Wireless sensor networks (WSN) are a technology that has been demanding, emerging and popular in recent decades. Since WSN has many areas of application, it also presented the researchers with several challenges. Even though there are many energy conservation techniques available, energy conservation in the WSNs has become a very big task for designers. Security has also become a huge concern because of the inclusion of the wireless channel in the WSN. The biggest task in recent trends is to secure the data, maintaining confidentiality without hampering coverage. Therefore, a mechanism is needed to overcome all these problems in order to improve the network lifetime with energy conservation, data security, reliability, and improvement of the network lifetime. With enhancement of energy efficiency, data protection, t, and without hindering the coverage, network life time will be increased. This paper discusses the different approaches used for the above problems and also offers a brief overview of some of the protocols used to achieve protection and conservation of energy. The other researchers will further use these results to make the WSN more safe and increase energy efficiency by selecting the best mechanism.

Energy conservation. Security, challenge.
