%X Considering the wireless sensor network isn't uniformly distributed,and energy consumption for each node can't be balanced,even some nodes are captured or compromise to send forged data and so on,this paper proposed a trust model for sparse network based on beta distribution.After the characteristic of the sparse network had been fully taken into account,then each node's trust value could be easily computed and updated in cycle by the beta density function.Simulation results and analysis show that this trus...
