TDMA MACresult analysis

[Shenlei Shen]

This is my tdma MAC result  , but I am confused with this result.

Firstly ,the tx or rx time changd from 0.00487913 to 15.0085 

suddenly, I am wrong or it's right?

I have read your doc file and the SetDefaultSlots function in Tdma-helper.cc ,but I couldn't understand what that algorithm's function .For example ,the Default slot array is below, I kown the first column respents the four nodes .What does other elements mean?  have tried to analyse the tr file but I can't find out how  time slot is assigned. Please help me ,thank you very much.
