For the importance of human deployment of sensor nodes in WSN application

presents an approach named Easidesign which is used to get an optimal deployment of sensor nodes. Targeting to solve the scalability problem when use initial ant based approach to apply to sensor node deployment

the greedy scheme

additional pheromone evaporation methods were used. The most attractive ability of Easidesign is that it not only consider the different sink position but also guarantee the wholly connectivity between sink node and deployed sensor nodes. The algorithms key choice and pa-rameters setting to meet different practical requirements for certain applications are also studied through largely simulations. Simulation results show that the proposed approach has significant advantage over practical deployment of sensor networks compared with existing works.
