Abstract: Data packets generated by sensor nodes are generally routed and transferred to a sink node or a gateway in IoT (Internet of Things) environments. So many data packets may be driven into small number of nodes, resulting in significant packet collisions, severe latency, and unnecessary energy consumption of the sensor nodes. In this paper, we proposed an intelligent data collection MAC protocol (IDC-MAC). The basic idea of this mechanism is to reduce duplicated data packets before they are sent to their neighbor nodes and to save node’s unnecessary energy consumption. In IDC-MAC protocol, a node uses data signal length, data receiving direction, and its residual energy to determine whether the node itself participates in the data transmission. Using this MAC protocol, the node energy consumption can be reduced, and the entire network lifetime can be extended. Our results show performance improvements up to 21.6% in network lifetime and 23% in node energy consumption compared with related protocols. |
Keywords and phrases: Internet of Things, MAC protocol, residual energy, wireless sensor networks.
