Pamvotis - IEEE 802.11 WLAN Simulator

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 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 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 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).
• 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.
