. Wireless Sensor Networks (WSN) includes numerous sensor nodes that are connected to each other through the use of Wireless short distance links. The transfer of data between the individual nodes is found to be energy constrained and the energy-efficient protocol in WSNs is a huge requirement. In addition, the deployment of large numbers of sensor nodes increases the size of the network, which in turn increases the energy consumption rate. An efficient protocol is developed in this research that includes grid-based mobile communication network formation, efficient path selection through cluster head selection and data communication. In addition, multi-stage authentication is implemented to provide security from source node to destination node for the transfer of data. Sensor nodes life time is the most critical parameter. Many researches on this lifetime extension are motivated by LEACH scheme, which by allowing rotation of cluster head role among the sensor nodes tries to distribute the energy consumption over all nodes in the network. Selection of cluster head for such rotation greatly affects the energy efficiency of the network. Different communication protocols and algorithms are investigated to find ways to reduce power consumption. In this paper brief survey is taken from many proposals, which suggests different cluster head selection strategies and a global view is presented. Comparison of their costs of cluster head selection in different rounds, transmission method and other effects like cluster formation, distribution of cluster heads and creation of clusters shows a need of a combined strategy for better results.
