Connectivity, Performance, and Resiliency of IP-Based CDMA Radio Access Networks

This paper examines Radio Access Network (RAN) connectivity and its impact on the performance and resiliency of the wireless network using different RNC selection algorithms. The proposed Min-Load-1 algorithm, which allows at most one hard handoff in order to accommodate each incoming request, delivers performance close to the standard Min-Load algorithm using a RAN of much higher connectivity and is close to the optimal algorithm using the same RAN. We also find that using Min-Load-1 algorithm and allowing the base stations to connect to two RNCs result in resiliency to RNC failures that is similar to having full-mesh connectivity between base stations and RNCs.
