摘要: 针对传感器网络的覆盖问题,提出一种资源约束的传感器网络信息覆盖分析方法。该方法考虑传感器网络能量和带宽有限的特点,采用分布式估计机制对簇头节点收到的量化离散消息进行最终估计。实验结果表明,该模型与理想条件下的信息覆盖模型相比能更真实、准确地反映实际应用中资源约束传感器网络的覆盖质量。

Abstract: Aiming at the coverage problem in sensor networks, this paper proposes an analysis approach of resource-constrained information coverage. Considering the energy and bandwidth constraints in sensor networks, it introduces a universal decentralized estimation scheme to make final estimation of quantized discrete messages aggregated by a leader node. Experimental results show that this approach has more realistic and accurate estimation for coverage performance than the one under ideal condition in a practical sensor network.

Key words: resource-constrained, information coverage, sensor networks, coverage
