Hey Everyone,

What does it mean if the processing time of a certain job instance is generated according to an exponential distribution with a certain mean? I already know the mean so what does it add to know its distribution and how can I use it?

Regards,

Hey All,

I have a camera sensor node that is periodically sampling the camera to detect activity. Then theses samples are first stored in the memory and then processed. My question is: do these sampled follow a certain probability distribution (Poisson, exponential, etc..) and what kind?

Any help is appreciated.

Hey Everyone,

I'm modeling a sensor node power consumed and lifetime using markov chain for two cases. Case 1: Assume that the node senses, processes and transmits the data. Energy and time spent in each state are considered random variables. I have no problems and I did my calculations for this case. It is similar to: http://thiagot.com/papers/jung_tosn09.pdf. Case 2: It is the simplest form and I need it for comparison reasons only. It assumes that only the sensor and the radio are awake and that the node sends whatever it senses. Does Markov Chain still hold to this case?

Thanks a lot in advance,
