Summary:
This paper proposes the architecture of light-weight IPv6 (LWIPv6) for low-power wireless personal area networks (LoWPANs), optimize the functions of the architecture’s protocols, and reports typical results from the power consumption simulation for LWIPv6. The LoWPAN architecture is oriented to a simple and low-cost wireless communication system, which allows wireless connectivity in a variety of applications with requirements of limited power and relaxed throughput. LoWPAN devices conform to the IEEE 802.15.4 standard specified by the IEEE Standards Society. This paper describes systems requirements analysis (SRA) of LoWPANs with regard to the Internet protocol (IP) layer, the architecture of LWIPv6, and its optimization and performance analysis. The proposed architecture and its protocols in LWIPv6 are substantially optimized for the IP stack, such as header compression, simplified neighbor discovery, and reduction of overhead in the Internet control message protocol (ICMP) functionality. The computer simulation of the proposed architecture is also implemented in the viewpoint of power consumption depending on neigh cache size.
