This book aims to fill a growing need in the research community for a reference that describes the state-of-the-art in securing group communications. It focuses on tailoring the security solution to the underlying network architecture (such as the wireless cellular network or the ad hoc/sensor network), or to the application using the security methods (such as multimedia multicasts).We now address the more realistic scenario where users have different costs as well as budget constraints. We are therefore interested in the problem of minimizing the total cost of the length assignments lj for the weights wj given the budget constraint lj ac bj. ... One efficient algorithm for finding the optimal Huffman code under the maximum codeword length constraint is presented in , which is basedanbsp;...
