An obvious limitation of wireless sensor networks (WSNs) concerns the energy consumption and the network lifetime. Transmitting signals, including sending and receiving, take most of the energy dissipation in such a network. Generally the data transmission in such a network follows a many-to-one pattern, which leads to the so-called energy hole near the sink and lifetime reduction. This paper makes a first attempt to solve the many-to-one transmission problem of strip-based WSN and avoid energy holes of such a network, which is divided into multiple layers. Specifically, we propose an accurate-distances based transmission scheme, which aims at achieving the most precise layer lengths so far and obtaining the optimal transmission distances in different regions to date. Such a transmission scheme enables the network lifetime of the strip-based WSN to reach a maximum. Extensive simulations are carried out to validate the effectiveness and advantages of our transmission scheme.
