Pamvotis is a Wireless LAN (WLAN) simulator tool for all the current physical layer extentions of the IEEE 802.11 Standard and for the IEEE 802.11e Draft for Quality of Service in WLANs.

The currently standardized physical layer extentions of IEEE 802.11 include IEEE 802.11a, IEEE 802.11b, and IEEE 802.11g, which are all supported by Pamvotis. Current version is Pamvotis 1.1.

Main features:

  • Support of data rate agility. This means that each node can work on its own data rate, depending on the distance from the receiver.
  • Support of the hidden terminal problem. Nodes can be configured to be in LOS or NLOS, in order the hidden terminal problem to be investigated.
  • Support of multiple sources on each node (new in Pamvotis 1.1).
  • Support of a variety of different traffic sources:
  • Generic (abstract) traffic source, that produces traffic the packet generation rate and packet size of which can obey different distributions (new in Pamvotis 1.1):
  • FTP traffic source, as described in 3GPP TR 25.892 V.6.0.0.
  • HTTP traffic source, as described in 3GPP TR 25.892 V.6.0.0.
  • Video traffic source, as described in 3GPP TR 25.892 V.6.0.0.
  • Support of absence / existence of non-ERP nodes. This advantage utilizes the option of the IEEE 802.11g protocol to adjust the network parameters depending if all nodes support IEEE 802.11g (absence of non-ERP nodes) or some nodes support only 802.11b or earlier (existence of non-ERP nodes).
  • Support of the new CTS-to-Self virtual carrier sense and protection mechanism: This means that a node can support RTS/CTS or the new (defined in IEEE 802.11g specification) CTS-to-Self virtual carrier sense mechanism for better network performance.
  • Support of all new physical layers of the IEEE 802.11g specification which include:
  • ERP-DSSS/CCK: Support of IEEE 802.11 data rates (1, 2 Mb/s) and IEEE 802.11b data rates (1, 2, 5.5 and 11 Mb/s).
  • ERP-OFDM: Support of all extended data rates defined in IEEE 802.11a and IEEE 802.11g (6, 9, 12, 18, 24, 36, 48, 54 Mb/s).
  • ERP-PBCC: Support of the extended data rates of 22Mb/s and 33Mb/s.
  • DSSS-OFDM: Support of the extended rates of the IEEE 802.11a with DSSS preamble and OFDM payload
  • Support of the IEEE 802.11e EDCA function for Quality of Service (QoS) and Service Differentiation in IEEE 802.11 WLANs.
  • Support of many statistic results, which show detailed information concerning the MAC layer performance. Those are: Throughput in bits and packets per second, utilization, media access delay, queuing delay, total packet delay, delay jitter, mean number of retransmission attempts and mean packet queue length.
  • Many functions (for developers), that help use Pamvotis as an embedded simulator effectively, like adding or removing sources and nodes at any time (new in Pamvotis 1.1).
  • Ability to simulate very long simulations, up to 50737 centuries, but it is not recommended to try it because you will probably never see the simulation results.
  • Very limited resource requirements, which allows operation in any PC.
  • Cross platform operation,meaning operation in any OS with Java Runtime Environment installed (Windows, Linux, Solaris, MacOS).
  • User friendly interface, which allows quick and easy simulation configurations.
  • Open source code, in order to implement your own protocols.
