Comparison of performance of location-aware and traditional handoff-decision algorithms in CDPD networks

Abstract

Traditional handoff algorithms based on stochastic and heuristic models perform poorly as they do not account for the rapid changes in the radio environments. Adaptive handoff algorithms are being developed to solve this problem with a corresponding tradeoff in terms of computational complexity. This paper suggests a location-aware handoff decision algorithm. The performance of the traditional and proposed handoff algorithm in a cellular digital packet data network (CDPD) are compared using simulations. The results indicate that the location-aware algorithm performs better than the traditional handoff algorithm.
