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.

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.

Conclusion
They have studied the performance of EECA protocol relative to AODV under a group of network topologies and traffic scenarios. They
observed that EECA achieved better performance in energy conservation and data transfer efficiency in all cases.
