Dear All, A slight digression from the ongoing ML discussions. Hope the timing is OK!
As we all know, transmit power control is one of the powerful knobs that can be used to minimize the interference and thereby improve the wireless network performance and also provide deterministic network. Cell breathing technique used in WLANs comes to our mind. When it comes to 6tisch, one might argue that with 16 channels at our disposal, the interference can be avoided through smart 6top cell management interface without worrying much about transmit power control. However, there can be scenarios where transmit power control might be required, for instance, (i) large scale dense deployments with heavy traffic demands (ii) Co-existing WiFi reducing available non-overlapping channels for 15.4 (iii) prevent wireless leaks beyond the periphery of the deployement region and (iv) OTF scheduling where nodes make local decisions for managing cells, may be more. One possibility is to leave the power management to the nodes. We are then leaving this to implementors to device their own algorithms to handle interference. Alternatively, a centralised controller (NME) knowing the information about conflicting links can adaptively and optimally adjust the operating transmit power of the nodes to avoid the interference and maximize the wireless network performance. If we treat transmit power as one of the controllable parameters along with the cell management parameters, wondering if 6tisch 6top interface MIB is the place to define this. Or this parameter is beyond the scope of 6tisch. Any suggestions ?
