    Composition of location based services in decentralized registry based architecture
    (Springer Verlag, 2013) Kumari, K.; D'Souza, M.; Ananthanarayana, V.S.
    The massive growth of wireless communications and mobile database technologies has transformed the cell phone from being a mere portable phone to becoming an essential medium for contact, information and entertain-ment. A new trend has been evolved in mobile services which are used to provide user location based experience. It has opened a golden door for location based services. Location-based services denote services provided to mobile users according to their geographic location. There are two registry based archi-tecture, one is centralized and other is decentralized. In centralized architecture, first location of the user is determined and then central registry is looked up for requested services. In decentralized architecture, each of the location is sup-posed to be associated with a local registry which would be looked up for the requested services. But decentralized architecture is not able to give the information about services available in location other than user’s present location. There are a number of real world problems, which gives emphasis on the need of advance knowledge of availability of services present in other location and fulfillment of the total goal. Hence, in order to fulfill the above need, a methodology has been proposed in this paper. It minimizes the user involvement to a great extent in order to avail any online service. In this, composition plan would be created a priory to execution of services and selection of services would be based on QoS parameters in order to minimize the total cost. © Springer-Verlag Berlin Heidelberg 2013.

    Development of Smart Drip Irrigation System Using IoT
    (Institute of Electrical and Electronics Engineers Inc., 2018) Math, A.; Ali, L.; Umesh, U.
    India is a country with agriculture having paramount significance. Hence it is important to irrigate the plants in an astute way to get good production by maximizing the yield per unit space. Irrigation is the supply of an appropriate amount of water to the plants at a precise time. The objective of this endeavour is to irrigate the plants using the smart drip irrigation system within National Institute of Technology Karnataka campus. To achieve this, open source platform is used as a central controller of the system. Various sensors have been employed which continuously provide the existing parameters of factors governing healthiness of plants. Based on the information obtained from the RTC module water is supplied to the plants at regular interval of time by controlling a solenoid valve. The entire irrigation system can be monitored and managed by the webpage. This web page has a facility for controlling the irrigation of plants, both in manual and automatic fashion. The health of the plants is monitored by a raspberry pi camera which gives live streaming to the webpage. Water flow sensor accords information about water flow to the controller by the means of wireless communication. This information is analyzed by the controller to find out leakages in the pipe. Further, weather prediction is carried out, so as to regulate the quantity of water being administered thus making it more reliable and efficient. © 2018 IEEE.
