In this paper we propose a data selection method based on clustering to reduce the amount of transmissions in a water-quality monitoring system. Recently, some studies are focusing on transmission of the core data collected from the sink nodes of sensor networks. K-means clustering may be a good method for this purpose. Our suggested method, based on K-means clustering, has the outstanding features of selecting unusual data and choosing representative properties of usual data. These features make it possible to reduce the amount of transmissions by removing unnecessary duplication of data. From the experimental results, we found that our method outperformed the related research.

In heterogeneous networks, devices can communicate by means of multiple wired or wireless interfaces. By switching among interfaces or by combining the available interfaces, each device might establish several connections. A connection is established when the devices at its endpoints share at least one active interface. Each interface is assumed to require an activation cost, and provides a communication bandwidth. In this paper, we consider two fundamental optimization problems. In the first one, we aim to activate a set of interfaces in the network G = (V, E) in order to guarantee the maximal bandwidth between two given nodes. Nodes V represent the devices, edges E represent the connections that can be established according to the availability of the interfaces in the devices. In the second problem, we look for activating the cheapest set of interfaces among a network in order to guarantee a minimum bandwidth B of communication between two specified nodes. We show that the first problem is polynomially solvable while the second one is NP-Hard. However, we experimentally analyzed an algorithm for the second problem, showing that in practical cases it guarantees a low approximation ratio which allows us to use it in real-world networks.
