DIMSUMnet Scalable Spectrum Server


Description:

 The DIMSUMnet  spectrum server is a scalable implementation of the spectrum server implemented  using Java 1.6 SDK and the OpenMap. Currently, it runs on a Dell Poweredge 2950  server with 2 quad-core CPUs and 8 GB memory. The implementation supports multiple virtual brokers or a single broker on a single machine. Each (virtual) broker can be designated to handle a single geo-graphically contiguous area or multiple non-overlapping areas. The broker implements a spectrum leasing protocol and supports connections from Radio Access Network Managers (RANMANs). Each RANMAN connects to the broker over a TCP connection. The leasing protocol  implements the basic command set: (Register-RANMAN, Authenticate-RANMAN, Register-BS, -Alloc-Demand, Interrupt-Demand)
