“…For example, wireless sensor networks (WSNs) are systems composed of devices distributed within a defined area based on specific application requirements. In these systems, devices must support wireless communication, computation, and sensing capabilities [ 1 , 2 , 3 ]. There are many possible environments where WSNs are deployed, and, in some cases, the number of nodes contending to transmit in the shared channel may be relatively low.…”

In this study, we analyze the CSMA Non-Persistent protocol with a finite number of nodes, providing more accurate results for applications like wireless sensor networks. The finite model addresses scenarios where the node count is moderate, capturing realistic system dynamics. Our analysis reveals a dependency on the node count, impacting system throughput. As the node count increases, throughput behavior aligns with Kleinrock’s infinite model. We derive a complex closed-form throughput expression for a finite quantity of nodes in the system, solved numerically, and offer an approximate expression for specific conditions. These insights advance understanding of low-contention network performance, especially in scenarios where the infinite model becomes inadequate.
