Abstract:
In recent years we have seen a fast change in the networking industry:
leading by the Software Defined Networking (SDN) paradigm that separates
the control plane from the data plane to enable programmability and
centralized control of the network infrastructure, the SDN design not
only simplifies the network management but also accelerates the innovation
speed of deploying advanced network applications. Meanwhile, the landscape
of the wireless and mobile industry is changing dramatically as well.
Given the advance of wireless technologies such as 4G and WiFi offering
a pervasive Internet access, the traffic growth from the smartphone-alike
devices has placed an increasing strain on the mobile network infrastructure
and infringed the profit. Since the demand is increasing together with
the growth of mobile users, the incumbent legacy infrastructure is already
calling for an upgrade to overcome its existing limitations in terms of
network management and security. In this paper, we advocate that the way
forward is to integrate SDN and fully utilize its feature to solve the
problem. As the security issue has raise serious concern in the networking
community recently, we focus on the security aspect and investigate
how to enhance the security with SDN for the wireless mobile networks.
