Abstract

Sustav Global Sensor Networks primjereno je rješenje za olakšavanje rada s bežičnim mrežama osjetila. GSN web-aplikacija dio je sustava koji omogućuje dohvat i prikaz podataka korisnicima kojima je potrebno jednostavno grafičko sučelje preko kojega je moguće iskoristiti sve što nudi GSN međuprogram.
Nadogradnja web-aplikacije olakšana je modularnim dizajnom korištenjem AngularJS razvojnog okvira i upravljanjem paketa Bowerom. Konačno usavršavanje i dokumentacija puta podataka važno je za budući razvoj usmjeren naprednom grafičkom prikazu.
Web Storage mehanizam omogućava pohranu korisničkih postavki u memoriju aplikacije na korisničkom računalu čime se ubrzava i olakšava rad. Promjenama na dijelovima aplikacije u kojima se prikazuju podaci stavljen je naglasak na grafički prikaz i istovremeni pregled te usporedbu većih količina podataka. Veća robusnost ostvarena je provjerama dostupnosti potrebnih modula u situacijama kada ne postoje povoljni uvjeti za izvršavanje (nedostatak Internet veze) i ograničenjem količine podataka kada bi ona mogla dovesti do smanjenje brzine izvršavanja. Izdvajanjem widgeta, koji korištenjem Web Storagea dobivaju veći smisao, u zasebnu direktivu u skladu s načelima Angulara, omogućene su njihove daljnje nadogradnje bez narušavanja postojećeg stanja.

Abstract (english)

Global Sensor Networks is an adequate solution for facilitating Wireless Sensor Network management. GSN Web application is a part of the system which enables data queries and visualization for users who require a simple Web interface which exposes all essential functionality of the GSN middleware.
A modular design using the AngularJS framework and Bower package management eases the upgrade process. Polishing and detailed documentation of the datapath will prove important in future developments of an improved visualization-based Views.
The Web Storage API off offers mechanisms for storing the user's settings into the local memory which speeds up data lookups and improves user experience. Data-based View has been focused on visualization of data, displaying of multiple charts and comparison of various datasets. Robustness of the application has been improved by introducing mechanisms of checking for the presence of all the necessary modules which used to produce bugs in conditions where no Internet connectivity was detected. The maximum amount of data requested has been limited to prevent performance degradation. With the introduction of Web Storage, the Home page widgets might prove useful in future upgrades and have therefore been reintroduced as a custom directive, with accordance to Angular principles
