Abstract
In infrastructure-less wireless networks, mobile nodes may communicate with each other directly without a central entity (base station) using half-duplex slotted ALOHA protocol. The traffic arrival rate to each receiving mobile node from its neighboring transmitting nodes is independent of the mobile nodes' density. The network traffic can be controlled very precisely from each mobile node. The stability of the system can be achieved without the knowledge of current network condition and we defined it as self-stability and the system as self-stabilized system. In this paper, throughput, packet rejection probability and self-stability with and without retransmission cut-off are studied in terms of five parameters. These five parameters are the new packet transmission probability of each mobile node, probability that a mobile node is in an idle mode, the receiving probability of each mobile node, capture ratio and the number of retransmission trials. Limiting the number of retransmission trials is not needed, if the new packet transmission probability of each mobile node is below a certain limit. The value of this critical limit is derived analytically. The results of this study may be used for a self-stabilized system design of an infrastructure-less contention-based multiple access schemes with and without capture and retransmission cut-off.
