In this paper a technique is offered for improving the security of data transmission. In today's technical world the prime objective of wireless communication is to make the transmission not only clear, noise free and time efficient but also to make it well secure from unauthorized interceptors. Frequency hopping is a technique used for this purpose in which the random sequence is used to add with each hop of frequency which is used to change randomly at every instant. There was a drawback that if the attacker comes to know the sequence code for selecting the carrier frequencies, than the integrity of the authors' information could be loss.
