The integration of mobile communications together with computer internet network is the main focus of Information technology industry. The user anticipations are swelling with regard to a huge range of services and applications with unalike point of quality of service (QoS), which is related to bandwidth, throughput, energy and delay. LAS-CDMA (Large Area Synchronized Code Division Multiple Access) covers global area, enables high-speed data transmission and increases voice capacity. MC-CDMA (MultiCarrier Code Division Multiple Access) is designed for running on wide area, called macro cell. The LMDS (Local Multipoint Distribution System) designed for micro cell, enables wireless broadband technology used to carry voice, data and video services in 25GHz. 4G network integrates all access networks resulting in overlap coverage area. This may cause network resources wasted in the overlap coverage area. Therefore, it is necessary to propose a solution for this situation through utilizing multi network radio frequencies. This paper focuses on Network Resource Management and Energy efficiency through Multi Network Data Path; considering mobility between the nodes. The Network Resource Management Algorithm is designed using bandwidth management which includes bandwidth monitoring and selection. The performance is evaluated by assigning different paths to the mobile nodes. Simulation results shows that Network Resource Management Algorithm improves the energy efficiency by 23%. This algorithm considers movement pattern of the mobile nodes which varies the buffer size by 0.1%. Keywords—Multi-network, 4G, Mobile Multimedia
