In TSA instead, for each collision slot s, a new child frame with a smaller slot number is issued. And only the tag that decided to transmit in slot s will transmit in the same frame.
|

The TSA protocol improves the system efficiency as the probability of having a collision is lower. But for both protocols, to have good performance is important to have an estimate of the number of tags to identify as we need to chose the number of slots based on it. If we have too many slots, we will have a lot of time wasted in idle slots, if we have too few slots, we will have a lot of collisions.

#### Q: in a slotted aloha protocol for RFID system how is estimated the tag population participating into intermediate frames?

Main issues:
|
||||
- total number of tags to identify is not known
|
||||
- initial frame size is set to a predefined value (e.g. 128)
