摘要
为了解决D2D资源分配算法的能耗控制与系统中断问题,提出一种引入模拟退火的动态穷举D2D资源分配算法。该算法使用动态间隔的穷举搜索算法初步确定用户发射功率,制定包含用户QoS信息的二维复用表,联合蜂窝用户与D2D用户的QoS以确定复用组合,在功率维度加入调整功率模块,在组合维度引入模拟退火算法联合降低中断概率。仿真结果表明,引入模拟退火的动态穷举资源分配算法相比于传统算法,在功率分配阶段功率均值平均降低了78.3%,在信道分配阶段连通概率平均提高了10.2%,计算时间平均减少了10.1%。
In order to solve the problem of energy consumption control and system outage of D2D resource allocation algorithm,a dynamic exhaustive D2D resource allocation algorithm with simulated annealing is proposed. The algorithm uses a dynamic interval exhaustive search algorithm to initially determine the user transmit power,and creates a two-dimensional multiplex table containing user QoS information. Then the algorithm combines the QoS of the cellular user with the D2D user to determine the multiplexing combination,adds an adjustment power module in the power dimension and introduces a simulated annealing algorithm in the combined dimension to reduce the outage probability. The simulation results show that,compared with the traditional algorithms,the dynamic exhaustive resource allocation algorithm with simulated annealing decreases the average power by 78.3% during the power allocation phase,increases the probability of connectivity in the channel allocation phase by 10.2% on average,and reduces the calculation time by 10.1% on average.
