Abstract: In the field concerning the wireless sensor network, the constraint of energy dissipation plays a very crucial role in determining the overall performance efficiency of the system. The main consideration criterion for any wireless network is the topology of that network. The topology considered in the proposed work is the CATree topology which uses Kmap technique to reduce the distance map between the nodes. A comparative analysis is performed considering different topology such as star topology and mesh topology with respect to CAtree topology. The evaluations of the proposed system is performed with respect to network throughput, packet delivery ratio and energy dissipation.
