Abstract(s)
Wireless networks are gaining more and more importance in our world. Cellular phones with GPRS/UMTS, Wi-Fi, and WiMAX networks are very common these days, and they share a common feature: they require some
sort of backbone infrastructure in order to allow for packets from different communication peers to reach each other. For example, if someone makes a phone call, the conversation will always pass from the cell phone to the operators' infrastructure, and then to the receivers phone, even if they are both in the same building. Resources would be certainly saved if somehow the cell phones could connect directly to each other.
In an ad-hoc network, all the participants (also called nodes) can communicate directly with their neighbours. Two nodes are considered neighbours if their communication devices can reach each other. Nodes wanting to communicate to others that are not neighbours will simply send a message to another node which is located nearer the destination. As so, a centralised infrastructure to establish the connectivity is not required, since
each node will determine by itself to where it should forward its data. The specification IEEE 802.11 refers to this type of network as Independent Basic Service Set (IBSS). In this one first presents some background information about the previous simulator and about IEEE 802.11e. Then, the features of the new simulator, highlighting the modifications we performed, are described, followed by the presentation of the results of the initial simulations, Finally conclusions are drawn and suggestions for future work are presented.
