Optimal Design of Multiple Fractional Guard Channel Policy in Multiservice Cellular Networks

In this paper we compute the optimal configuration of the Multiple Fractional Guard Channel (MFGC) admission policy in multiservice mobile wireless networks. The optimal configuration maximizes the offered traffic that the system can handle while meeting certain QoS requirements but computing the optimal parameter setting of this policy can constitute a high computational cost. To face these computational limitations an approximation based on Kaufman & Roberts recursion is evaluated and an algorithm is proposed. Moreover, we also propose an adaptative algorithm.The numerical results show that it is not easy to find a fast and accurate algorithm, in this sense the adaptative method yields the best results.
