On one hand, where the authors are seeing and experiencing the dilated technologies, the retrospective of the past is giving the researchers a new area to learn and pioneer new dimensions of the same challenges. Wired sensor networks had been a great source of getting the information about a specific object. But with incremental challenges that were posed to the researchers, wireless sensor networks were developed so that the impugnation that had become drawbacks of the wired network system could be dealt with. The upcoming of the wireless sensor network indeed brought with it many advantageous characteristic features, but there were also some vulnerabilities that crept in along with this great development.
