Simple Module ConnectionManager

Package: org.mixim.base.connectionManager
File: base/connectionManager/ConnectionManager.ned

Module to control all connection related stuff

The central module that coordinates the connections between all nodes, and handles dynamic gate creation. ConnectionManager therefore periodically communicates with the mobility module and ChannelAccess.

The four parameters pMax, sat, alpha, and carrierFrequency are used to calculate the interference distance between nodes. The values used here in ConnectionManager are used to calculate the upper bound, i.e. they can be redifined in the analogue models, but never such that the maximal interference distance is exeeded.

Networks:

AnalogueModels (network)	This example shows how to use AnalogueModels.
BaseMoBANNetwork (network)	This network is exactly the same as baseNetwork existing among the examples of MiXiM, but the desired number of MoBAN coordinator modules have been added. Some nodes of type BaseNode use MoBANLocal module as their mobility module. Then those nodes will be considered as WBAN nodes. Those node have a parameter named "coordinatorIndex" that determines to which WBAN (coordinator) the node belongs.
BaseNetwork (network)	This example shows the basic structure of an network using MiXiM.
BMAC (network)	(no description)
CSMAMac (network)	This example shows how to use MiXiMs CSMA protocol implementation.
ieee802154a (network)	This example illustrates the use of the IEEE 802.15.4A UWB-IR simulation model implemented in MiXiM. The omnetpp.ini files comprises two scenarios. Both scenarios involve only two hosts.
ieee802154Narrow (network)	This example shows how to use MiXiMs implementation of the ieee802154 narrow band protocol. It also provides an example on using the global blackboard provided by BaseWorldUtility.
LMAC (network)	(no description)
Mac80211 (network)	This example shows how to use MiXiMs 802.11 protocol implementation.
MultiConnectionManager (network)	This example shows how to use multiple ConnectionManagers in your simulation.
WSNRouting (network)	This example shows how to simulate wireless sensor networks. Three different routing protocols are considered, for different traffic types: convergecast, with Wiseroute; network-level broadcast, with flooding; and probabilistic broadcast.

Parameters:

Name	Type	Default value	Description
coreDebug	bool		debug switch for core framework
sendDirect	bool		send directly to the node or create separate gates for every connection
pMax	double		maximum sending power used for this network [mW]
sat	double		minimum signal attenuation threshold [dBm]
alpha	double		minimum path loss coefficient
carrierFrequency	double		minimum carrier frequency of the channel [Hz]
drawMaxIntfDist	bool	false	should the maximum interference distance be displayed for each node?
