Abstract:

This paper considers the use of low-complexity diversity combining hybrid ARQ schemes (Automatic Repeat reQuest) on a TDMA (Time Division Multiple Access) system. Its low complexity makes it particularly interesting for battery-powered nodes of a wireless sensor network (WSN). TDMA is commonly used for WSNs applications that require high throughput or constrained packet delay. This paper analyzes the energy per useful packet, packet delay and goodput performances of the TDMA system. Analytical models were used to define a constrained energy optimization problem, where the minimum transmission power is calculated based on the goodput and delay constraints. Analytical results were validated through simulations.
