Proceedings ArticleDOI
Low energy adaptive clustering hierarchy with deterministic cluster-head selection
TL;DR: A communication protocol named LEACH (low-energy adaptive clustering hierarchy) is modified and its stochastic cluster-head selection algorithm is extended by a deterministic component to reduce the power consumption of wireless microsensor networks.
Proceedings ArticleDOI
Weighted Centroid Localization in Zigbee-based Sensor Networks
TL;DR: Weighted centroid localization (WCL) provides a fast and easy algorithm to locate devices in wireless sensor networks that is derived from a centroid determination which calculates the position of devices by averaging the coordinates of known reference points.
Proceedings ArticleDOI
Microservices approach for the internet of things
TL;DR: The microservice approach has created a hype in the domain of cloud and enterprise application business as mentioned in this paper, where one monolithic application is split up into a set of distributed services and those are strongly decoupled to enable high maintainability and scalability.
