Magnetic resonant coupling based wireless energy transfer might be a contemporary technology for providing energy to a wireless detector network (WSN). But, charging detector nodes one at a time offers a major quality draw back. Recent technologies in magnetic resonant coupling show that multiple detector nodes is also charged at constant time. Throughout this paper, we have a tendency to tend to take advantage of this multi-node wireless energy transfer technology and examine whether or not or not the performance is best or not. We have a tendency to tend to suppose a wireless mobile charging vehicle (WMCV) that periodically moves at intervals a WSN and charging the detector nodes wirelessly. We have a tendency to tend to propose a cellular structure that divides the two-geometric area into adjacent twogeometric figure cells based on the charging vary of the WMCV. we have a tendency to tend to develop a correct improvement framework by optimizing traveling path, flow routing, charging time at each cell and minimizing the method quality. By activity this non linear optimization, we have a tendency to tend to develop academic degree best resolution for the routing path to charge multiple detector nodes in wireless manner 1. Introduction Wireless energy transfer could also be a good used technology [13] for charging the sensor nodes terribly very wireless sensor network. If the magnetic resonant coils operative at identical resonant frequency, incontestable that .
