Adaptive filters are the major components in a digital Beam forming technique which can be utilized in implementing smart antennae which can adaptively change the direction of beam towards the user. This can be achieved with a feedback mechanism used in the filters named adaptive filters and the filter transfer function is implemented with an algorithm(More)
In Wireless Sensor Network (WSN), due to limited battery energy, reduction of energy consumption is a challenging issue. In a typical clustered WSN, decisions can be taken locally at (cluster level) as well as globally at a central Sink. Local decision making requires information exchange among neighbor clusters. In this work, a network coding based(More)
