The digitization and integration of biodiversity data are essential for supporting environmental conservation sustainable use natural resources. Nowadays an increasing amount made available by regional, national global initiatives, but the efficient still a challenge. New techniques needed to enable manage these various types biotic abiotic generate useful knowledge decision-making processes. We present work in progress research that proposes computational framework information retrieval process.

Wireless Sensor Networks are networks suitable for data collection in harsh environments, where it would be difficult or costly the deployment of wired infrastructure. In spite these advantages, such often rely on batteries to operate, which may lead a serious limitation lifetime. Bearing this mind, article is proposed and tested hybrid polling approach that reduces number frames transmitted by router node. Thus, node lifetime can extended significantly hence network The technique becomes...
