| Abstract: | First,a direction adjustable sensing model is proposed.Then,a low redundancy coverage-enhancing algorithm is presented.Traditional coverage-enhancing algorithm based on fictitious force just shows the adjustment direction,and angle compensation is a fixed value.By presenting a relation model of fictitious force and angle compensation and changing the node ’ s angle compensation,this algorithm gets a higher adjustment efficiency.When one node enters the steady state,it judges whether it ’ s a superfluous node according to its surrounding nodes.If the answer is yes,we set shall it to a resting state,and make all nodes in one of its coverage-set to stopping adjusting.Simulation results show that FFLRCA can obviously raise the adjustment efficiency and solve the coverage-redundancy in network based on the same coverage. |
