Abstract(s)
Os recentes desenvolvimentos na a´rea das redes de sensores sem fios (Wireless Sensor Networks, WSN), originaram not´orias melhorias ao n´ıvel do seu hardware e software e, por consequˆencia, melhorias na sua viabilidade, condi¸c˜oes de implementac¸˜ao, custos e tempo de vida u´til. Por estas raz˜oes, s˜ao cada vez mais os projetos que tiram proveito destas potencialidades, abrangendo os mais diversos campos de aplica¸ca˜o, desde o militar at´e `a domo´tica. O projeto WISE-MUSE, baseia-se na implementac¸˜ao de WSN em ambientes interiores (indoor), e tem como objetivo a monitoriza¸ca˜o remota de paraˆmetros ambientais, vitais neste caso espec´ıfico, a` gest˜ao dos artefatos expostos no Museu da Baleia. Este tipo de WSN, indoor, define-se por uma maior densidade de obsta´culos (paredes), logo com distˆancias de transmiss˜ao mais curtas, uma maior refexa˜o dos sinais, mas tamb´em pela sua flexibilidade na implementa¸cao. O estudo destas carater´ısticas, executado com o recurso a um simulador de rede, permite na˜o so´ manter a rede do museu em pleno funcionamento, como tamb´em ter flexibilidade ao n´ıvel dos cena´rios gerados e capacidade de otimiza¸ca˜o. Com base nas simulac¸˜oes realizadas, procedeu-se a` ana´lise da topologia, do seu (sobre) dimensionamento e da (sobre) carga na rede, determinando no decorrer do processo, indicadores como a melhor posi¸ca˜o te´orica da estac¸˜ao base e a sua capacidade m´axima de transmissa˜o para uma determinada taxa de envio de pacotes. Apesar de apresentada no contexto do Museu da Baleia, considera-se a metodologia utilizada, va´lida, num contexto mais abrangente de cen´arios indoor.
Recent developments in the area of wireless sensor networks (WSN) have led to significant improvements in their hardware and software and, consequently, improvements in their viability, implementation conditions, costs and lifespan. For these reasons, there are more and more projects that take advantage of these potentialities, covering the most diverse fields of application, from military to home automation. The WISEMUSE project is based on the implementation of WSN in a indoor environment, and aims to remotely monitor environmental parameters, vital in this specific case, to the management of the artifacts exhibited at the Whale Museum. This type of indoor WSN is defined by a greater density of obstacles (walls), therefore with shorter transmission distances, a greater refection of the signals, but also by its implementation flexibility. The study of these characteristics, executed with the use of a network simulator, allows not only to keep the museum network fully operational, but also to have flexibility in the scenarios generated and the ability to optimize the current solution. Based on the runned simulations, we analyzed the topology, its (over) sizing and (over) loading, determining in the the process, indicators such as the best theoretical position of the base station and its maximum transmission capacity for a given packet rate. Although presented in the context of the Whale Museum, the methodology used is considered valid in a more comprehensive context of indoor scenarios
