The ease deployment of Wireless sensor networks (WSNs) in the harsh and hard

environment possesses a paved because the way it is. They are formed by sensor nodes which are responsible for examining environmental and corporal conditions to perform data processing. In this chapter, the manner of deployment will be presented, and how they communicate over a wireless link to unite the necessities of

Wireless sensor networks considered as a special type of ad hoc network, where the fixed communication infrastructure and centralized administration are absent. Here, the nodes play both the role of hosts and routers [1, 2]. These Nodes can be deployed randomly or regularly in a WSN environment. There is a concession between these in terms of the number of nodes, deployment time, deployment cost, and feasibility of the placement scheme. They are smart and capable of accomplishing three complementary tasks: the reading of a physical quantity, the possible processing of this information, and the communication with other sensors [3]. Coverage guarantees the monitoring area is covered by at least one sensor node while connectivity is needed to make sure that every sensor node is precisely connected to the sink node or indirectly connected to the sink node by any other sensor nodes. In addition to their deployment fashion for an application, they form a wireless sensor network [4]. Its purpose is to monitor a geographic area, and sometimes to operate on it. Examples include a forest fire detector network, or abridging strength monitoring network after an earthquake [5, 6]. The network can include a large number of nodes (thousands). Though, their flexibility besides their ease deployment in unprotected environments, have allowed in improving people's living. Also, the capacity of the sensor on gathering information from surrounding is very helpful for a human being to make information accessible by the user [7]. In addition to their flexibility. Nowadays, they are also used in the construction of a smart home system. Moreover, Routing protocol
