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

Usage diagram:

The following diagram shows usage relationships between modules, networks and channels. Unresolved module (and channel) types are missing from the diagram. Click here to see the full picture.

Used in compound modules:

If a module type shows up more than once, that means it has been defined in more than one NED file.

BaseStationHost

The BaseStationHost is a compound module that implements a test base station. The test base station contains the PollApplLayer which periodically polls all clients in the network.

Parameters:

Name	Type	Description
debug	bool	debug switch
numClients	numeric const	number of clients in the network
headerLength	numeric const	length of the application message header (in bits)
pollTimeout	numeric const	timeout for poll messages
broadcastInterval	numeric const	time between bradcast messages in seconds

Gates:

Name	Direction	Description
lowergateIn	input	from network layer
lowerControlIn	input
lowergateOut	output	to network layer
