OVERVIEW The need for wireless services is growing extremely fast, but the radio spectrum has bounds imposed by practical limitations on the circuit designs and use regulations from federal governments. Spectral efficiency is therefore of primary concern in the design of future wireless data communications systems. Efficiency of a wireless cellular system may be achieved at several levels of th...

One important quantity in assessing the viability of local, autonomous, dynamic channel allocation for microcellular systems is user capacity, defined as the average number of users per channel per cell. Here, we determine the capacity for infinite linear and planar arrays of microcells using a very idealized environment. In particular, propagation and interference considerations are simply rep...

Channel allocation algorithms can be classified into three methods. This paper is based on the fixed method. We propose a new fixed channel allocation mechanism using genetic algorithm in cellular mobile computing environments. Our simulation result indicates that the proposed algorithm could reduce a search time for an available channel.
