| Abstract: | The transmission capacity of CDMA Wireless Ad Hoc Networks is constrained by the mutual interference of concurrent transmissions among nodes.This paper studies the transmission capacity and throughput of CDMA Wireless Ad Hoc Networks from the view of the information flux among nodes,and makes a research on the impact of interference among nodes on transmission capacity of networks.The paper concludes and proves a sufficient condition to support the successful transmissions among nodes,and at last,some simulations is given and the validity of the results of paper is testified and a fit equation for information flux among nodes also is proposed. |
