Abstract: Existing optimization algorithms of wireless multimedia sensor networks (WMSMs) are easy to fall into local optimal solutions. The cuckoo search algorithm, by using a long distance search, can jump out of local optima effectively. This algorithm is based on the 3D perception model. The ratio of coverage is improved by introducing elite mechanism, multi-dimensional optimization and learning-feedback strategy to optimize the angle of rotation and reduce overlap. The improved cuckoo search made the first attempt to optimize the network coverage in MSNs. Finally, the simulation results show that the ratio of coverage is improved by the proposed algorithm.
