Abstract
The spread of wireless networks and growing proliferation of mobile devices require the development
of mobility control mechanisms to support the different demands of traffic in different
network conditions. A major obstacle to developing this kind of technology is the complexity
involved in handling all the information about the large number of Moving Objects (MO), as
well as the entire signaling overhead required to manage these procedures in the network. Despite
several initiatives have been proposed by the scientific community to address this issue they
have not proved to be effective since they depend on the particular request of the MO that is responsible
for triggering the mobility process. Moreover, they are often only guided by wireless
medium statistics, such as Received Signal Strength Indicator (RSSI) of the candidate Point of
Attachment (PoA). Thus, this work seeks to develop, evaluate and validate a sophisticated communication
infrastructure for Wireless Networking for Moving Objects (WiNeMO) systems by
making use of the flexibility provided by the Software-Defined Networking (SDN) paradigm,
where network functions are easily and efficiently deployed by integrating OpenFlow and IEEE
802.21 standards. For purposes of benchmarking, the analysis was conducted in the control and
data planes aspects, which demonstrate that the proposal significantly outperforms typical IPbased
SDN and QoS-enabled capabilities, by allowing the network to handle the multimedia
traffic with optimal Quality of Service (QoS) transport and acceptable Quality of Experience
(QoE) over time.
