Generic Simulator for Users' Movements and Behavior in Collaborative Systems • Members: • GiladIvry • MattanMargalith • Niv Saar • Alex Surguch
Project Description In this project we will develop an application which simulates location based collaborative systems in big communities. In the simulator we will use real movement patterns derived from locations of people recorder over time. We will also combine different user behaviors in collaborative systems.
Project Purpose In order to launch a new cellular application, the customer wishes to simulate the usage of the application, and it’s spread in a given population at a given time.
Problem Domain • a lot of users • A LOT of statistics • A lot of parameters that will define the behavior of the scenario. • Different user types (groups) that behave and use the application differently. • Non- deterministic behaviors at most.
Problem Domain- Example Consider a communication service that enables every user to ask and reply to messages that are regarded to his whereabouts, using a cell phone.
Problem Domain- Example For instance, a person at his house in Ramat-Ganwants to know how crowded the Mall in Azriely Towers is.
Problem Domain- Example He then sends a query, using the system, and his message is routed to a group of users at the relevant location, using a smart selection algorithm that chooses each individual in this group.
Problem Domain- Example The receivers may respond or discard the message, but the relevant replies are routed back to the user, which now has an answer to his query, in a matter of minutes.
Solution Our solution is to build a generic simulator that will: • enable the user to configure a wide range of parameters and settings, thus manipulating every aspect of the scenario. • Run different scenarios, inject events and view the properties of different groups • Gather, display and compare variant statistical data.
Solution GUI Selection Incentives Simulator Query Evaluation Location Prediction DB
Non-Functional Requirements • Speed, Capacity & Throughput: • The application must launch in less than 2 seconds. • Each transaction of the system, tick, should be processed in under one second (under the assumption that the system has no more than 100,000 users, otherwise, computation time may rise), and the display of the GUI should refresh during this period of time, or during other user configured time. • The system is a web application and can support up to 10 users simultaneously.
Non-Functional Requirements • Reliability: • This system will remain online at all times. The system will be able to recover from data crashes and restore the data of previous runs from the DB. • Safety & Security: • The system's code will be protected by the server that it is loaded on. • The simulator does not require any permissions or security levels.
Non-Functional Requirements • Portability: • The application will run on a Microsoft Windows operation system and will be operable for Explorer and Firefox browsers only. • Usability: • Extensive learning of the software use will be difficult and is suited to expert users only (knowledge of the algorithms, probabilities and etc.). • For novice users, a setup wizard will be provided, which enables a quick and simple definition of the simulation.
Use case ID: 1 • Use case name: configure simulation properties • Primary actors: User • Description: The user will configure all the properties and input all the necessary initial data that are needed in order to run the simulation. • Trigger: The user will ask to configure new simulation. • Pre-conditions: None
Use case ID: 1 • Post-conditions: The new system configuration has been saved in the DB and the simulator is initialized with all the inserted data • Flow of events: • The user chooses the amount of simulated entities that will participate in the simulation. • The user chooses the general statistics for the simulated entities. • The user chooses how to arrange the simulated entities in the map.
Use case ID: 1 • The user chooses how the simulated entities will move on the map. • The user chooses the length of the simulation (number of ticks) and the duration of each tick in hours. • The user configures the special events. • The user configures how to generate the requests. • The user chooses the algorithms that he wants the simulation to work with. • Alternative flows: User can return to the previous step in the wizard
Use case ID: 2 • run the simulation • Primary actors: User • Description: The user will activate the simulation • Trigger: User presses the run simulation button. • Pre-conditions: a configuration for the simulation has been loaded. • Post-conditions: all the data from the simulation is saved in the DB and displayed for the user • Flow of events: • User presses the start simulation button. • Alternative flows: None.
