Energy efficient clustering algorithm for the mobility support in an IEEE 802.15.4 based wireless sensor network

The traditional clustering algorithm is an advanced routing protocol for enhancing an energy efficiency, which selects a cluster head and transmits the aggregated data arriving from the sensor nodes in the cluster to a gateway. However, the existing literature works were not suitable for an IEEE 802.15.4 beacon enabled mode and did not provide the combined solution for an energy efficient scheduling and handover of the sensor nodes. To address these problems, in this paper, we propose an energy efficient clustering algorithm for the mobility support in IEEE 802.15.4 networks. The simulation results show that the proposed scheme reduces the energy consumption and the packet loss, thus enhancing the performance.
