Performance evaluation of a mobile cellular network with two hop ad-hoc relaying

Abstract

In a mobile cellular network, both new originating calls and handoff calls can be dropped at any time in the midst of a conversation when a user enters in a dead spot. 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.
