Secured 6LoWPAN mesh end-node with enhanced network capacity reference design
Description
This reference design implements an RF mesh network end node with DTLS security for smart meter Advanced Metering Infrastructure (AMI) networks. The network is an IPv6 over low-power wireless personal area networks (6LoWPAN) solution. The design implements this network in a single CC1312R SimpleLink™ Wireless MCU to enhanceperformance and minimize system cost. The complete 6LoWPAN mesh network runs on top of the TI-15.4 stack based on IEEE 802.15.4e/g protocols and implements an un-slotted channel hopping (USCH) mode to provide protection against network interference. Network capacity is improved and the security is enhanced compared to TIDA-010003 end node design with the inclusion of larger neighbor and routing tables that optimize packet routing decisions.
