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…
