Abstract
Bluetooth works on a Master/Slave model supporting a 1Mbps nominal bandwidth. While this communication model is simple, it incurs longer delay due to sub-optimal packet forwarding and dual allocation of resources for slave-to-slave communication via the master. It also cannot serve demands exceeding this 1Mbps capacity. Group communication can only be supported by inefficient methods like multiple unicasts or a piconet-wide broadcast. We overcome these limitations by using Traffic Engineering concepts, providing QoS, admission control, maximal channel utilization and multi-device conversation with minimal interference. To overcome these problems we introduce four novel proactive techniques- Pseudo-Role-Switching(PRS), Dynamic-Slot-Allocation(DSA), Multi-Device Conversation(MDC) and Pseudo-PaRtitioning(PPR). We first achieve the maximum possible throughput using PRS and DSA and then dynamically partition the piconets using PPR. DSA also supports multicast-like communication. Through extensive simulations, we observe that by combining PRS or DSA with PPR, Bluetooth’s throughput, delay and scalability is enhanced while interference and overhead is minimized.
