| Abstract: | According to the scenarios of fewer nodes with less mobility,a practical approach to Ad hoc based on Bluetooth is proposed,including the design of network routing,application framework and a distributed path discovery algorithm which is easily implemented in L2CAP(logical link control and adaptation protocol) layer of Bluetooth.In order to verify and test the approach,an experimental system is implemented.Combining with the test data,performances of Ad hoc based on Bluetooth is theoretically derived and comparatively analyzed in detail,including the analysis of linking time,bandwidth and average delay.It is concluded that this approach to Ad hoc based on Bluetooth is fit for multi-hop communication and text,voice and video communication can be well supported. |
