چکیده
WSNs are a class of wireless ad hoc networks that are different from conventional networks (Heinzelman et al., 1999) by several reasons: its small footprint, its low cost design, and its nodes scarce resources such as: limited supply of energy, limited storing and computation power, low bandwidth and energy-conserving communication. These limitations prevent them from running sophisticated network protocols, and limit inter-nodes communication. However WSNs technology also offers a series of features described as advantages by Krishnamurthy et al. (2005), Shen et al. (2004), and Paavola (2007), where can be highlighted: the ability to capture online information directly from field devices, the reduction of deployment and maintenance costs, compared to wired connection infrastructure on heavy duty or isolated environments, the improvement on area visibility due to ABSTRACT
