Modification of the collective dynamic routing method in heterogeneous networks

In the heterogeneous networks, a complex signal-interference environment is formed, characterized by a intra-system interference high level, which significantly reduces the heterogeneous networks throughput. One of the ways to increase such networks throughput by effectively reducing the intra-system interference influence is to use the integrated optimization method of these networks. However, its application is hampered by the complexity of implementing the collective dynamic routing method that underlies it. Therefore, modification of the collective dynamic routing method in relation to large heterogeneous networks is relevant. As a result of the application analysis of the collective dynamic routing method for optimizing the data flows distribution in heterogeneous networks, it is shown that the main limitation of this method applicability is the computational complexity of finding the optimal data transmission route. For this value the corresponding expressions are obtained. A modification of the collective dynamic routing method has been developed, in which the influence of intra-system interference is taken into account at the subnet segment level, and data distribution between subnets is carried out at the zone level. Using the obtained expressions, it is shown that the computational complexity of implementing the collective dynamic routing method in this case depends only on the number of users in the zone, which ensures the scalability of such a solution. Therefore, the use of the developed modification of the collective dynamic routing method will make it possible to use it to increase the throughput of large heterogeneous networks.
