Madhyam

  • A model for Educational Content Distribution

in network-challenged environments

  • Implemented the model and done feasibility

study to deploy it in real scenarios

Monitoring Point: Responsibilities

  • Collect Usage data(for Analytics) from Clients
  • Aggregation of usage data and generating

reports for Monitoring Authorities

slide-15

MOOC on M4D 2013

Analytics

  • At the mobile level

– Content usage

  • At the school level

– Attendance, content usage, Learning issues

  • At the Repository(nation/state) level

– Content design

Analytics

Problem - Huge data can be generated, there needs to be control on amount of data gathered Solution - Aggregation at every level of data upload

slide-17
SLIDE 17

MOOC on M4D 2013

Madhyam is about

  • Tolerance to intermittent connectivity
  • Mechanisms to control the flow of content in the

system

  • Mechanisms to analyze the usage of system
  • Simulations showed that the processing power and

storage capacity of inexpensive commodity hardware can easily run the proposed system.

Future Work

  • Similar systems in other verticals like healthcare,

agriculture and other government services can also be explored

  • Low cost Battery powered devices can be explored for

creating Delivery Points – see COL work

  • P2P content download can be explored to make system

more scalable
