Evaluation of IoT Device Management Tools

Industry 4.0 with IoT (Internet of Things) is the next wave in technology revolution which is expected to change our everyday life. This digitalization is having great impact on all the domains (energy, healthcare, transportation, manufacturing etc.) in addition to the ICT (Information and Communication Technologies) sector. In IoT scenarios, numerous sensors measure and report several phenomena and diversified IoT solutions are deployed to collect huge amount of data. IoT platforms, such as Amazon AWS, IBM Watson or Microsoft IoT Suite, have been available to aid the development of such services/applications. However, one of the major challenges faced by IoT solutions providers is the supervision and management of the large number of deployed sensors/devices. Presumably, the magnitude and heterogeneity of the IoT systems makes it difficult to manage them with conventional IT management tools and techniques. New techniques and tools have to be explored and developed or the traditional management solutions have to be adapted to the new challenges. In this paper, we identify and formulate the essential challenges of IoT device management and supervision, review the actual state-of-the-art IoT device management and supervision techniques and tools available on the market, and briefly evaluate their features and typical use cases

Influence of Allium Sativum (Garlic), Zingiber officinale (Ginger) and Syzygium aromaticum (Clove) Extract against Larvae of Aedes mosquitoes (Culicidae: Diptera)

Mosquito control has become more difficult due to the unsystematic use of synthetic chemical insecticides which have inauspicious effect on the environment. Botanical phyto-chemicals with mosquitocidal potential are now recognized as potent alternative insecticides to replace synthetic insecticides in mosquito control programs due to their excellent larvacidal activities. The present study assessed the influence of A. sativum (garlic), Z. officinale (ginger) and S. aromatic (clove) extracts against Aedes mosquitoes. Larvacidal activities of three indigenous plant extracts were studied in the range 5.0 to 30.0mg/l in the laboratory bioassay against fourth instar larvae of Aedes sp. The mortality were subjected to probit analysis to determine the lethal concentration (LC50) to kill 50 percent of treated larvae of Aedes sp. Data obtained were analyzed by Comparing experimental groups and control groups with significance level established at p<0.05. All plants tasted showed effects after 24hrs of exposure at different concentration (mg/l). However the highest mortality was found in A. Sativum (garlic) and Z. officinale (ginger) against larvae of Aedes mosquitoes with LC50 = 42.50% (2.685) and LC50 = 30.01% (4.461) mg/l, while S. aromatic(clove) was found to have lowest mortality at LC50 = 24.50% (5.52) respectively. It is therefore recommended that A. sativum(Gallic), S. aromatic (Clove) has showed larvacidal effects against Aedes mosquitoes and could be served as alternative form of botanical control against mosquitoes .
