Abstract
To improve the transmission throughput, this paper investigates the problem of the optimization of stochastic access probability for delay-sensitive applications in wireless ad hoc networks. Specifically, the transmission throughput is first defined and adopted as the performance metric to evaluate the network performance. The closded expression of the successful transmission probability is derived based on stochastic geometry. Then, the queueing delay including the waiting and transmission delay is also achieved through modelling the queueing process as M/M/1 model. After that, the problem of maximizing the network transmission throughput is formulated into an optimization problem under the delay constraints. To solve it, the closed-form expression of the optimal stochastic access probability is derived. Numerical results demonstrate the proposed optimal stochastic access scheme can improve the transmission throughput performance through comparison with two existing schemes.
