Abstract: “In wireless sensor networks (WSNs), data aggregation techniques are used to collect the data sample at sink through the cluster head, generated by sensor nodes. Data aggregation for WSNs must address to the issues of WSNs like limited energy in battery powered sensor, and fast and efficient query response which is essential to network performance and maintenance. In this paper, we propose an Energy Efficient Activity scheduling algorithm which is reduces the state transition of cluster head. Dur”
