Wireless Sensor Networks (WSNs) are endearing to researchers in view of their outspread application capacity in the multifarious domain such as object detection and tracking, industrial automation, environmental monitoring, smart home, and tactical system [1]. Typically, a WSN comprises of enormous low-cost and small sensor nodes which are deployed in an intended region to acquire data of interest. However, poor sensing range of a node evolves compact network, hence developing a dynamic Medium-Access Control (MAC) protocol is predominant. So far, a great number of MAC protocols have been presented with different ideas for wireless sensor networks. Initially, researchers’ prime consideration was energy efficiency. In the recent past, researchers have given priority to design a protocol that supports multitasking while being adaptive to traffic loads. In this paper, an attempt has been made to survey the numerous Primitive and Schedule-Based MAC protocols. At first, the properties of wireless sensors paramount for the design of MAC layer protocols are summarized. Then, the Primitive MAC protocols and Scheduled-Based MAC protocols are discussed, and finally, their advantages and disadvantages are emphasized. |
