Abstract: To cope with the bursty traffic caused by popularity of multimedia services, the optimal base station density in heterogeneous networks by taking into account the burst characteristics of the traffic was analyzed using stochastic geometry approach. Based on bursty traffic, the traffic coverage probability of the heterogeneous network was defined and its relation with the base station density was specifically derived. An optimization problem with the aim of minimizing the base station density was formulated under the constraint of traffic coverage probability. Using binary search algorithm, the optimal base station density and the bounds (both upper and lower bound) for simplified analysis are obtained. Simulation confirms the accuracy of theoretical analysis and verifies the impact of the burst characteristics on the optimal base station density.

Key words: the optimal base station density, bursty traffic, traffic coverage probability, heterogeneous networks, stochastic geometry
