Software-defined networking (SDN) aims to provide open interfaces, such as OpenFlow protocol, that enable programmable flow-based network management. Meanwhile, OpenFlow-enabled switches provide rich statistical information for specific flows, tables, and ports which facilitates various network management tasks. However, current traffic monitoring techniques collecting statistics from existing flow...
In recent years, use of mobile robot acting as a data mule for collecting data in the wireless sensor network has become an important issue. This data collection problem of generating a path as short as possible for a data mule to gather all data from all of sensor nodes is known as a NP-hard problem named Traveling Salesman Problem with Neighborhoods (TSPN). We proposed a clustering-based genetic...
The problem of planning a path for minimizing the distance the mobile robot has to traverse to accomplish the task of gathering the data stored in a spatially distributed wireless sensor network is a kind of Traveling Salesman Problem with Neighborhoods (TSPN). We proposed a one-hop data-gathering scheme using clustering-based genetic algorithm (CBGA) that performs well: following the planned route,...
