Purpose: To suggest some metrics which can be used to evaluate EEE802.15 TG10 final proposals Notice: This document has been prepared to assist the IEEE P802.15. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributor acknowledges and accepts that this contribution becomes the property of IEEE and may be made publicly available by P802.15.

  2. Some Points to Be Determined • 15.4 MAC modes to be operated • Beacon enabled mode or non-beacon enabled mode • In which mode is a proposed routing able to be operated? • Need to be defined • Intervals for Hello frames, etc. • Device (or node) deployment scenario • Network size • Number of nodes • Transmit power (or range) • Traffic distribution time • Deployment method (random or grid) • Simulation time • For how much time can simulation results be obtained?

  3. Possible Metrics (1) • Packet Delivery Ratio (PDR) • The fraction of application level data packets sent that are actually received at the respective destination node. • Packet Overhead • The number of transmissions of routing packets; for example, a reply packet for routing sent over three hops would count as three overhead packets in this metric. • Byte Overhead • The number of transmissions of overhead (non-data) bytes, counting each hop as above.

  4. Possible Metrics (2) • Mean Latency • The average time elapsed from when a data packet is first sent to when it is first received at its destination. • 99.99th Percentile Latency • Computed as the 99.99th percentile of the packet delivery latency. • Path Optimality • Compares the length of routes used to the optimal (minimum possible) hop length as determined by an off-line omniscient algorithm, based on the nominal wireless transmission range of 250 m per hop. • Construction time • Computed as time to establish a route. • The Tg10 group will decide whether association time will be included in this time.
