Energy Balanced Routing Method for In-Network Data Aggregation in Wireless Sensor Networks

摘要

A wireless sensor network (WSN) consists of a large number of wireless sensor nodes. Since wireless sensor nodes are battery powered devices, they have limited processing and transmission power. In order to transmit sensing data to receiver effectively, it is important to design a routing protocol for WSNs. Since energy conservation is a key issue in WSNs, data aggregation should be exploited in order to save energy. In this case, redundant data can be aggregated at intermediate nodes reducing the size and number of exchanged messages and, thus, decreasing communication costs and energy consumption. This paper propose an Enhanced Forward Aware Factor-Energy Balanced Routing Method (EFAF-EBRM) based on Data aggregation technique that has some key aspects such as a reduced number of messages for setting up a routing tree, maximized number of overlapping routes, high aggregation rate, and reliable data aggregation and transmission.. In the experiments, proposed method is compared with FAF-EBRM and LEACH. Experimental results show that proposed method outperforms FAF-EBRM and LEACH, which balances the energy consumption, prolongs the network function lifetimeand provides the best aggregation quality.
