Global Emergency System Based on WPAN and LPWAN Hybrid Networks

Abstract

There are multiple methods of communication for the transmission of every type of alarm. In the case of emergency systems, they are usually controlled by private companies that work as bridges between the source and the receiver of an emergency. Furthermore, it is necessary to use an independent communication system for each building, requiring human vigilance, leading to an increase in infrastructure and service costs as well as response time. This paper proposes a hybrid network by combining both wireless personal access network (WPAN) and low power wide access network (LPWAN) communication for the complete development of a communication architecture oriented to an emergency system. The main aim of this work is to provide a global emergency system that is focused on fire detection but is also suitable for other critical events, with low energy consumption, a wide communication range covering up to 50 km, and a low cost of service and infrastructure. This proposal reduces the total energy consumption of the system with respect to typical fire detection systems.

Flexible Thin Film-Based Triple Port UWB MIMO Antenna With Modified Ground Plane for UWB, WLAN, WiMAX, WPAN and 5G Applications

“…The frequency range under consideration is established based on the vertical dimension of the circular monopole antenna. This dimension may be obtained by using (3), which is given as…”

“…Hence, the resonant frequency that impacts this parameter has been shifted toward the lower end. Consequently, the dimensions of the circular patch can be determined using (3) reflection coefficient. TARC offers a more accurate way to quantify MIMO effectiveness as a result.…”

“…These connections include Wireless Local Area Network (WLAN), which is a local area connection facilitated by access points, as illustrated in [1]. Additionally, Wireless Personal Area Network (WPAN) connections link devices within an individual's vicinity, as depicted in [2] and [3]. Furthermore, Wireless Body Area Network (WBAN) connections enable communication between network equipment on the human body and measuring instruments, as demonstrated in [4] and [5].…”

Reinforcement-Learning-Based Robust Resource Management for Multi-Radio Systems

“…Multi-radio or multi-RAT (multi-radio access technology) systems allow exploitation of the diverse characteristics present in different wireless radio standards, which provides multiple advantages in power consumption and robust link maintenance [ 1 , 2 , 3 ]. Applications of the multi-radio paradigm are prevalent in two distinct categories: wireless sensor network (WSN)-focused scenarios and heterogeneous access for mobile networks [ 4 , 5 ].…”

Guidelines for Renewal and Securitization of a Critical Infrastructure Based on IoT Networks

“…Perez et. al in [29] propose WPAN and LPWAN hybrid networks used for global emergencies in Smart Cities. In the case of Smart water, [30] compares state-of-the-art methods to predict the water level in Catalan reservoirs.…”
