A novel approach for generic home emergency management and remote monitoring

Abstract

This paper presents a novel home emergency management system (HEMS) for managing home emergency situations. The proposed solution is a generic and based on normalized technologies. First, we have identified a set of requirements that a robust HEMS should satisfy (interoperability, security, mobility, etc). Then, we have opted for an extended finite-state machine to detect and manage emergency situations. We also adopted WebRTC to enable communication in an interoperable manner. For securing our HEMS, we have used HTTPS, password, contextual role-based access control, and we have finally installed all the public servers into a protected area. The result obtained from the test-bed demonstrates that the proposed HEMS fills all the listed requirements. Furthermore, it gives very interesting results in terms of round-trip delay time and scalability.

Audio and Video Mixing Method to Enhance WebRTC

“…Tiberkak et al [8] proposed a family emergency management system that uses WebRTC for interoperable communication. Khan [10] introduced a new video teleconferencing approach based on physical or virtual action behavior, thus increasing the sense of presence in virtual reality.…”

“…The audio (video) data packet preprocessing module preprocesses the received audio and video data packets. According to the WebRTC specification [8], audio and video are sent by different channels with the identifiers in their respective header information. As a consequence, audio and video data packets should be preprocessed separately: their respective data packets need to be preprocessed after being received.…”

“…According to the WebRTC specification [8], WebRTC adopts the standard RTP format when packetizing streaming media data [8]. In the header of the RTP packet, the seq_number and timestamp are important parameters for this study.…”

“…WebRTC based on the UDP protocol provides a fast and stable streaming media communication framework without plugins in web pages [3]. Therefore, various application scenarios have been implemented, e.g., health care [4], remote collaboration [5]- [7], online monitoring [8], and online entertainment [6], [9], [10].…”

Set Theory-based FSM for Managing Home Emergencies Concept, Properties and Process Algebra

“…According to our previous study [8], the most suitable methodology to remedy the main drawback of rules-based systems (i.e., infinite loops) would be to use a FSM (Finite States Machine). FSMs are used in several works to handle issues related to smart home.…”
