Area coverage based domain division in wireless sensor network

In wireless sensor networks (WSNs), extending networks lifetime is one of the fundamental and important issues. One of the ways is to choose the fewest number of sensors and maintains the coverage of domain. In this paper a new way of dividing domain into regular hexagon is presented, which is the dividing domain algorithms (DDA). And the simple procedure runs in a short time and the coverage sensor number is not larger than the procedure. At last, the simulation verifies the procedure is better than the other procedures.
