Abstract: This paper investigates the energy hole problem in WSN and proposes a new way to solve it. Based on coronas model, a statement of the dynamic longest-shortest coronas lifetime problem is presented and the mathematical model is constructed. It proposes an Immunity Clone(IC)-based energy-hole avoidance algorithm, which helps to prolong the lifetime of the network by searching for best coronas width and approximate optimal transmission range list. Simulation results show this algorthm balances the energy depletion and improves the network lifetime effectively.
