Distributed Database Design with Genetic Algorithm and Relation Clustering Heuristic
نویسندگان
چکیده
We describe a genetic algorithm based heuristic for distributed database (DDB) design, Relation Clustering (RC). Relations in a database are allocated to nodes of a distributed database such that the total cost of executing a set of queries (each with a given frequency) over a time period is minimized. The experimental results are compared with another earlier GA based algorithm which shows about 15% improvement.

Due to the resource constraint and dynamic parameters, reducing energy consumption became the most important issues of wireless sensor networks topology design. All proposed hierarchy methods cluster a WSN in different cluster layers in one step of evolutionary algorithm usage with complicated parameters which may lead to reducing efficiency and performance. In fact, in WSNs topology, increasin...
