In this paper, we propose an energy efficient MAC protocol for wireless sensor networks. Since sensor nodes are equipped with a limited energy of batteries, reducing energy consumption is a critical issue for extending network lifetime. To resolve this issue, we adopt a listen-sleep cycle as in S-MAC, allowing sensor nodes to turn their transceiver off during a sleep period. In S-MAC, sensor nodes have a fixed duty cycle and a synchronized scheduling in a virtual cluster. Hence, in S-MAC, it is… CONTINUE READING
