Abstract:

Due to the original minimum exposure path (MEP) problem in wireless sensor network without considering the constrained conditions for paths in practice, a new MEP problem with the request along a part of the boundary of the special protection area (BPA-MEP) was put forwand. As unable to set up the corresponding graph model, the classic methods (such as grid-based method and Voronoi-based method) in solving MEP problem would no longer work to BPA-MEP problem. To solve BPA-MEP problem, a optimization model with constraints as highly nonlinear and higher dimensional problem was tailored and established and then taking the characteristic of the distribution of the sensor nodes, a hybrid artificial bee algo-rithm was proposed to solve this complex optimization model. The results of the proposed model and the designed algorithm, when implemented in many aspects, show that they can s A-MEP problem effectively.

Key words: wireless sensor networks, minimum exposure path, protect area, hybrid artificial bee algorithm
