| Abstract | The ICT sector has developed with various types of technologies in the world today. With the improvement of the technology the customer demand for high quality services have increased. To satisfy customer demands technologies, with high data rates and wide channel capacities are required. These high quality technologies create traffic in the channels, collisions of data, error detection and correction due to errors produced in the transmission and much more complexity in the communication networks. This results a massive amount of energy consumptions in the networks. The energy consumption has a drastic impact on the environment, the economy and the technical unit. Since the global warming has become a major problem faced by the world in the present, greenhouse gas emission (mostly Carbon produced by ICT sector) must be reduced to keep the global temperature under control. Because of high consumption of energy in the equipment of the networks, there is considerably high expenditure related to the power supply in networks. This affects the economy growth. The heat dissipation due to the huge amount of power consumption leads to technical issues such as failed/over loaded network devices and poor performance in the equipment of the network. Therefore reduction of the power consumption in networks is an intensive need that has been discussing in many research papers today. Considering this situation, the purpose of this project is to implement a power saving MAC protocol which transmits data with possible minimum power consumption in the network. This simulation is done using two algorithms that are introduced to the field already. Path selection mechanism and 802.3az EEE. The aim is to combine these two mechanisms and implement a protocol that saves more power than in the two mechanisms separately. In this combined algorithm the best path is selected with minimum power consumption to transmit data and nodes are assigned to a low power mode (sleeping mode) which has a very low amount of power consumption such as 0.1 W, when they are not involved in any transmission in the channel. This reduces the unnecessary power consumptions of the entire network. The simulation is done using NFSNET topology and based on 802.3 Ethernet. A network of 14 nodes was tested for both constant bit rate and variable bit rate. And the power consumption was successfully reduced comparing to the two already existing mechanisms used. And it is also shown that the best performance can be gained when a variable bit rate is used for the transmission. |
