Wireless sensor networks (WSNs) are composed of sensors exchanging the information that they collect from the environment. The use of a scheduler offers an efficient solution to eliminate information redundancy and possible collisions in this network. A scheduler is responsible for choosing the sensors to exchange information at each step of the algorithm's execution. This article presents a WSN handshake algorithm (WSN-HS) scheduling the communications between every two sensors safely in an exclusive mode. Our WSN-HS is energy-efficient. It tries to elaborate communications between sensors with the minimum of messages and thus with the minimum of energy consumption. In addition, our algorithm is fault-tolerant to sensors' disappearance. Hence, when a sensor runs out of energy, the other sensors in the network will not be blocked and they will continue executing the distributed algorithm. We compare and evaluate our algorithm with another handshake algorithm. The results of the simulation done with two examples of distributed algorithms show that our algorithm significantly minimizes the energy consumption in the WSN. Moreover, in this article, we detail the analysis that emphasizes the efficiency of our WSN-HS algorithm.

无线传感器网络中调度通信的握手算法

无线传感器网络 (WSN) 由交换从环境中收集的信息的传感器组成。调度器的使用提供了一种有效的解决方案来消除该网络中的信息冗余和可能的冲突。调度程序负责选择传感器以在算法执行的每个步骤交换信息。本文介绍了一种 WSN 握手算法 (WSN-HS)，以独占模式安全地调度每两个传感器之间的通信。我们的 WSN-HS 是节能的。它试图用最少的消息来详细说明传感器之间的通信，从而用最少的能量消耗。此外，我们的算法对传感器的消失具有容错性。因此，当传感器耗尽能量时，网络中的其他传感器不会被阻塞，它们将继续执行分布式算法。我们将我们的算法与另一种握手算法进行比较和评估。用两个分布式算法示例完成的模拟结果表明，我们的算法显着降低了 WSN 中的能耗。此外，在本文中，我们详细分析了强调 WSN-HS 算法效率的分析。
