. The performance parameters of this system are evaluated and compared, and the data results show that this system effectively improves the system performance.
