[Tinyos-help] BaseStationP trasparent bridging problem

Hi all, in SerialActiveMessageP there is a note in the AMSend.send command: "Do not set the source address or group, as doing so prevents transparent bridging" I think this is correct, but the same don't happen in the send command of ActiveMessageC: in the micaz implementation, in CC2420csmaP,

[Tinyos-help] Acknowledge frames may be manually transmitted

Hi all, at page 42 of CC2420 datasheet (http://focus.ti.com/lit/ds/symlink/cc2420.pdf) there is: "Acknowledge frames may be manually transmitted using normal data transmission if desired." What this mean? I have a sensor sending messages to a basestation/host. I would send an ack (from basestat

[Tinyos-help] reproduce the radio environment

Hi all, how can I get the gain values for the link between 2 nodes (CC2420) to reproduce a radio environment in Tossim2 (CPM model)? I have thought this "plan": Supposing I have two motes, - measure the noise N1 and N2 (e.g. with RssiToSerial); - measure the RSSI's packets for both nodes, Str1 a

[Tinyos-help] Collection trees for bi-directional communication

Hi all, I would make a multihop ping application using Collection components. Supposing that I have a 3 motes linear configuration ( BaseSt -- 1 -- 2 ), how I could make 2 different trees (one rooted at the base station and one at the node 2)? Should I set both nodes as "root" (using only one C

[Tinyos-help] adding tossim-event from outside

Hi all, I have modified tossim and now the simulation time is the same of the actual time. I would add receive-event in tossim from an external application whithout delaying the simulation too much. I think I have 2 options: 1) use UDP/server with signal-driven I/O (because with UDP a signal is

[Tinyos-help] UscGainInterferenceModelC implementation

Hi all, relating to the "sim_gain_receive_handle" function (UscGainInterferenceModelC.nc file), I don't understand when the code that checks if has been received a packet stronger than the others, i.e. "if ((list->power - sim_gain_sensitivity()) < heardSignal())" could be false (heardSignal()
