We present a tandem network of queues $$0,\dots , s-1.$$ 0 , ⋯ , s - 1 . Customers arrive at queue 0 according to a Poisson process with rate $$\lambda $$ λ . There are s independent batch service processes at exponential rates $$\mu _0, \dots , \mu _{s-1}$$ μ 0 , ⋯ , μ s - 1 . Service process i, $$i=0, \dots , s-1$$ i = 0 , ⋯ , s - 1 , at rate $$\mu...
We consider the problem of retrieving a reliable estimate of an attribute from a wireless sensor network within a fixed time window and with minimum energy consumption for the sensors. The sensors are located in the plane according to some random spatial process. They perform energy harvesting and follow an asleep/awake cycle. A sink, at a random location in the plane, requests measurements from the...
We consider the problem of data estimation in a sensor wireless network where sensors transmit their observations according to decentralized and centralized transmission schedules. A data collector is interested in achieving a data estimation using several sensor observations such that the variance of the estimation is below a targeted threshold. We analyze the waiting time for a collector to receive...
