There are several parameters based on which the performance of WSNs can be analyzed. Some of these parameters are as follows. There are various methods to improve the Network life time:

Node deployment technique: Given some sensor nodes that can be deterministically deployed, where to deploy them and how to schedule them so as to achieve the required target coverage level and increase the network lifetime. One of the basic requirement of node placement is to accomplish desired coverage and connectivity. NODE deployment is one of the most critical issues in wireless sensor networks (WSNs). Node deployment can be divided into continued-point based deployment and grid point based one. Due to specific advantages, the latter becomes necessary in a broad range of applications [1], [2]. The fundamental requirement of node placement is to achieve desired coverage and connectivity, where coverage is to guarantee that every point of interest (PoI) is monitored by at least one sensor, and connectivity is to ensure sufficient routing paths [3].
