  4. Assumption • The sensor network consists of N nodes deployed randomly with uniform distribution. • Each node can adjust radio transmit power to vary its communication range from 0 to the maximum transmit range, denoted as R. • We assume that each node knows its position. • Additionally, we assume that each node knows the position of the destination node.

  5. Protocol • Route Request • 1) all those nodes are closer to the destination. • 2) nodes in each group lay at one side of the source-destination line. • 3) each node is distanced more than R/2 from the source destination line.

  15. Simulation • NS-2.33 simulator • 1000 m by 1000 m area • 100 static nodes deployed uniformly randomly • maximum transmit range 250M • The power drained for each transmission is 1.6 W. • The power drained for reception is 1.2 W. • All packets are of the same size of 512 bytes.
