Step 1.
Network Establishment: To establish the network each anchor node under its communication range supply its identification serial number, position, and hop count. The receivers (anchor and unknown nodes) update their routing table with the obtained information by adding one in the received hop count of the respective row of the routing table. A receiver may get this information repeatedly from other paths also. The receivers select the minimum hop count path by comparing the received values with the already available values in its routing table and also obtain the position of the anchor nodes.
