Abstract: An ad-hoc wireless network consist of a set of mobile nodes i.e. hosts that are connected by wireless links. The network topology (the physical connectivity of the communication network may keep changing randomly. routing protocols that find a path to be followed by data packets from the source node to a destination node used traditional wired networks cannot be directly applied in ad hoc wireless networks due to their highly dynamic topology ,absence of established infrastructure for the centralized administration .In this paper, have to studied about the proposed routing protocol with fuzzy system and their different parameter. The main purpose of this paper is to provide with latest implementation in different routing protocol with fuzzy system.

Abstract: Digital watermarking is emerging as effective technique to protect copyrights. The propose paper present a novel technique to protect digital data by embedding encrypted watermark. In this technique discrete wavelet transform is used to embed the watermark image. Each pixel value is encrypted by using stream cipher and the key used is same for encryption and decryption. Key security is essential to protect digital data from unauthorized access. Experimental results verify that the proposed technique performs better and it can withstand compression attack.
