The internet is used for wide variety of applications in wired, fixed wireless and mobile wireless environment. The requirements of one application / environment will vary from another application / environment. The challenge for the service provider is Quality of Service (QoS). The wired network has less complexity compared to fixed wireless network with respect to QoS. Certainly, the challenge for the service provider is further increased in mobile wireless network. This paper proposes a QoS strategy to select an appropriate coding scheme for any application based on the characteristics of coding schemes and data rates provided by the General Packet Radio Service (GPRS). This paper also analyzes coding schemes with various internet applications and QoS parameters like reliability, delay and bandwidth. The outcome of our strategy and analysis will help to select an appropriate coding scheme and to reduce the complexities involved in the data transfer with respect to the above parameters in wireless mobile networks.
