Know when to listen: SDN-based protocols for directed IoT networks

Low-power wireless networks are an integral part of the Internet of Things, composed of resource-constrained devices harvesting ambient information.<br/>The appearance of unidirectional links is characteristic of low power wireless networking due to physical effects, device heterogeneity and manufacturing imperfections.<br/>Despite the...

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...
