Abstract :
We models the contention access as an N-person non- cooperative game firstly, then the game is transformed into a constrained optimization problem, each node in the network chooses the optimal probability to maximize its utility function, finally an algorithm is presented for solving the Nash equilibrium. Through simulation and comparison, the contention access game method can reduce the collision probability and improve the system throughput.
