Outline of Final Research Achievements

We conducted theoretical research aimed at enhancing disaster resistance and improving the convenience of mobile communications by the collaboration between communication and power networks. For the former, we proposed a geographical network design method for communication networks to maximize disaster resistance, including the risk of communication interruption due to power outages during the expansion or establishment of communication networks, by obtaining geographical information of the power grid. For the latter, we modeled and evaluated the performance of microwave wireless power transmission. Specifically, we proposed a model that accurately represents the nonlinear characteristics of rectifiers and is useful in application of Stochastic Geometry. Based on this, we theoretically demonstrated the feasibility of implementing a network where wireless power transmission is performed between devices, effectively avoiding the need for charging.
