In the traditional scheduling scheme of the message ferry in wireless sensor networks, the route of a ferry is usually designed as a simple cycle. Closed Walk Ferry Route Design (CWFRD) aims to design the ferry route as a closed walk which contains more than one simple cycle to minimize the average weighted delay of the sensed data to the sink. In this paper, an Modified Ant Colony Optimization Algorithm (MACOA) is proposed to solve the CWFRD problem. The experimental results show that MACOA can greatly reduce the average weighted delay, comparing the previous proposed algorithms.

Subject. This article discusses the issues related to the creation of a technology of modeling and optimization of economic, financial, information, and logistics cluster-cluster cooperation within a federal district. Objectives. The article aims to propose a model for determining the optimal center of industrial agglomeration for innovation and industry clusters located in a federal district. Methods. For the study, we used the ant colony optimization algorithm. Results. The article proposes an original model of cluster-cluster cooperation, showing the best version of industrial agglomeration, the cities of Samara, Ulyanovsk, and Dimitrovgrad, for the Volga Federal District as a case study. Conclusions. If the industrial agglomeration center is located in these three cities, the cutting of the overall transportation costs and natural population decline in the Volga Federal District will make it possible to qualitatively improve the foresight of evolution of the large innovation system of the district under study.
