Wireless Sensor Network

Wireless Sensor Networks (WSN) consists of a large number of small, batterypowered, inexpensive and wireless sensors which send their data wirelessly. More speci cally, a WSN consists of spatially distributed autonomous sensors to monitor physical or environmental conditions, such as temperature, sound, pressure, etc. Typically, data packets are generated by each node and are sent to a Base Station (BS) or a sink. Here the data is aggregated and forwarded to the user. Figure shows the basic architecture of a WSN…

Basic architecture of a wireless sensor network

In Wireless Sensor Network (WSN), nodes have to share the medium for data transmission. Therefore, Medium Access Control (MAC) protocol has been developed to provide collision free access through this common channel. Standard MAC protocols for WSNs can be categorized into synchronous, asynchronous and hybrid. Synchronous MAC protocols, specify the duration of wake-up and sleep time to reduce the unnecessary communication time and energy wasted in idle listening. One major drawback of these protocols is that they are highly dependent…
