摘要
由于网络通信信息量庞大,在传输过程中容易造成网络拥堵,导致用户信息传输效率偏低。对无线网络用户通信信息传输分流问题的研究,能够有效改善网络拥堵现象,充分提高用户通信效率。对通信信息的分流,需要计算节点之间发送信息量,计算在数据收集周期内节点的总能耗,完成信息精准分流。传统方法先建立网络能量消耗模型,以最小能量消耗为目标进行分流,但忽略了得到节点的总能耗量,导致分流精度偏低。提出基于链路调制的无线网络用户通信信息精准分流方法,计算节点之间发送信息量,降低数据丢失概率,计算节点在数据收集周期内的总能耗,根据能耗结果实现通信信息分流,提高无线网络带宽的利用效率。实验结果表明,所提分流方法使用后,通信信息中含有的噪声较少,丢包率和流破坏率较低,保证了通信信息的效率,对无线网络快速安全运行具有促进意义。
This paper proposed a method for precisely shunting communicated information of user in wireless network based on link modulation. In this method, the information amount between nodes was calculated to reduce the probability of data loss. Then, the total energy consumption of nodes in the period of data collection is calculated. According to the result of energy consumption, the distributary of information communication was realized and the utilization efficiency of wireless network bandwidth was improved. Simulation results show that, after using proposed method, the communication information has less noise. The packet loss rate and flow failure rate are low. The efficiency of information communication is guaranteed. The method has significance to promote rapid and safe operation of wireless network.
