SDN based Managed WiFi Application

The growing demand and the diverse traffic pattern of smart devices place an increasing strain on the wireless networks. Routing data among wireless routers becomes a challenging issue as traditional routing algorithms, which cannot fulfill the requirements of distributed communications in Smart Cities. The routing decisions are taken based on local knowledge of a wireless router about each of its neighbors to reflect a partial visibility of the network. Such a local visibility limits the ability of managing the huge number of wireless smart devices in Smart Cities. An attractive alternative is the Software Defined Networking (SDN), which offers a centralized view of the entire network by refactoring the wireless protocols into control and forwarding decisions. However, many challenges must first be overcome to realize this potential. In this paper we describe: OpenSDWN Architecture, Programmable Datapath, Wireless Monitoring using SDN-WIFI solution.
