On a tandem queue with batch service and its applications in wireless sensor networks

We present a tandem network of queues 0 , ⋯ , s- 1. Customers arrive at queue 0 according to a Poisson process with rate λ. There are s independent batch service processes at exponential rates μ₀, ⋯ , μ_s _- ₁. Service process i, i= 0 , ⋯ , s- 1 , at rate μ_i is such that all customers of...

Data retrieval time for energy-harvesting wireless sensor networks

We consider an ad-hoc network of wireless sensors that harvest energy from the environment and broadcasts measurements independently, at random, provided sufficient energy is available. Clients arriving at the network are interested in retrieving measurements from an arbitrary set of sensors of some fixed size s. We show that the sensors...
