| Summary: | The sensors (nodes) in sensor networks have limited energy and thus energy-preserving techniques are important. Throughout this study, there are three routing protocol being tested to get the best routing protocol in improving energy consumption. The routing protocol uses are Direct Communication (DC), Minimum Transmission Energy (MTE) and Low Energy Adaptive Clustering Hierarchy (LEACH). DC is more towards direct communication while MTE is multi hop communication whereas LEACH constructs cluster base on radio range and the number of cluster members. LEACH technique improves energy efficiency of the sensor network by selecting a cluster head, and having it aggregate data from other nodes in its cluster and transmit it to the base station. LEACH uses randomized rotation of the cluster-heads to evenly distribute the energy load among the sensor nodes in a network. From simulation, it shows that LEACH is the most energy efficient routing protocol compared to DC and MTE. |
