A corrected proof of a theorem due to Kumar (Fuzzy Sets and Systems 48 (1992) 267-271 ) is also provided. A counterexample is constructed to show that the arguments used by Kumar in his proof of the theorem are false. (~) fallacious arguments to establish his claim. Moreover, in his construction, there is an inherent drawback, which we shall remove here. Also, we provide a corrected proof and present a counterexample for the incorrect agruments used in . 0165-0114/99/$ -see front matter ~)

Because of this, there is always some discrepancy between traffic originated by the mobile station (MS) and that of received by the base station (BS). A probability model is used in this paper to evaluate this discrepancy considering geometry of the service area and probability density function of user distribution. Blocking probability experienced by the BS is found less than that of evaluated from the offered traffic of user end, which is the central idea of this paper. Furthermore, the same traffic model is applied to an ad- hoc two hop relay mobile cellular system for performance evaluation.
