چکیده

Use of Wireless sensor networks have been widely seen in the fields of target detection and tracking, environmental monitoring, industrial process monitoring, and tactical systems.In wireless sensor networks nodes work with a incomplete power source, energy efficient operations in an important factor of the nodes in wireless sensor network. Energy conservation plays important role in different layers of the TCP/IP protocol suit, and for MAC layer it is the effective part. Therefore, to work in wireless communicating sensors network, we use MAC protocol which improve energy efficiency by increasing sleep duration, decreasing idle listening and overhearing, and eliminating hidden terminal problem or collision of packets. In this paper First section we describe the accessible energy –efficient MAC protocols for sensor networks their energy saving method. In Second section we discuss the architecture of same protocols and then compare same protocols depending on their Advantages and Disadvantages.

Multi-channel Medium Access Control Protocols for Wireless Sensor Networks: A Survey

Extensive researches on Wireless Sensor Networks (WSNs) have been performed and many techniques have been developed for the data link (MAC) layer. Most of them assume single-channel MAC protocols. In the usual dense deployment of the sensor networks, single-channel MAC protocols may be deficient because of radio collisions and limited bandwidth. Hence, using multiple channels can significantly ...

An Energy Efficient Clustering Method using Bat Algorithm and Mobile Sink in Wireless Sensor Networks

Wireless sensor networks (WSNs) consist of sensor nodes with limited energy. Energy efficiency is an important issue in WSNs as the sensor nodes are deployed in rugged and non-care areas and consume a lot of energy to send data to the central station or sink if they want to communicate directly with the sink. Recently, the IEEE 802.15.4 protocol is employed as a low-power, low-cost, and low rat...
