Analysis and Design of a Reliable Packet Transfer Mechanism for WIMAX

Today is the world of mobile and wireless communication. With the increase of its use there are some problems still under research regarding WIMAX. One of such major problem is the security. Security is always the main issue for any network and with the wireless network it requires more concern. This work is also presented in the same area. We are presenting our work regarding the liability of the data on the arrival side. This data can be a voice or some digital data. Over the network the Active attacks are very common. The proposed approach will provide a reliable packet marking in such network. We are proposing the probabilistic packet marking with the inclusion of four other approaches. i) A Definite Randomize packet marking approach to decide the transmission path. ii) An approach to trace back the path to identify the visited route. iii) A combination of Context based and Dictionary based encoding approach to verify the transmitted data. iv) A Checksum will be applied to vary the alteration of data. The proposed system will result more reliable transmission on WIMAX.
