Access control research based on evolutionary game theory in slotted-Aloha network
时隙Aloha网络中基于演化博弈论的接入控制研究*

Considering the problems of the noncooperation system behavior of slotted-Aloha network,the existing instable areas and the bandwidth-limited of network,this paper established an access control model of slotted-Aloha network which was based on evolutionary game theory,then proposed ABEGT protocol.Under considering bounded rationality of users,ABEGT protocol ensured the stability of the system and improved throughputs of the network.Meanwhile,it proved that there was an evolutionarily stable strategy in the slotted-Aloha network.Finally,by using MATLAB,the results indicate that ABEGT protocol not only reduces the users’ interference,but also improves the utilization ratio of network resources and the stability of the whole network.
