Segmentation of telemetry frames during message packing in wireless sensor networks

Abstract

A model for evaluating wireless communication channel capacity with the noiseless coding of messages in the case of repeated transfer of damaged information packets is proposed. The optimum values of the information packet characteristics are calculated according to various ratios of the signal energy parameters and interference in the channels. An algorithm of telemetry frame segmentation into subframes is presented. The number of elements in the subframes is maximal approximated to the number of information elements in packets of optimal length. Here the multiplicity condition of telemetry frame length is considered in relation to the number of subframe elements. It is very important in a case of cyclic interrogation for measuring sensors.
