Title MULTI-HIERARCHICAL CLUSTERING APPROACH FOR WIRELESS SENSOR NETWORKS
Keyword

  • Abstract In a wireless sensor network, sensor nodes are usually grouped into many clusters and a cluster head is responsible for sending the sensing data the base station. This thesis proposes an energy efficient clustering approach used in wireless sensor networks. We developed the simulation software to evaluate the performance of clustering approach. With more role rotations, our approach distributes the energy consumption evenly among all the sensor nodes and extends the usable life of the whole sensor network.
    Our performance evaluation differs from other researches in two aspects. First, our evaluation takes into account the energy consumed for the communication of control packets. Conventional researches on wireless sensor networks tend to neglect such energy consumption. We found that the amount of energy is too significant to be neglected. Second, the energy model we adopted is based on the measurement of the use of real devices. As energy saving is the main design target of clustering approaches, the simulation based on a practical energy model should provide more realistic results.
