Survey on wireless sensor networks using MAC protocol

Wireless Sensor Networks are heavily applied in many domains. WSN consist of two or more sensing nodes which have capacity to sense compute and transmit-receive. WSN was initially developed for military and disaster rescue purposes. The salient features in Wireless Sensor Network make it special among other networks are; self-organization, low electricity usage, low memory usance, low bandwidth requirement for communication, large-scale nodes, wireless and infrastructure-less architecture. However each node in the sensor network is comprised of its own sensor, processor and radio transceiver, so each of the sensor-nodes have the ability to sense, process the data and the analysis of the data collected can be transited over the network to communicate the results with each other. There is a great range of domains and research areas where the WSNs have places, such as patient tracking, target tracking etc. In this survey various existing MAC protocols are discussed and compared with each-other.
