| The current routine scheme implemented for wireless systems is based on the network architecture developed for wire-line networks. It does not consider the physical characteristics of the wireless medium for optimizing network performance. The emergence of Ultra wideband, a high frequency transmission technology providing high transmission rates, has implied we reconsider the current network architecture. The salient feature of ultra wideband is its ability to measure the physical distance between the transmitter receiver pair. We develop a cross layered architecture which would utilize the physical layer parameters to reduce discontinuities for a mobile node. The positional information is made available to the routing layer for generating an alternate path to the mobile node. This improves the network connectivity for the mobile node and reduces its power consumption due to the absence of route requests. |
