Design of Efficient Queuing System in Cooperative Wireless Diversity Networks for High Speed Data Transmission Applications

摘要

Cooperative Diversity (CD) is a method in which different radio terminals deliver to each other for developing the total network channel capacity. We propose a high speed data transmission using efficient queuing system in wireless diversity networks. It provides the simultaneous data transmission of data for multiple users and increases the amount of data packets. To develop the robustness in ad hoc networks, the CD-MAC algorithm is introduced in the physical layer. The MIMO technique sends and receives the same data signal simultaneously on a single radio channel. OFDM is a Frequency-division multiplexing scheme used to reduce the interference. The ALOHA in cooperative diversity has the drawback of low throughput under heavy load conditions and collision. It sends the messages any time they want. Introduction of Slotted ALOHA Buffer CD it is expected to add some more advantages reduce the delay and transmits data packets simultaneously for achieving the high channel utilization with less interference. Queuing is used to increase the coverage optimization. The Wireless Channel's broadband characteristics improve the ALOHA network protocol performance.
