In this paper, we propose an audio speaker handover system that is designed to enable automatic selection and control of most suitable audio output devices. For smooth device handover, we also propose a modified received signal strength (RSS) based distance estimation method that limits the transmit power control function. From the experiments, we will show in this paper that the proposed audio device...
The increasing number of sensors deployed in cars calls for new design approaches in intra-vehicle electronic control unit (ECU) networks. ZigBee wireless sensor networks are seen as a good candidate technology, since they can provide high-performance short-range communication with low power consumption, as well as mesh networking capabilities. One of the main questions to answer before adoption of...
Wireless networks are becoming increasingly popular. These wireless solutions range from personal networks (e.g. Bluetooth), through local (e.g. WiFi) and metropolitan area networks (e.g. WiMax) up to the cellular networks that offer the coverage almost everywhere. As the number of different wireless technologies grows, a unified and standardized mobility support algorithm for heterogeneous networks...
Adaptive ARQ is applied to a wireless network, altering retransmission policy according to content importance. By a video deadline-aware buffer discard policy, repeated transmission of expired packets and buffer overflow are mitigated, helping to maintain video quality. Multiple deadlines are applied according to picture type. The combined policy is demonstrated for a bluetooth piconet achieving fast...
