3. doc.: IEEE 802.15-14-0049-00-0sru Submission Abstract Jan 2014 Takashi Yamamoto, Sumitomo Electric IndustriesSlide 3 An evaluation methodology for SRU should be substantially discussed in order to assess gains relative to legacy IEEE802.15.4 systems. This presentation provides our view on the SG and TG standardization process that could help RRMM spec development.

4. doc.: IEEE 802.15-14-0049-00-0sru Submission Step 1: Clarify the RRMM requirements Jan 2014 Takashi Yamamoto, Sumitomo Electric IndustriesSlide 4 Collect the requirements of the RRMM use cases and narrow down the target of SRU. –Applications Example: position estimation, periodic monitoring, etc. –Traffic models of sensors and actuators packet size, interval, event probability –Deployment methods numbers of gateways and devices additional deployment is possible or not initial channel settings –etc.

7. doc.: IEEE 802.15-14-0049-00-0sru Submission Step 3: Evaluate new RRMM technologies Jan 2014 Takashi Yamamoto, Sumitomo Electric IndustriesSlide 7 Analyze the issues of the legacy IEEE802.15.4 RRMM technologies and collect the solutions. –Simulation is one of potential evaluation methods. –IEEE802.15 MAC/PHY may be abstracted boldly to use the existing network simulation software. Summarize how to approach the issues in the SRU standardization activity.

Therefore, we propose that we schedule this work clearly and advance it systematically. –Guidelines for Step1~3 proposals will be roughly determined in order to collect contributions widely. Step 2: Evaluation Methodology Step 1: Requirements Step 3: Proposal of new technologies
