摘要
Load-balance is an important issue in wireless sensor networks (WSNs), especially in WSNs with hierarchical structure. 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 . Simulation results show that the proposed strategy can efficiently enhance the lifetime of cluster and the lifetime of whole WSNs.
