Enhanced service discovery in Bluetooth

The rapid evolution and expansion of wireless-enabled environments have increased the need for sophisticated service discovery protocols (SDPs). Typically, service discovery involves a client, service provider, and lookup or directory server. The paper discusses Bluetooth (http://www.bluetooth.com) short-range wireless technology. The Bluetooth protocol stack includes specifications that define the SDP, RFCOMM (for cable replacement), the logical link control and adaptation protocol (L2CAP), a host controller interface (HCI), the link manager protocol (LMP), the base-band protocol, and a radio frequency (RF) protocol. The paper considers Bluetooth service discovery improvements with semantic matching.
