Abstract. Bluetooth specification still has open issues, including the intra and interpiconet scheduling topics. This paper proposes an interpiconet scheduling algorithm, referred to as AISA (Adaptive Interpiconet Scheduling Algorithm). AISA is characterized by: its adaptability to varying network traffic conditions; and its ability to optimize specific performance metrics via parametrization. Both features enable it to be employed in a variety of scenarios with improved performance showed by the simulation results.

“…As an augmented scene is viewed in real-time, it is important to give the illusion of an instantaneous modification of the view. In particular, the paper applies low-delay control to an IEEE 802.15.1, Bluetooth [8], real-time video stream in the face of sensor and external data cross traffic. Bluetooth is a low-power system [5] with typical currents of 1-35 mA, compared to IEEE 802.11's (Wi-Fi) 100-350 mA, though with shorter range of 10 m for class 1 devices as opposed to 100 m. In the AR system modelled, a video camcorder captures the surrounding scene, which is subsequently played back to the wearer with the addition of superimposed information.…”

A Personal Area Network (PAN) is a feature of an Augmented Reality system, transmitting modified video for real-time display. In the paper, low-delay communication of encoded video over a Bluetooth wireless PAN is achieved by a combination of dynamic packetisation of video slices together with centralised and predictive rate control. The result is minimized packet delay (below 0.05 s) and highquality 40 dB video, with packet loss limited to 4% from RF noise.

“…Bluetooth [1] is a promising low cost and low power wireless technology, which enables portable devices to form short-range wireless ad hoc networks based on a frequency hopping physical layer. Bluetooth operates in the unlicensed 2.4GHz ISM band, with the frequency hopping technique to alleviate the effects of the interference.…”

Abstract-The paper proposes a strategy for each Bluetooth device selecting proper communication neighbors and assigning proper label, hence all nodes together form a hierarchical self-routing Bluetooth networks. Both the scatternet formation and routing protocols do not require any geometric information, and the final network topology has the following attractive properties: (1) the diameter of the scatternet is O(log(n)) and the backbone is a hop spanner; (2) the degree of each master node is bounded by a constant 7; (3) the number of piconets is close to optimal; (4) each cluster has self-routing property. Moreover, the network topology can be maintained dynamically and locally with low communication cost, and the message delivery is guaranteed even during structure updating in clusters. The network supports efficient IP-based routing through Distributed Hash Tables(DHTs). The actual routing performance on the structure is evaluated through extensive simulations, the result shows the average communication hops are indeed around log(n).
