Synchronization is crucial to wireless sensor networks. Recently a pulse-coupled synchronization strategy that emulates biological pulse-coupled agents has been used to achieve this goal. We propose to optimize the phase response function such that synchronization rate is maximized. Since the synchronization rate is increased independently of transmission power, energy consumption is reduced, hence extending the life of battery-powered sensor networks. Comparison with existing phase response functions confirms the effectiveness of the method.
同步对于无线传感器网络至关重要。最近,一种模拟生物脉冲耦合主体的脉冲耦合同步策略已被用于实现这一目标。我们建议优化相位响应函数,以使同步速率最大化。由于同步速率的提高与发射功率无关,因此降低了能耗,从而延长了电池供电传感器网络的寿命。与现有相位响应函数的比较证实了该方法的有效性。
