摘要： An object of the invention is to obtain a high-speed and high-accuracy radio-wave propagation characteristic forecasting system in combination with the launching method by correctly estimating a diffraction phenomenon when a ray passes the vicinity of an edge of a structure. To estimate a radio-wave propagation characteristic in accordance with the ray launching method, when a ray passes the vicinity of an edge of a structure, a diffracted wave is generated at the edge if the distance between the edge and the ray is smaller than the radius of a ray spread. Thereby, it is easy to combine the ray launching method with the conventional ray launching method and it is possible to estimate a high-speed high-accuracy radio-wave propagation characteristic also considering a ray diffracted wave.

摘要： To shorten a required estimation time while keeping an estimation precision in an object environment given for estimating propagation characteristics with a ray launching method. In the case where a ray is propagated within a given observation area, and collides with a barrier residing on its path, a space in the vicinity of the ray is divided into a plurality of partial spaces until a predetermined condition is satisfied. The space in the vicinity of the ray that is considered to cause a degradation in the estimation precision is divided in reflection until there is less influence of degradation, whereby each of the subdivided partial spaces can be handled individually, so that the estimation precision of radio wave propagation characteristics can be made better than a conventional method. On the other hand, in the case where there is possibly less influence of degradation in the estimation precision, the space is not divided, whereby if a ray is radiated from a transmitting antenna coarsely, the total number of rays is reduced below that of the conventional method, so that a total calculation time taken for a propagation estimation can be shortened.
摘要翻译：缩短所需的估计时间，同时在通过射线发射方法估计传播特性的对象环境中保持估计精度。在射线在给定的观察区域内传播并且与其路径上的障碍物相撞的情况下，射线附近的空间被分成多个部分空间，直到满足预定条件。认为导致估计精度降低的光线附近的空间被反射分割，直到降级的影响较小，从而可以单独处理每个细分的部分空间，使得无线电的估计精度波传播特性可以比常规方法更好。另一方面，在估计精度的劣化影响可能较小的情况下，不分割空间，如果从发射天线粗略地辐射射线，则将光线总数降低到低于可以缩短传播估计所需的总计算时间。

摘要： An object of the present invention is to provide a method for detecting a shield in predicting the radio wave propagation characteristics by a technique of the geometrical optics capable of detecting a content which a ray strikes, at high rate, when the ray is radiated within the observation space. In the case where the rays and the contents are given, the projected objects given by the line or plane are set up, and if an image of the content projected onto the projected object and an image of the ray projected onto the projected object do not intersect, the content is excluded from the shield detection object. A plurality of projected objects i (i=1 to M) are prepared, the selection of shield detection object is performed for each projected object i in order for i=1 to M, and the content of the shield detection object is concluded in sequence. Though the conventional method required the multiple variable equations to be solved for all the contents within the observation area, this invention allows the multiple variable equations to be solved only for the concluded contents of the shield detection object. Hence, the processing time can be shortened.

摘要： Provided are a communication system and the like capable of making a stable relay route even when a propagation channel is fluctuated by the fluctuation of RSSI. For making a tree-type communication route whose root is a core node, each slave node, after the reception of the latest reset routing packet from a node, judges if the transmission source node should be the parent of the tree-type structure based on the sequential average of the reception power of n routing packets received from the same transmission source node. As the reception power is log-normally distributed in general, an asymptotically stable relay route can be obtained, especially by using the sequential average.
