// Application layer to test centralized scenarios
//
// Application layer for a base station in a centralized WLAN-like network
// Every 'broadcastInterval' it broadcasts a ping message to determine the 
// reachable clients. Afterwards it polls all reachable clients in a round-robin
// manner, where 'pollTimeout' is the reply timeout for the clients
