Distributed region-based monitoring in low-power listening wireless sensor networks
Krita Pattamasiriwat, Chaiporn Jaikaeo
Abstract Download PDFAdvancement in IoT technology and the concept of Information-Centric Networking lead to less importance of node individuality since several nodes can work interchangeably. Multiple sensor nodes can be grouped into a region and monitored as one instance to guarantee su°cient coverage over the region. Therefore, a single node fault often does not need to be reported unless it is the last node in the region. In addition, applications focusing on detecting rare events rarely require nodes to transmit and often rely on a low-power listening MAC protocols, where nodes spend most of their time sleeping but require signi˝cantly more work during transmission. In such situations it is desirable to avoid periodic status reports transmitted to the central monitor station as usually found in a centralized monitoring scheme. A distributed region-based monitoring scheme, or DRMON, is then proposed to facilitate this circumstance. This approach designates a representative to each region so that it can be used as an indicator of the region"es status with a mechanism to re-elect a new representative until all nodes in the respective region are dead, implying region inactiveness. We evaluate the suitability of DRMON over various scenarios in two aspects: centralized vs. distributed monitoring schemes and individual-based vs. region-based monitoring schemes, along with existing work in the literature.
