An adaptive handoff algorithm can give high performance in dynamic and complex cellular systems. This paper proposes a new fuzzy logic based algorithm with a unified handoff candidate selection criterion and adaptive direction biasing. Known sensitivities of handoff parameters are used to create a fuzzy logic system, which serves as a mechanism to adapt handoff parameters. The unified handoff candidate selection criterion allows simultaneous consideration of several handoff criteria to select the best handoff candidate under given constraints. The proposed handoff algorithm also provides enhanced direction biasing by adapting the direction biasing parameters.
