Abstract: Low Power Wide Area Network (LPWAN) technologies are typically promoted for Internet-of-Things (IoT) applications, but are also of interest for emergency communications systems when regular fixed and mobile networks break down. Although LoRaWAN is a frequently used representative here, there are sometimes large differences between the proposed range and the results of some practical evaluations. Since previous work has focused on urban environments or has conducted simulations, this work aims to gather concrete knowledge on the transmission characteristics in rural environments. Extensive field studies with varying geographic conditions and comparative tests in urban environments were performed using two different hardware implementations. Overall, it was found that the collected values in rural areas are significantly lower than the theoretical values. Nevertheless, the results certify that LoRaWAN technology has a high range that cannot be achieved with other common technologies for emergency communications.

Abstract: One of the main design challenges of any Emergency Management System (EMS) is the diversity of users and responsibilities that must be considered. Modelling the access capabilities of different communities of users is a relevant concern for which the RBAC (Role-Based Access Control) paradigm provides flexible and powerful constructs. In this paper we describe how we used an RBAC meta-model to specify at different levels of abstraction the access policy of a specific EMS called ARCE (Aplicación en Red para Casos de Emergencia). This approach has made it possible to face access modelling at earlier development stages, so that stakeholders got involved in analytical and empirical evaluations to test the correctness and effectiveness of the access policy. Moreover, since the RBAC meta-model is embedded into a web engineering method, we put into practice a holistic process which addresses different design perspectives (structure, navigation, presentation, interaction and access) in an integrated way.
