Interference and power control in ad hoc wireless networks

This thesis looks at the problem of interference when Power Control is applied to maximize the network capacity. In ad hoc networks, the RTS/CTS dialog or virtual carrier sensing is less effective since a transmission takes place over three ranges: interference range, carrier sense range and transmission range. The values of interference range do not interrupt a transmission if it is close to noise floor, however the carrier sense range is capable of disrupting a transmission. Location, packet size and the traffic must be considered as important parameters in power control protocols. The majority of the work is focused at the physical and link layers
