Background: Privacy-enhancing techniques are developed in order to provide strong protection to cyberspace. These techniques aim to allow users to keep their identities hidden during the communication when they are sending an email, making payments online, browsing the Web, or posting to newsgroups. MixNet is the most practical solution for concealing identities of message and sender’s identities. Objective: It provides the Read More

The immense growth of information has led to the wide usage of recommender systems for retrieving relevant information. One of the widely used methods for recommendation is collaborative filtering. However, such methods suffer from two problems, scalability and sparsity. In the proposed research, the two issues of collaborative filtering are addressed and a cluster-based recommender system is proposed. For the identific Read More

The efficient use of energy consumption in WSNETs is one of the most promising areas for researchers. In such networks, a considerable amount of bandwidth and energy is wasted for sensing the communication over the common channels. To recognise these complications, WSNETs offers dynamic allocation of the spectrum to optimise the bandwidth utilization. The S-MAC protocol which is based upon Time Division Multiple Read More
