What is IoT
The Internet of Things (IoT) is the interconnection of uniquely
identifiable embedded computing devices within the
existing Internet infrastructure. Typically, IoT is expected to offer
advanced connectivity of devices, systems, and services that
goes beyond machine-to-machine communications (M2M) and
covers a variety of protocols, domains, and applications*.

Hinweis der Redaktion
Yeah they can even better than human.? But the problem how is the accuracy of their sensing
The room occupancy is an example of the drawback of the motion detectors since they may switch off the light and the heater, etc. if the persisted person doesn’t make any motion, therefore there is a need to collaborate these detectors with another thermal sensors.
As we will have a number of sensors collaborating together we in need to build a network and protocols to set communication done.
A WSN consists from hundreds to thousands of low cost sensor devices which could either have a fixed location or randomly deployed in an environment, they collaborate together to monitor this environment and send monitored data to a more powerful device which is the base station.
A single sensor node has a limited radio bandwidth transceiver for communication, a low computational capability processor, a small amount of memory and storage space for the code, and small un-chargeable batteries as an energy source.
Wireless sensor networks (WSNs) have recently attracted a lot of interest in the research community due to their use in a wide range of applications like industrial process control, security, surveillance, environmental sensing, health monitoring, etc. They are also used to support cost-effective sensing in situations where human observation or wired systems deployment can be inefficient, expensive, dangerous, or otherwise untenable.

called “Energy Harvesting Solutions”
-Inoculating a wireless network with some powerful capabilities sensor nodes can enhance the overall network's performance. In such situations the network will consist of two different types of nodes: a powerful high end sensors and weak low end sensors. This use of different sensors with different sensing and transmission capabilities leads to a heterogeneous WSN. One of the advantages of this heterogeneity is the assurance of network's coverage by using a small number of nodes rather than adding a larger number of weak nodes [20].
-There are two main distribution strategies defined in WSN: the structured (pre-deterministic) distribution and the randomized distribution. the structured (pre-deterministic) distribution provide full area coverage, where each sensor node is covering a predefined area.
-throwing sensor nodes from an airplane to a hostile environment. The coverage and connectivity performance in such a situation is dependent on the density of sensor nodes and their communication bandwidth.
the reliability of wireless sensor networks (WSN) is affected by faults that may occur due to various reasons such as energy exhaustion, hardware failure, communication link errors, malicious attack, or environmental hazards (e.g. fire or flood). Therefore, fault tolerance is one of the critical issues in WSNs, which is the ability of a system to deliver a desired level of functionality in the presence of faults [29]. The routing protocol has to have strategies for detecting happened faults within a network and enables that network to recover from these faults to continue its operations [30].
-the use of wireless sensor networks has become pervasive especially in hostile or harsh environments. Therefore, wireless sensor networks introduce additional security challenges for protocols designers. These security mechanisms should require less computational power and memory because of the constrained resources of the sensor node

When we talk about WSN we talk about isolated systems, that only accessible by the authorized peoples.
The idea of IoT is to plant all these isolated systems into a big integrated system.
Through given access to others (freely or paid). So they can build other applications and services over it.
Big Market
As the Internet of Things generates billions of data points that need to be stored, processed and analyzed, vendors competing in the data center hardware, software and service markets need to address this phenomenon with precise product, sales and marketing strategies.
Processing large quantities of IoT data in real time will increase as a proportion of workloads of data centers, leaving providers facing new security, capacity and analytics challenges

Data Center Network
The magnitude of network connections and data associated with the IoT will accelerate a distributed data center management approach that calls for providers to offer efficient system management platforms
The rapid growth of data will force data center vendors to include IoT-aware infrastructure and capacity management platforms in their product offerings
To conclude the IoT is one of the key drivers to the future internet.
The future internet is to convert the current internet into a new one that can serve all things.
