An application domain that makes use of wireless sensor network technology can be found in the area of medical monitoring. This field ranges from monitoring patients in the hospital using wireless sensors in order to remove the constraints of tethering patients to big bulky, wired monitoring devices to monitoring people in their everyday lives to provide early detection and intervention for various types of disease. This paper discusses scenarios where these sensors which vary fromminiature, body-worn sensors to external sensors such as video camera or positioning devices are applicable and presents a report of ongoing research on telemedicine at FUTA Akure.

Sensors are everywhere, which includes space, air and ground. Earth phenomena such as disasters also occur everywhere; such as wildfires, floods and volcanoes. There is a need to rapidly deploy existing sensors to aid emergency workers and investigators. The vision for our effort is to provide users the capability to create “mash ups” (a web application that combines data from more than one source into an integrated experience), similar to that used by Google Earth users to create a composite map with overlays of sensor information and from other data sources such as weather, traffic, urban construction etc. We make use of Web 2.0 technology and Open Geospatial Consortium (OGC) Sensor Web Enablement (SWE) web service standards to enable access to Earth’s sensors is an emerging mega-trend which will lower the cost of producing customized science by an order of magnitude. This paper will outline the key aspects of our experiments to date and implications for the future and in particular the Global Earth Observation System of Systems (GEOSS) international effort.

Summary As the widespread use and acceptance of Bluetooth continues concerns are being raised related to security vulnerabilities and privacy issues inherent in the use of this technology. Inadequate device resources and lack of user awareness has compounded this issue where the emphasis on design constraints, functionality and ease of use sometimes outweigh security concerns. Recently some concerns have being highlighted relating to the possible security vulnerabilities in commonly used devices, and also the possibility of the imperceptible tracking of device users through the use of distributed and connected Bluetooth sensor nodes.
