A channel allocation algorithm with low admission delay for mobile base station networks

In this paper, a channel allocation algorithm is proposed with low admission delay. It is designed for mobile based networks in which fixed base stations are replaced by mobile base stations(MBSs) placed on moving vehicles. Considering the high dynamic characteristic of MBSs network, the channel admission delay is a critical indicator. In order to minimize the admission delay of each MBSs fairly, an min-max optimization model for reserve channel number of each MBS is constructed. Also, the Particle Swarm Optimization(PSO) algorithm is adopted to solve the problem due to its low complexity which is crucial in mobile scenario. Finally, we evaluate the performances of proposed algorithm by simulation. Compared with former algorithm, the proposed algorithm can effectively reduce the admission delay and maintain fairness.
