Abstract: A Wireless Sensor Network(WSN) consist of spatially dispersed ,dedicated sensing nodes for monitoring and recording various physical conditions of the environment, which later organize the collected data to a central location.WSN technology is gaining much important for its growing need for data collection & transmission in various day to day applications. A node is basically a sensor ,operated by battery, low cost device with limited computing, communication & storage capabilities which is deployed in hostile or inaccessible location in which node replacement or repair is impractical For deployment of network efficiently ,various key parameters are to be considered for evaluation in an application specific way. For the special structured network architecture deployment, efficient placement of nodes, QoS, life time maximization, delay tolerance are some important parameters to be taken care. This paper briefly gives an idea about different optimization algorithms used for the deployment of sensor nodes inconsideration with different factors and aspects, which provides a reliable WSN to conserve energy and life time of sensors.
