摘要: With the development of wireless sensor network (WSN), design and maintenance WSN are still challenge in a large number nodes which constrained energy bandwidth. Thus, new solution is high altitude platforms (HAPs) that can be employed as relay order to reduce consumption because multi-hop transmission enlarge coverage range WSN. In this paper, novel heterogeneous system consisting HAP layer, layer mission proposed. system, we model deployment HAPs based on markov random field with maximum posteriori probability (MAP) framework, thus obtaining function HAPs. Then, potential game approach introduced analyze function, proves able achieve pure Nash equilibrium. addition, modified distributed learning algorithm called sequential spatial adaptive play presented solve proposed game. Finally, simulation results illustrate method equilibrium optimal
