بخشی از مقاله انگلیسی: 1 Introduction Wireless Sensor Networks (WSNs) have become very popular in this current decade due to their wide range of applications in domestic, defense and industrial applications. Some of these appli- cations of WSNs can be used for different purposes such as target tracking, intrusion detection, wildlife habitat monitoring, climate control and disaster management [12]. The sensor node in the WSN consists of a sensor, embedded processor, moderate amount of memory and transmitter/receiver circuitry. They are normally battery powered and coordinate among themselves to perform a common task. The radio on a sensor node is usually the component that uses most energy. Not only transmitting costs energy; receiving, or merely scanning the ether for communication, can use up to half as much, depending on the type of radio [23]. Medium Access Control (MAC) layer is described by a MAC protocol takes care to ensure that no two nodes are interfering with each other’s transmissions by setting sensor nodes functions. While traditional MAC protocols are designed to maximize packet throughput, minimize latency and provide fairness, protocol design for wireless sensor networks focuses on minimizing energy consumption. The fairness is the secondary. Recent advances in energy efficiency in the wireless sensor networks have led to many new protocols specifically designed for sensor networks where energy wakefulness is an essential consideration [3]. To design a good MAC protocol for the wireless sensor networks, the following attributes are to be considered [14] energy efficiency, latency, throughput and fairness. Prolonging network battery lifetime for these nodes is a critical issue. Another important attribute is the scalability to the change in network size, node density and dynamic topology [15]. There is several attraction drawing considerable researchers into this fields of engineering. Major sources of energy waste in wireless sensor network are basically of four types [24] such as collision, packet overhead, idle listening and overhearing. In order to evaluate and compare the performance of energy conscious MAC protocols, the following matrices of research areas are: energy consumption per bit, average delivery ratio, average network throughput, and average packet latency. 1.1 Motivation Conventional MAC protocols have been optimized for maximum throughput and minimum delay. Because of the target, they are not suitable for wireless sensor networks. X-MAC uses less energy for all sleep periods and generation rates, and is less sensitive to network density. But in our adaptive D-MAC energy efficient MAC protocol dynamically selects the preamble periods and turns off the nodes to conserve the energy. 1.2 Contributions D-MAC protocol design methodology and results projected at self-learning, traffic adaptive algorithm for varying traffic conditions inherent to the WSNs. For this design the preamble periods to place the sensor node into power saving mode [20] and optimizing the traffic rhythm that tends the sleep duration to maximize the energy saving and minimizing power mode transition. The rest of the paper is organized as follows. Section II summarized the related work of existing protocol. Section III illustrates the proposed design principle. Section IV analyzes the D-MAC protocol algorithm that is adaptive energy efficient protocol. Implementation methodology of protocol Section discussed in section V. This is followed by the experimental setup and results are discussed in the Section VI. Finally section VII concludes the paper with future scope. |
