Optimization of segment size assuring application perceived QoS in healthcare

Advances in the information and communication technology are significant for the improvement of healthcare services especially in rural areas of developing countries. This is also one of the United Nations Millennium Development Goals. In this work, we proposed a ubiquitous healthcare network and computed the optimum transmission segment size for applications needed to guarantee the perceived quality of service. This has been carried out through NS2 based simulation of a state wide area network infrastructure implemented in Himachal Pradesh, a state in the Western Himalayan region of India. The various types of healthcare applications and services have been classified into according to their QoS requirements as per guidelines in ITU report on network performance objectives. The infrastructure specific optimum values of segment size for these classes of applications running on TCP traffic are computed
