hackers are from the noise. This Project describes a design of effective security for data communication by designing standard algorithm for encryption and decryption. R.F. is a PAN technology based on the IEEE 802.15.4 standard. Unlike Bluetooth or wireless USB devices‚ R.F. devices have the ability to form a mesh network between nodes. Meshing is a type of daisy chaining from one device to another. This technique allows the short range of an individual node to be expanded and multiplied‚ covering a
