Bottom Line: Currently, many rule-based HEMSs have been proposed and almost all of them assume "IF-THEN" rules.In the simulation environment, rules are processed by a smart tap that relates to the action part of each rule.In addition, we implemented the proposed system as HEMS using smart taps.

ABSTRACT
In recent years, sensors become popular and Home Energy Management System (HEMS) takes an important role in saving energy without decrease in QoL (Quality of Life). Currently, many rule-based HEMSs have been proposed and almost all of them assume "IF-THEN" rules. The Rete algorithm is a typical pattern matching algorithm for IF-THEN rules. Currently, we have proposed a rule-based Home Energy Management System (HEMS) using the Rete algorithm. In the proposed system, rules for managing energy are processed by smart taps in network, and the loads for processing rules and collecting data are distributed to smart taps. In addition, the number of processes and collecting data are reduced by processing rules based on the Rete algorithm. In this paper, we evaluated the proposed system by simulation. In the simulation environment, rules are processed by a smart tap that relates to the action part of each rule. In addition, we implemented the proposed system as HEMS using smart taps.

Mentions: Figure 2 shows an overview of the proposed system. In the proposed system, smart taps showed as N1, N2, and N3 are put all over the home and connected to LAN to communicate with each other. Electrical appliances are plugged in the smart taps placed near to or in the same room. Each smart tap feeds power to and controls the plugged-in electrical appliances. Sensors are plugged in the smart taps and connected to the LAN or publish observed data via resource networks such as wireless sensor network (WSN) [12–14] and semantic link network (SLN) [15, 16]. The observed data such as user's location [17] are referred from other devices. Smart taps collect related information from electrical appliances and sensors to process IF-THEN rules based on the Rete algorithm. The smart taps memorize the processing results per each condition matching on rules and share the processing results with each other on Pub/Sub model. By sharing the processing results based on the Rete algorithm, the number of processes and collecting data for other rules are reduced. The rules are managed intensively by a specific computer on the LAN. The computer is called home gateway (HG). The HG delivers rules to smart taps when the rules are updated, and all smart taps understand the same rules.
