Node deployment is an important issue in Wireless Sensor Networks (WSNs). Sensor nodes should be efficiently deployed in a predetermined region in a low-cost and high coverage-quality manner. Localization methods based on mobile anchor nodes have been proposed for assisting the mobile nodes to determine their locations; none of these methods attempt to optimize the trajectory of the mobile anchor node. Route planning scheme, ensures that all of the mobile node can determine their locations. One of the main active attacks is black hole attack, it is a denial of service attack and it drops entire incoming packets between one source to destination.
