A Survey on ?Energy Efficient MAC Protocols with Differentiation in Traffic for Wireless Sensor Networks?

In Wireless Sensor Network (WSN) there are sensor nodes deployed to communicate with the physical world. These nodes are battery operated which consumes more power. One of the major issue for power consumption is to make an energy efficient medium access (MAC) protocol in the WSN. These sensor nodes are also affected by external factors like Packet Delivery Ratio (PDR), Throughput, End to End Delay and Latency to degrade the Quality of Services (QoS). Different traffic loads plays an important role in energy consumption. In this paper, we surveyed some MAC protocols for WSN and compare their design and behavior in accordance with different Traffic of loads.
