Embodiment 1
[0052] Embodiment 1 provides a method for determining a route. When N=1, the method is aimed at the first node in the network except the source node and the destination node; figure 2 is the flowchart of the route determination method, such as figure 2 As shown, the method includes:
[0053] Step 201: Determine a first neighbor node that is adjacent to the first node and can communicate with the first node according to a preset first transmission power, so as to determine a first path set from the source node to the destination node;
[0054] Step 202, when the first node is a node on a path in the first path set, adjust the first transmit power of the first node to a second transmit power, and the second transmit power ensures that the first node and its Satisfy predetermined communication requirements between neighbor nodes on the path;
[0055] Step 203, determining a second neighbor node that is adjacent to the first node and can communicate with the first node accordi...
Embodiment 2
[0077] Embodiment 2 provides a method for determining a route. When N=1, the method is aimed at control nodes (including source nodes, destination nodes, controllers or sink nodes) in the network; Figure 4 is the flowchart of the route determination method, such as Figure 4 As shown, the method includes:
[0078] Step 401, receiving a first neighbor node reported by each first node in the network;
[0079] Step 402, according to the received first neighbor node, determine a first path set from the source node to the destination node;
[0080] Step 403, receiving the report of each first node on each path in the first path set, according to the second neighbor node of the first node and the second neighbor node except the second neighbor node of the first node on the path a first interference coefficient of each first node determined by other second neighbor nodes;
[0081] Step 404: Calculate the second interference coefficient of each path in the first path set according...
Embodiment 3
[0089] Embodiment 3 provides a method for determining a route, Figure 5 is a flow chart of the routing determination method, combined below Figure 5 Explain how to determine the first path, such as Figure 5 As shown, the method includes:
[0090] Step 501, the first node in the network determines a first neighbor node that is adjacent to the first node and can communicate with according to a preset first transmission power;
[0091] Step 502, the first node in the network reports its own first neighbor node to the control node; the control node may be a source node, a destination node, a controller or a sink node;
[0092] Step 503, the control node receives the reported first neighbor node, and determines a first path set from the source node to the destination node;
[0093] Step 504, the control node notifies the first node in the first path set to perform step 505;
[0094] Step 505, adjusting the first transmit power of the first node to a second transmit power, th...
