Abstract: Survivability and channel allotting of Ad Hoc networks are solved based on put plane together and combining with emulator. The Ad Hoc network is built up with several circles with a radius of 100 units in an area of 1 000 × 1 000 units. The lapping efficiency corresponding to the intersection of 6 circles with inscribed regular hexagons is gained when the intersecting part is no less than 5%, thus all the region can be covered with 45 circles, and data can be exchanged by choosing 3 channels. And the lapping efficiency corresponding to the intersection of 4 circles with inscribed squares is gained when the intersecting part is no less than 18%, thus all the region can be covered with 64 circles, and data can be exchanged by choosing 2 channels. The experimental result indicates that the method can guide a variety of cellular mobile communication network.
