doc.: IEEE sru 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 IEEE systems. This presentation provides our view on the SG and TG standardization process that could help RRMM spec development.

doc.: IEEE sru 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.

doc.: IEEE sru Submission Step 2: Establish evaluation methodology Jan 2014 Takashi Yamamoto, Sumitomo Electric IndustriesSlide 6 Define metrics to evaluate communication quality in the view point of application users. –Prioritize the evaluation items (throughput, delay, power consumption, etc.) for each application. –The problem is how to describe user experience such as connectivity, discovery, reachability, and mobility technically.

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

doc.: IEEE sru Submission MarMayJulSepNovJanMarMayJulSep Schedule Jan 2014 Takashi Yamamoto, Sumitomo Electric IndustriesSlide 8 The evaluation activity need enough discussion time, but we can’t repeat Step1~3 several times. 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

doc.: IEEE sru Submission Summary Jan 2014 Takashi Yamamoto, Sumitomo Electric IndustriesSlide 9 We proposed the standardization process of SRU. –Step 1: Clarify the RRMM requirements –Step 2: Establish evaluation methodology –Step 3: Evaluate new RRMM technologies Our intention is not to limit the discussion, but to activate the discussion by clarifying the issues at each step.
