【摘要】：提出基于社区的最优能效路由策略,在给定的延时约束下最小化网络能耗。首先利用马尔可夫链获取信息在连通网中传递的期望能耗和期望延时,然后构建信息从源节点传递到目的节点的能耗和延时综合成本函数,以及中继节点传递信息对综合成本的优化函数,从而得到中继节点的报酬函数,最后利用最优停止理论获得最优中继节点的最优期望报酬,实现最优能效路由策略。在仿真实验中,将提出的路由优化策略与相关文献的路由策略在平均能耗、平均延时和平均传递率各指标上进行对比,结果表明所提的路由策略具有较小的平均能耗、较低的平均延时和较高的平均传递率,取得较好的能耗优化效果。
[Abstract]:The optimal routing strategy based on community, in a given delay constraint to minimize the energy consumption of the network. Firstly, using the Markov chain to obtain expected consumption and expected delay of information transmission in network connectivity, and then construct the transfer of information from the source node to the energy consumption and delay cost function of the destination node, relay node and transfer function of comprehensive cost optimization the information, so as to obtain the reward function of the relay nodes, the optimal expected return by using optimal stopping theory to obtain the optimal relay node, realize the optimal routing strategy. In the simulation, the proposed routing optimization strategy with the routing strategy on average consumption rate of each index were compared, and the average transfer delay the result shows that the average energy consumption, the proposed routing strategy has a smaller average transfer rate, average delay and high low, made Better energy consumption optimization effect.
