  • A Ubiquitous Publish/Subscribe Platform for Wireless Sensor Networks with Mobile Mules
    2012 IEEE 8th International Conference on Distributed Computing in Sensor Systems, 2012
    Co-Authors: Xiaoyu Tong, Edith C.-h. Ngai
    Abstract:

    Existing publish/subscribe architectures for wireless sensors networks only support stationary sensors interconnected with each other. They cannot handle mobile sensors or remote sensors that are sparsely deployed. In this paper, we propose a novel ubiquitous publish/subscribe system that supports data access from both mobile sensors and stationary sensors. Our system utilizes mobile phones as data mules to relay subscriptions and published data between broker and remote sensors. It provides content-based publish/subscribe services from sensors deployed anywhere without depending on any network infrastructure. We implement our publish/subscribe platform on real hardwares and test it in a Hiking Trail application. The application allows users to subscribe for sensing data from both stationary sensors and mobile sensors along Hiking Trails. Extensive experiments are conducted in an outdoor testbed to evaluate the system performances such data delay, number of data received and communication overhead.

  • avaliacao do potencial interpretativo da trilha do jequitiba parque estadual dos tres picos rio de janeiro evaluation of the interpretative potential of jequitiba Hiking Trail parque estadual dos tres picos rio de janeiro brazil

    Co-Authors: Silvia Marie Ikemoto, Moemy Gomes De Moraes, Professora Adjunta, Vivian Castilho Da Costa
    Abstract:

    RESUMO: O presente estudo avaliou o potencial da trilha do Jequitiba, Parque Estadual dos Tres Picos (RJ), para a sensibilizacao e conscientizacao dos seus usuarios atraves da Interpretacao Ambiental. Foram utilizadas as metodologias de caracterizacao biofisica da trilha, avaliacao da trilha quanto a Interpretacao Ambiental e o Indice de Atratividade dos Pontos Interpretativos (IAPI). A trilha do Jequitiba foi caracterizada como de leve dificuldade, curto percurso, com design apropriado para pedestres, sendo os impactos decorrentes do uso considerados minimos ou controlados. Atraves do IAPI, pode-se concluir que e uma trilha altamente atrativa, dotada de uma multiplicidade de recursos interpretativos. Apesar de possuir pontos de interpretacao consensuais, estes enfatizam conteudos biologicos e ecologicos em detrimento dos de cunho historico e cultural, alem de nao apresentar roteiros tematicos de interpretacao definidos. Embora nao atenda a todos os pressupostos da Interpretacao Ambiental, a trilha do Jequitiba pode ser considerada com carater e potencial interpretativo, no entanto, os aspectos frisados devem ser trabalhados de forma a implementar e desenvolver plenamente a Interpretacao Ambiental. Palavras-chave: Trilhas interpretativas.Unidades de Conservacao. Indice de Atratividade dos Pontos Interpretativos. Interpretacao ambiental.
