Simple 6LoWPAN mesh end-node improves network performance reference design

TIDA-010003

Design files

Overview

This reference design implements a simple RF mesh network end node 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 CC1310 SimpleLink™ Wireless MCU to optimize performance 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.

Features
  • IPv6 networking over low-power RF in the <1GHz ISM bands
  • Implements mesh network protocols of 6LoWPAN, RPL, IPv6/ICMPv6 and UDP
  • Implements TI-15.4 stack with IEEE 802.15.4e based frequency hopping and MAC data encryption
  • Software layer architecture identical to Wi-SUN FAN v1.0
  • Supports low-power mode configuration for the battery-powered end nodes

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.

Important note

This reference design contains example software for implementing 6LoWPAN networks based on the Contiki-OS RTOS. This example implementation included the uIP TCP/IP stack, identified to be potentially vulnerable outlined in the following advisory: Amnesia open-source TCP/IP stack vulnerabilities (AMNESIA:33).

We have discontinued this example software and recommend you evaluate our Wi-SUN solution. If you plan to use the previous version of this reference design, please note it is considered OBSOLETE, and there is no plan to update it at this time. It is recommended that TI customers who referenced example software that included Contiki-OS evaluate the recommendations provided by the ICS Advisory and either:

  1. Ensure to take appropriate actions to mitigate these potential vulnerabilities in Contiki-OS, or
  2. Move to Contiki-NG 4.6.
