Embodiment Construction

[0045] The embodiments of the present invention will be further described in detail in conjunction with the above-mentioned drawings.

[0046] Such as figure 1, the implementation of the present invention first proposes a vehicle path avoidance method to find a shortest path from the source node to the destination node with low energy consumption. Then, through the node clustering method, nodes with high residual energy are selected to form a network to form an efficient communication backbone network to effectively extend the lifetime of the network. Finally, the shortest path problem of message transmission is solved by vehicle path avoidance.

[0047] Specific implementation steps:

[0048] Step 101: construct a random wireless sensor network;

[0049] Step 102: use the node clustering method to determine the cluster head node, and then establish a backbone data transmission network based on the cluster head node;

[0050] Step 103: Randomly select entrances and exits, s...

Abstract

The invention discloses a wireless sensor network data transmission method based on pilotless vehicle monitoring. A pilotless vehicle provided with sensor nodes enters into an area covered by a sensor network from a certain entrance to an exit. The method comprises the following steps of: firstly, performing node clustering networking to form an efficient communication backbone network; then, finding a shortest path with low energy consumption from a source node to a destination node for the pilotless vehicle, and simultaneously determining the shortest path of monitoring message transmission; and collecting monitoring messages by the vehicle while passing through the path, and returning the monitoring messages to a base station by the wireless sensor network. The invention realizes dynamic monitoring on a pilotless dangerous environment, and better solves the problem that the netwrok life cycle is shortened because a certain nodes are frequently used for transmitting data during datatransmission to cause unbalanced node energy in the network and thus the excessively used nodes die too early by forming the backbone network by residual nodes with high energy.
