| Popis: | 104 As a short-range and peer-to-peer wireless communication technology, Bluetooth low energy (BLE) receives lots of attentions recently. By enabling discover devices in the proximity, BLE could support various mobile Internet of Things (IoT) applications. Obviously, device discovery plays an essential role on the trade-off between number of devices discovered and energy consumption for a mobile IoT device. This paper subsequently proposes a smart device discovery mechanism, sDiscovery, to adaptively adjust scan window and scan interval according to the current status of the environment. In particular, we leverage the number of peers discovered more than once to make sure if the status of environment changes frequently. The scan window and scan interval for a mobile IoT device could be regulated accordingly. The simulation results show that sDiscovery outperforms the existing solution and conventional BLE mechanism from the perspective of power saving. Moreover, we verify the correctness of simulation model through experiments in TI CC2540 development board, where a prototype of the protocol is implemented. Our simulation results demonstrate that compared with conventional BLE discovery scheme, sDiscovery can save around 74 percent energy by paying the price of discovering a fewer number of peers. |
