Online Educational Game of Snakes and Ladders -Shalini Pradhan -Manali Joshi -Uttara Paingankar -Seema Joshi

Introduction Computer mediated learning has gained a lot of popularity in the past decade. Learning is enhanced if this process is coupled with games. Interactive multiplayer games act as an excellent learning tool. The multi-player games have imposed a requirement on the Internet to support low-latency real-time interactions. It is essential that all the users / players get the same view in multi-user online games.

Objectives Design of an multiplayer interactive game Incorporating learning aspects in the game as a way of interaction Make the system distributed over a network Achieve a degree of “fairness” in the game Scalability Interoperability

Related Work Caching and Replication techniques to handle network heterogeneity. –The protocols proposed to handle consistency problems in distributed applications can help in dealing with heterogeneous clients. Use of Java technology for simulating real time synchronous collaborative systems like multi-user games. Use of replicated architectures for synchronous collaborative multi-user systems since they require low bandwidth and transfer minimal state information.

Related Work (contd.) Implementation of online games as virtual reality games where clients can see themselves within the game environment. –Dealing with security, synchronization and fairness issues in these systems. Implementation of a multiple-server model to handle huge loads of data. Issues like monitoring of resources are dealt with. Load balancing issues for dynamic change of workload in network games. Load-balancing algorithms have been proposed.

Proposed Solution

System Architecture

Technical Architecture

Technology and Tools Programming Language: Java (J Creator) Common Object Request Broker Architecture (CORBA): For communication between the application and the server CORBA is used. Database: MS Access JDBC – ODBC for database connectivity Environment: JDK 1.3 Client side web-interface: Active Server Pages

Why CORBA? Interoperability Scalability Heterogeneity CORBA Services

Flow Diagram No Yes User Login Check if user is registered Register New User Go to Game Page User DB

Flow Diagram contd… Game Page Check the Number of users Start Game Wait for users Throw Dice Is the Question Answered? Don’t proceed Give control the next user Advance appropriately By checking the Snake And ladder at each position Position Table When 100 is reached By one user display “END OF GAME” User DB

What we learnt ?????? Software Development Lifecycle Good Software Designing Skills Code Modularity Communication on CORBA Threads in CORBA – Identification not available in CORBA 2.3 JAVA AWT ASP

Future Work Extend the game to support more users per game session Extend the game to support more game sessions Incorporate levels of difficulty in the game Incorporate this game into a bigger framework of many other games Can be enhanced to support a variety of knowledge databases Users can assess their performances(Reports / Graphs)
