[Tinyos-help] Rationale for 29 bytes payload

2006-04-21 Thread Vinai Sundaram
Hi , I need to send more than 29 bytes for the application I am working on. However, I do not want to increase the payload size so much that it will reduce the throughput of the network. Is "29 bytes" found to give close to optimal throughput? Are there any empirical/analytical studies that s

Hi,This is great to know! Apart from this topic there was also a discussion on April 7 on the maximum payload size that we could use up to 128 bytes for IEEE 802.15.4 radio compliant platform. http://mail.millennium.berkeley.edu/pipermail/tinyos-help/2006-April/015912.htmlCould somebody shed some
