Mobility management and routing algorithms for soft handoff in wireless mobile data network using MGCP

We propose a soft handoff method in packet network for CDMA mobile station and three delay constrained routing algorithms for this application that find a tree between multiple sources and multiple destinations. The proposed algorithms, which provide guaranteed QoS (quality-of-service) services at the network layer, are also designed to find reduced-cost routing trees. The proposed algorithms are verified by simulation, and three algorithms' performances are compared in view of the total tree cost and maximum end-to-end delay.
