Figure 9(a) is a 3D surface for node number, communication path distance, and network lifetime in wireless sensor networks.
The coal mine robot wireless sensor network node energy can be utilized effectively.
In the first phase, a random witness chain for a node is generated by the node sending its encrypted private information including ID and location to the witness nodes.
In the second phase, a detection route for the node is established in a ring that is randomly selected from the nonhotspot area, and the route is formulated along the ring, that is, in the circumferential direction.
Each node initializes NL and hop count, the initial value of hop count is 0.
[X.sub.N] represent the nodes. After the flooding process, the CVR of [X.sub.i] to a certain node is set to 1 if this node can communicate with [X.sub.i].
