**12. The major applications of WSNs**

#### **12.1 Application of WSNs**

#### 1.**Logistics**

Logistics is a multi-player business which has changed significantly in the last decade. e.g. transport of food. **Figure 9** shows one application scenario, where

wireless sensor network nodes are connected to goods (mostly food because of their perishable nature). The goods are loaded from a storehouse or warehouse to a good carrier vehicle, in which their nodes need to be self-organize and form a network of nodes, which can forward information of the goods' from one state to the outside world using a gateway (e.g. a telematics unit).

Logistics benefits clearly from Wireless Sensor Networks. However, the requirements of logistics for applicable WSNs are challenging.
