Future Wireless Networks (FWNs) are expected to be a convergence of different kinds of wireless technologies, such as cellular technologies, wireless local area networks (WLANs), wireless metropolitan area networks, wireless sensor networks, and traditional wired networks. Although users and/or customers will be oblivious to the specific underlying network being used by their applications, the networks should be able to provide the resource (bandwidth) with guaranteed quality of service (QoS). The users should be able to move seamlessly among different networking technologies, e.g., among Ethernet, WLANs, WiMAX, and 2G/3G/4G, with stringent QoS requirements. A challenge of FWNs is also to optimize the dynamic selection of the best, or N best, interfaces of multi-interface devices, in accordance with user and device constraints, such as power consumption, user charges, and application specific QoS requirements (e.g., delay, delay jitter, and throughput). Another challenge is the scalability of handling the communication of billions of mobile devices in the united ubiquitous network framework of FWNs. A common well-known networking protocol used in wired/wireless networks is the Internet Protocol (IP). IP will be potentially adopted as the common networking protocol for diverse networking technologies including the next generation of cellular networks citations of System Architecture Evolution (SAE). However, a traditional IP architecture has several known challenges, such as mobility, multihoming, routing scalability, location privacy, path preference selection, etc. One of the greatest problems preventing the network from overcoming these challenges is that the IP address is contextually overloaded, both as locators and identifiers. As a result, in this paper, we describe the issues of all IP-wireless networks, and survey recent proposals focusing on IP overloading that can be applied to FWNs.
