hi,

I don't quite understand some definitions used in ctp (I'm using tinyos-2).

-In CtpForwardingEngineP(), the generic module provides interface Send[uint8_t client]. What does this client integer refer to?

-[CtpForwardingEngineP] CLIENT_COUNT is the value of uniqueCount(UQ_CTP_CLIENT) [i am aware that uniqueCount counts the uses of unique], however, when I tracked back to Ctp.h, I found <#define UQ_CTP_CLIENT "CtpSenderC.CollectId"> . From here, I'm a bit lost as to what exactly CLIENT_COUNT refers to, 'coz when I checked CtpSenderC's interface, I couldn't make out the link with CtpSenderC.CollectId.

-[CtpForwardingEngineP] Am I right to say that a forwarded packet is one where the node is simply passing the packet to a destination such that it reaches the root eventually, whereas a packet from a send client is one where the node generates the data packet which is also to be sent to a destination such that it reaches the root eventually?

-[CtpForwardingEngineP, MViz] With reference to the MViz application, what is the difference between the interval found in MViz (default is 1024) with that of the FORWARD_PACKET_TIME which is effectively 4ms for a TelosB mote?

thanks..

azhar
