The document discusses Bluetooth technology and its connection states. Bluetooth allows digital devices to easily transfer files at high speed using a wireless connection. There are two main connection states for Bluetooth - active states where data can be transmitted from master to slave devices, and low power states where devices can enter a hold mode to connect to multiple networks or manage transmissions. The document also provides an introduction to wireless ad-hoc networks, which do not rely on existing infrastructure like routers and can operate in a distributed manner without single points of failure.

2. Definition:- Bluetooth refers to a wireless
technology which allows digital devices to
easily transfer files at high speed.
Bluetooth is common in many portable devices
such as laptop , PDAs ,mobile phones and
tablets.

3. CONNECTION STATES:-
 A) Active States :
Connected state : It shows maser
Connected with slave.
Transmit Data state: It shows Transmitted
Data from maser to slave
 B) Low Power States :
 HOLD mode: The HOLD is used when
connecting several piconets or managing a

4. Introduction:- A wireless ad-hoc
network(WANET) or MANET(mobile ad hoc
network) is a decentralized type of wireless
network.
The network is a ad-hoc because it does not rely
on a pre-existing infrastructure , such as router
in wired networks or access points in managed
wireless network.

6.  Highly performing network
 No expensive infrastructure must be installed
 Use of unlicensed of information around
sender
 No single point of failure

7.  No central entities=> operation in completely
distributed manner.
 Network function must have high degree of
adaptability.
 All network entities may be mobile => very
dynamic topology.
