Congestion Avoidance in IP Based CDMA Radio Access Network

CDMA is an important air interface technologies for cellular wireless networks. As CDMAbased cellular networks mature, the current point-to-point links will evolve to an IP-based Radio Access Network (RAN). mechanisms must be designed to control the IP Radio Access Network congestion. This Paper implements a congestion control mechanism using Router control and channel control method for IP-RAN on CDMA cellular network. The Router control mechanism uses the features of CDMA networks using active Queue Management technique to reduce delay and to minimize the correlated losses. The Random Early Detection Active Queue Management scheme (REDAQM) is to be realized for the router control for data transmission over the radio network using routers as the channel. The channel control mechanism control the congestion by bifurcating the access channel into multiple layer namely RACH, BCCH and DCH for data accessing. The proposed paper work is realized using Matlab platform.
