Abstract :
An analysis of the throughput for two variable-packet ALOHA network models is presented. Variable-packet ALOHA does not require (1) padded bits to fill up a packet to its specified length (which may significantly reduce the throughput of fixed-packet ALOHA), or (2) bit stuffing and destuffing logics (which increase equipment cost in fixed-packet ALOHA). The first model uses random two power levels to induce receiver capture. The second model considers the near/far effect between users and the base station in a local or mobile radio networkl. Analytical results that indicate a significant increase in throughput for both models are presented
