Abstract. In recent years, the number of network devices which are being used in new network infrastructure and intelligent buildings, are growing more and more. Because these devices can often have high processing activity, we must consider their power consumption. Their energy requirements may vary depending on their operation mode, their processing capacity and even the type of devices to which are connected. The ability to determine exact consumption of network can provide an optimal network design and the other auxiliary systems, such as cool system, which may be necessary for the proper operation of the network. In this paper we determine the power consumption generated by network devices of different manufacturers and models. These tests allow us to see the energy consumed when they are in await mode and when they are working, running a routing protocol in order to interconnect different networks, promoting the development of the sustainable Green Networks.

Abstract. The development of low cost technology based on IEEE 802.11 standard permits to build telecommunication networks at low cost, allowing providing Internet access in rural areas in developing countries. The lack of access to the electrical grid is a problem when the network is being developed in rural areas, so that wireless access points should operate using solar panels and batteries. Many cases can be found where the energy consumption becomes a key point in wireless network design. In this paper we present a comparative study of the energy consumption of several wireless network access points. We will compare the energy consumption of different brands and models, for several operation scenarios and operating modes. Obtained results allow us to achieve the objective of this article, that is, promote the development of wireless communication networks energetically efficient.
