| 摘 要： | 针对大规模无线移动网络中节点对信道资源的群体性随机博弈问题,在载波侦听多路访问/冲突避免(CSMA/CA)的机制下,建立一种节点发包概率的演化博弈模型。考虑节点成功发送数据包的收益、监听、退避和冲突等成本因素,给出并证明该模型的演化稳定策略(ESS),推导节点发包概率演化的复制动态方程。数值仿真结果表明,该模型能提供更强的ESS,保证在多个移动节点干扰时演化稳定点的鲁棒性。

| Abstract: | Channel resource allocation between nodes in wireless mobile network is a random game problem of big population. An evolutionary game model is built, where the profit of success sending packet and the cost of overhearing/backoff/collision are considered. The Evolutionary Stable Strategy（ESS） is discussed and proved, and the replicator dynamics of MAC competition evolving is given. Numerical simulation result shows that the model can provide stronger evolutionary stable point concept ESS, it assures the robustness of evolutionary stable point between multi disturbing mobile nodes. |
