We have developed a prototype that uses medium range smartphones running on the Android platform, to collect and register accelerographic data of the movement experimented by buildings or civil structures during a seismic event, in order to identify potential hazard of structural failures. At the moment the National Accelerographic Network, system managed by the Venezuelan Foundation for Seismological Research (FUNVISIS), uses an ETNA accelerographs platform to record and collect accelerographic data for the study and evaluation of seismic events. In this research we are interested in evaluating how good is the data collected by our prototype against the data that could be obtained by a current professional platform in order to identify the potential applicability of our prototype as a part of the FUNVISIS platform. Our prototype uses smartphones as a system of sensor nodes that are always in recording mode. The devices will be placed on specific fixed locations of a structure where the movement feels more intensely to detect if the acceleration suffered has been so strong that exceeded the threshold identified for this particular civil structure. The threshold for each construction is based on the seismic resistant standards and the charge distribution of the building structure. The purpose is to generate an early warning during the occurrence of a seismic event that could be able to prevent people to stay in buildings that may be considered hazardous and that should require an expert evaluation before it could be in use again.

Si fuese posible conocer cuáles de estas estructuras se encuentran en peligro o han sufrido daños significativos, los recursos empleados para responder ante la situación de emergencia, pudiesen ser utilizados de manera mucho más eficiente. Es por esto que se plantea el diseño de una aplicación, que haciendo uso de tecnologías de bajo costo, reducido consumo energético y que funcionando bajo el paradigma del Software Libre, le permita al personal experto, identificar rápidamente aquellas edificaciones cuya estructura pudiera estar comprometida. Esto se puede detectar al colocar una serie de sensores que registren si el movimiento de la edificación ha sobrepasado un umbral máximo establecido, en función de sus características estructurales y de las normas sismo-resistentes que aplican en la región, lo que implica que su estructura pudiera...

SHRP also provides both reliability and a load balance solution. As a novel proposal, it is a proactive protocol that chooses efficient routes, by selecting just the nodes that can contribute to extend

This proposal describes an innovative approach in the methodologies of post-seismic evaluations of urban zones in Venezuela. It is based on the developing of a platform based on wireless sensor networks, adjusted to the demands of data traffic after an earthquake event, according to the previously identified information needs, assuming that a partial or total collapse of traditional communication services in the disaster area is a real possibility. This work establishes some guidelines for the development of a tool that contributes to the process of identification of potentially affected buildings for an earthquake event. It also describes a proposal for the communication process of the collected data outside the disaster area using the infrastructure of a wireless sensor network and the resources and strengths in telecommunications, available in the Venezuelan Foundation for Seismological Research, without requiring the presence of experts in the event place to perform the first preliminary diagnosis. The proposed system will also help in the decision making process to allocate the available qualified personnel to the structures that really require it for damage evaluation. The incorporation of the wireless sensor technology in the process of post-seismic assessment could be an important management strategy with implications not only in a reduction of the costs associated with the use of equipment and communication technologies, but also in speeding the identification of structures that may be affected by a strong seismic event.

This feature, in addition to the use of wireless communication networks are offering the possibility to build wireless sensor networks using smartphones as sensor nodes, in order to collect and transmit data from its surrounding environment. Unfortunately, by the nature of RF, wireless networks are disturbed by many factors, which could affect the devices communication and their ability to deliver collected data, such as signal attenuation and radio interferences. Because of these facts implementing a network of smartphones that use WiFi communication implies that devices should be situated, in a way that they can communicate with each other. To deal with this situation, there is a set of commonly used tools for the site survey process, among them are spectrum analyzers and packet sniffers to measure the RF signal range and to evaluate the potential for interferences. In this work, we implemented an traffic testbed that can help significantly during a site survey process, identifying if the communication between Android smartphones can be effectively reached, even though they have being placed distant from each other.
