Dynamic Channel Allocation For Linear Macrocellular Topology

In this paper, we present a dynamic channel assignment scheme for highway macrocellular networks that is suitable for real-time services in terms of execution overhead and efficient in terms of reducing call blocking. The scheme can be used in a large segment of global highways, namely, linear macrocells in which the radio channels used in a given cell cannot be simultaneously used in two neighboring cells to its left and to its right. The scheme has the advantage of low execution time, small number of transmitted messages per request and low space overhead. By using a non-compact initial assignment of nominal channels, the scheme greatly simplifies the channel selection process and avoids the expensive computation and message exchanges typically used in dynamic channel allocation schemes. Performance simulation results show that the scheme also achieves low blocking probability and is therefore suitable for real-time connections in highway cellular networks
