摘要

Energy efficiency of wireless sensors is critical to maintaining the function of the monitoring system. Generally, the energy consumed in data transmission is much larger than in compression. Hence, decreasing data packet size with the aid of data compression before transmission can facilitate the reduction of energy consumption in communication. However, the energy consumed in data computation is also considerable, and improper computation ways may incur more energy consumption. To address this issue, in this article, two-hierarchy communication and computation hybrid optimization protocol is presented to minimize the total energy consumption. First, the cluster heads (CHs) rotation and clusters updating strategies are proposed in the communication layer, and the optimized adaptive compression ratios for the CHs are adopted in the computation layer. The hybrid optimization scheme is performed from the views of communication and computation synergistically to improve energy efficiency. The simulation results show the superiority of the proposed protocol compared with other outstanding protocols
