Energy-Balanced Transmission With Accurate Distances for Strip-Based Wireless Sensor Networks

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.
