Abstract :
The performance characteristics of multihop homogeneous S-Aloha-type packet radio networks are investigated. Special attention is paid to the second-layer station protocols that include channel access, an acknowledgment (ACK) scheme, and buffer management. An analytic queuing network model which assumes limited queue dependency is developed. Multiple copies of global ACKs piggybacked to data packets and a window mechanism for transmission control purposes are accepted. The influence of the window size on the station throughput and the average packet delay is investigated. The theoretical network performance parameters are obtained by the steady-state analysis of station buffers. The simulation results are evaluated using a regenerative simulation method
