Location Algorithm for Nodes of Ship-Borne Wireless Sensor Networks

الملخص EN

Node location is of great significance as a supporting technology of wireless sensor network (WSN).

The information without position would be greatly devalued.

So this paper is about location algorithm for nodes of ship-borne WSN based on research on structure of ship and work environment of ship-borne WSN.

The whole location process consists of two steps: one is location algorithm among cabins (LAAC), and the other one is location algorithm in the cabin (LAIC).

LAAC refers to location with the topology of ship-borne WSN.

We can learn which cabin the node lies in.

LAIC refers to location based on received signal strength indication (RSSI), we can get distance relationship between nodes by RSSI, and then obtain the specific location by solving this distance relationship.

In the last part, this paper verifies the designed location algorithm by experimenting on “A” ship.

Experiments show that the location algorithm designed by this paper is feasible.
