Analysis of Frame Length and Frame Error Rate For the Lowest Energy Dissipation in Wireless Sensor Networks

Abstract

Energy dissipation is focused in energy constraint communication systems such as in wireless sensor networks, which depends on both channel conditions and communication protocols. Assuming in stop-and-wait ARQ (automatic request for repeat) protocols on Rayleigh fading channel, in this paper, we derive eqs. (1) to (5) and then establish a model of transmission energy dissipation for per payload bit. By computer simulation, we obtain Fig. 1, Fig. 2 and Fig. 3. Results in these Figs, show that, for specified frame header length and frame error rates (FER), there exists the optimal frame length for the lowest energy dissipation and then this optimal frame length is determined if the payload length is equaled to the frame header length in bits. On the other hand, for given optimal frame lengths, there exist the optimal frame error rate for the lowest energy dissipation although it is approximately 0.65. Furthermore, both the optimal frame length and the optimal frame error rate are not related to each other.
