Energy efficient information dissemination scheme based on the received signal strength in wireless sensor networks

In this report, we propose an information dissemination scheme to facilitate electric power consumption for wireless sensor networks. Our new dissemination scheme is based on the flooding and uses the receiver signal strength for determining the broadcast timing. We evaluated our proposed scheme by simulations. We used a network model where sensor nodes are arranged on the square lattices. As a result, it is shown that our proposed scheme improves the information delivery ratio by increasing the power consumption slightly in the network. Furthermore, we ran simulations using a network model where sensor nodes are randomly located and showed that the proposed scheme had the same characteristics as simulation results using the network model, where sensor nodes are arranged on the square lattices.
