Analysis of energy consumption in Heterogeneous Sensor Networks with Mobile Sink

Wireless sensor networks are energy constraint battery powered sensing, computing and communication infrastructure. Sensor nodes are randomly deployed and organized as clusters, and each node is responsible for transmitting the data to its cluster head. Most of the existing sensor networks focus on homogeneous in which the cluster heads are changed periodically. In order to reduce power consumption of Sensor Networks, we have investigated Load Balanced Heterogeneous Sensor networks with Adaptive Transmission Power Control (ATPC), and mobile sink. The simulation results show that the consumed energy is less in the case of ATPC and Mobile Sink (MS) when compared to stationary sink.
