And it’s an autonomous system in which mobile hosts connected by wireless links are free to be dynamically and sometimes acts as a router at the same time. With some restriction of wired communication wireless technology comes into the picture. The emphasis in this paper is concentrated on Mobile Ad- Hoc Networks. They can be set up anywhere without any need for external infrastructure (like wires or base stations). This can be a standard Wi-Fi connection, or another medium, such as a cellular or satellite transmission [1]. This paper includes working of some Proactive, Reactive and Hybrid protocols that make communication possible it ...

It occurs when an audio source and sink operate in full duplex mode; an example of this is a hands-free loudspeaker telephone. The signal interference caused by acoustic echo is distracting to both users and causes a reduction in the quality of the communication. This paper focuses on the use of adaptive filtering techniques to reduce this unwanted echo, thus increasing communication quality. Adaptive filters are a class of filters that iteratively alter their parameters in order to minimize a function of the difference between a desired target output and their output. In the case of acoustic echo in telecommunications, the optimal output is an echoed signal that accurately emulates the unwanted echo signal. This is then used to negate the echo in the return signal. This paper examines various techniques and algorithms of adaptive filtering, employing discrete signal processing in MATLAB.
