Semi Markov Model for sensor nodes

[SarahLi]

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,

Does Markov Chain still hold to this case?

You should be able to answer this by looking up the definition of what constitutes a Markov Chain, paying particular attention to past, present, and future state dependence and independence.
