Your term paper should investigate the behaviour of devices in a wireless network. To

obtain a topic that is suitable for investigation, please pick one or two parameters from

the list below, or add own suggestions:

 number, distance, position of nodes

 type and size of interface queues

 number, destination, type of traffic flows

 number and size of data units in a flow

 directionality of the flow(s)

 routing protocol in use

 transport-layer protocol in use

Then pick one or two possible results to be investigated from the list below, or add own

suggestions:

 reachability of nodes

 success rate of transmission

 bytes transmitted per unit of time

 delay and jitter in a traffic flow

 duration of transmission setup (time before first data unit is transmitted)

 handover properties

The data field consists of: 20 Byte IP-Header | 20 Byte TCP-Header | 1000 Byte Transport data. At which places of the frame and with how many Byte one can find: Layer2-PDU, Layer3-PDU, Layer4-PDU, Layer3-SDU, Layer2-PCI?
