The Comparison of Energy Consumption of Different Topologies in Multi-hop Wireless Sensor Networks

The Wireless Sensor Networks (WSNs) consists of sensor nodes (SNs) that are distributed randomly or preplanned form and have restricted capacity. Because SNs are energy limited and battery change is difficult, energy consumption is one of the most vital factors affecting the WSN design. There is a lot of energy efficiency studies done because of the effect on network life time. In a multi-hop connection model, nodes that are out of range of base station (BS) communicate with BS through other nodes. For this reason, the packet traffic of SNs that close to the BS the increases. Along with this packet traffic increase, extreme energy consumption occurs its. Due to run out of the energy of the node, the node is disconnected from the network. The preferred topologies and protocols in multi-hop WSNs have a significant impact on energy consumption. In this study, the effect of different WSN topologies on energy consumption under the same conditions was examined comparatively. For this purpose, a multi-hop WSN application was made in different scenarios in the simulation environment and the total energy consumption amounts of SNs were scrutinized for different topologies.
