摘要：What is the most important problem in sensor network designing is how to place sensors. Their arrangement can be designed carefully in order to build a surveillance system for optimization is very effective to achieve the desired design goals. With using the appropriate nodes placement, we can improve parameters of networks such as coverage, communication, energy consumption and longevity and optimize system performance according to our specified budget. Since the available resources an d system settings depend on node placement and determine network performance range, wireless sensor networks have been regarded as crucial issues. In this survey, convex hull algorithm has been used to place nodes properly. The goal of our proposed method is to optimize the number of sensors, low power consumption and determine node placement to support a distributed sens or network in asymmetric area. As many areas in these common methods which do not require sensor placements have also been covered, the number of sensors in the desired area is being increased and subsequently it leads to energy consumption upsurge.
