Data Latency in Time Multiplexed Bus Systems for Missile Applications.

Abstract

This research examines the performances of three computer communication bus protocols: round robin passing protocol (RRPP), modified round robin passing protocol (MRRPP), and carrier-sense multiple-access with collision detection (CSMA/CD). These are compared through the simulation of a medium-range air-to-surface guided weapon federated computer network, specifically the mid-course guidance phase. The performance of each protocol is measured by the average and maximum message waiting time and latency. Under these performance measures, the CSMA/CD protocol is clearly superior, with average message waiting time as low as 22% of that for RRPP and 8% of that for MRRPP. Maximum waiting times are also lower for CSMA/CD, although by a much narrower margin. This indicates the potential for the use of CSMA/CD communication channels in low channel utilization, delay-sensitive applications. (Author)
