摘要:

密度控制是一种常用的提高大规模无线传感器网络生命周期的方法,目前的密度控制算法大多基于0~1覆盖模型,而在实际的应用环境中概率覆盖模型能够更准确地定义网络覆盖能力. 所提出的一种基于概率覆盖模型的密度控制算法,能够在保证足够的网络覆盖能力的前提下,关闭掉冗余节点,减少网络的总能量消耗.

Abstract:

Density control is the common way to improve the network lifetime of large scale wireless sensor network. Many density control algorithms are based on 0~1 coverage model, whereas probability coverage model defines network coverage ability more accurately than 0~1 coverage model in real applications. A density control algorithm based on probability coverage model was presented, which can turn offredundant sensor nodes to reduce total network energy consumption and ensure adequate network coverage ability.

Key words: wireless sensor networks, density control, probability coverage model, coverage probability
