Abstract—To improve network and mobility management in the Software-Defined Wireless Network (SDWN), the Locator/Identifier Separation Protocol (LISP) was integrated into the SDWN Controller, which originally controls and manages the OpenFlow routers in an SDWN. In this paper, we propose mathematical models of MIP, HMIP, LISP, the LISP Controller, and LISP-SDWN in order to evaluate the operation cost as a performance comparison analysis. The reference network architecture consists of wireless mobile networks, an operator network, and a public network. The five protocols have their own control messages with different sizes and operation procedures; therefore, the location management cost of one protocol differs from those of others when a mobile node moves from one subnetwork to another subnetwork. Some of them have a longer transmission path, which leads to a higher operation cost. The five protocols are evaluated through two communication scenarios: intra-SDWN communication and inter-SDWN communication. We evaluate the operation costs of LISP, the LISP Controller, LISP-SDWN, HMIP, and MIP based on mathematical models. A comparison of all of these operation costs indicates that the proposed LISP-SDWN is scalable in different communication scenarios and has the lowest cost for updating location information.
