Hybrid channel allocation in wireless network using evolutionary strategy

Abstract

Radio spectrum is limited resource in wireless mobile communication system. Cellular system has to serve the maximum possible number of calls while the number of channels available is limited. Hence the problem of determining an optimal allocation of channels to mobile users that minimizes call-blocking and call-dropping probabilities is of paramount importance. This paper proposes a hybrid channel allocation model using an evolutionary strategy with an allocation distance to give efficient use of frequency spectrum.
