    • The method for forwarding data packets in position based routing of data from a source node (S) to at least one destination node (D) of a mesh network (1) comprises the following steps. A data packet (2) originating from the source node (S) is received at an intermediate node (A) and the geographical position of the destination node (D) is obtained from the data packet (2). All accessible neighbor nodes (Ci) of the intermediate node (A) and their positions are determined. For each neighbor node (Ci) of the intermediate node (A), a deviation value (vi) depending on the position of the neighbor node (Ci) in relation to a line of sight (4) between the intermediate node (A) and the destination node (D) is then determined and at least one of the neighbor nodes (Ci) is selected as a next intermediate node (B) depending on the determined deviation values (vi). The data packed (2) is then forwarded to the selected next intermediate node (B).
    • 用于将来自源节点(S)到数据网络(1)的至少一个目的地节点(D)的数据的基于位置的路由转发数据分组的方法包括以下步骤。 在中间节点(A)处接收源自源节点(S)的数据分组(2),并从数据分组(2)获得目的地节点(D)的地理位置。 确定中间节点(A)的所有可访问邻居节点(Ci)及其位置。 对于中间节点(A)的每个相邻节点(Ci),取决于相邻节点(Ci)相对于中间节点(A)和(A)之间的视线(4)的位置的偏差值(vi) 然后根据所确定的偏差值(vi)确定目的地节点(D),并且将相邻节点(Ci)中的至少一个选择为下一个中间节点(B)。 然后将打包的数据(2)转发到所选择的下一个中间节点(B)。
