Energy consumed unevenly will bring the production of hot spots. Hot spot will cause WSNs to divide some unconnected sub-networks and shorten the lifetime of WSNs. To tackle this problem, a load-balance mechanism is proposed based on minority game (MG) with dormancy strategy. This mechanism can cause the rich behaviors of cooperation , prolong lifetime of WSNs, and keep energy consumed evenly. This dormancy mechanism can save energy of nodes by keeping in sleep temperately .
