中文摘要：
研究森林火灾监测问题时，因客观地理条件和环境的特殊性，无线传感器网络节点在部署时具有一定的局限性。为在平衡能耗的前提下提高无线传感网络的监测质量，根据目标区域的火险等级采用或构建不同的无线传感器网络模型，即在低火险区位采用动态布局优化策略提高感知覆盖率、高火险区位采用拼接覆盖模型提高监测质量，以提高无线传感器网络的整体工作性能。实验结果表明，优化后的无线传感器节点部署策略能有效提高传感器网络对森林火险的整体监测质量。
英文摘要：
In the forest fire monitoring, because of objective geographic and special environment conditions, deploying sensor network nodes is full of difficulty and limitations. Under the premise of balancing the covering energy consumption, improving the monitor quality of the wireless sensor network is the target of this study. Based on the risk level of fires in target area, this paper adopted or built different wireless sensor network models, namely in the low fire location using dynamic layout optimization strategy to improve sensing coverage and in high fire location using splicing coverage model to improve the quality of monitoring in order to improve the wireless sensor network as a whole performance. Experimental resuhs show that the optimized sensor nodes deployment strategies can effectively improve the overall monitoring quality of sensor network.
