A Stochastic Game Analysis of the Slotted ALOHA Mechanism Combined with ZigZag Decoding and Transmission Cost.

This paper investigates the impact of transmission cost on stimulating the cooperation in decentralized Slotted ALOHA mechanism combined with ZigZag Decoding (SA-ZD). We model the system by a bi-dimensional Markov chain that integrates the effect of ZigZag Decoding (ZD), then we formulate the problem within a stochastic game framework. We evaluate and compare the performance parameters of our proposed approach with those of the same approach without transmission cost. We then show how to control the transmission cost to achieve the best performances. All found results show that our approach improves significantly the Quality of Service (QoS) of the system.
