Abstract:Since the node’s energy dissipation model is not taken in to account in the traditional coverage models,based on the collaboration coverage model, the energy efficient hierarchical collaboration coverage model isproposed, which can evenly balance the energy dissipation among different layers in the target monitor area. Thispaper solves two specific problems in the ant colony solution. They are a formula of heuristic factor calculating forthe model and the upper and lower bounds of node numbers. Simulations in Matlab show that the proposed model ismore suitable for practical deployment which can evidently prolong the network lifetime.
