In recent years have realized that the current system of generation, transmission and distribution of electric power has become traditional and outdated to meet the entire demand. With that there was a strong growth in research on a concept with new technologies to modernize or build the electric power grid in its aspects of infrastructure, availability, sustainability and reliability. This new concept that is the smart grid that proposes a technology based on automation, communication, monitoring and control of the power grid, which allows implementation of control strategies and grid optimization efficiently before the currently used. The technology applied in smart grid includes many systems. Among these are communication topology systems, circuits and electronic interfaces, which makes it difficult to build a real scenario to carry out studies and researches of which system is best suited for applications in the smart grid. The equipment is very expensive and depending on the extent and amount of devices that will be deployed, make impossible the achievements in the field setting. To remedy these problems are used simulation software that are convenient tools in these cases and commonly employed in the area of research, to conduct the analysis and performance of a system. A communication network involving critical applications, such as electric power transmission and distribution must be highly reliable, extremely safe and resilient. To perform analyses of performance of a wireless communication network to be used in smart grid applications with desirable results, you need to perform simulations in order to anticipate any eventuality of possible failures. Of all existing simulators as indicated was the NS-2, a discrete event simulator for open source networks that facilitates the creation of communication networks scenarios, taking into account the protocols involved in wired or wireless technologies. This software supports the ...
