Abstract
This thesis presents an analysis of the through put characteristics for several classes of Aloha
packet networks. Specifically, the throughput for variable packet length Aloha utilizing multiple power levels to induce receiver capture is derived. The results are extended to an
analysis of a selective-repeat Automatic Repeat Request (ARQ) Aloha network. Analytical
results are presented which indicate a significant increase in throughput for a variable
packet network implementing a random two power level capture scheme. Further research into the area of the near/far effect on Aloha networks is included. Improvements in throughput for mobile radio Aloha networks which are subject to the near/far effect are presented. Tactical Command, Control, and Communications (C3) systems of the future will rely heavily on Aloha ground mobile data networks. The incorporation of power capture and the near/far effect into future tactical networks will result in improved system analysis, design, and performance.
