On minimizing coding operations in network coding based multicast: an evolutionary algorithm

An improved quantum-inspired evolutionary algorithm for coding resource optimization based network coding multicast scheme

This paper investigates how to minimize the required coding resources in network-coding-based multicast scenarios. An evolutionary algorithm (MEQEA) is proposed to address the above problem. Based on quantum-inspired evolutionary algorithm (QEA), MEQEA introduces multi-granularity evolution mechanism which allows different chromosomes, at each generation, to have different rotation angle step v...

On Minimizing Network Coding Resources: An Evolutionary Approach

Abstract— We consider the problem of minimizing the resources used for network coding while achieving the desired throughput in a multicast scenario. Since this problem is NPhard, we seek a method for quickly finding sufficiently good solutions. To this end, we take an evolutionary approach based on a genetic algorithm that works in an algebraic framework, combined with randomized polynomial id...

On Minimizing Multicast Completion Delay for Instantly Decodable Network Coding

In this paper, we consider the problem of minimizing the mean completion delay in wireless multicast for instantly decodable network coding. We first formulate the problem as a stochastic shortest path (SSP) problem. Although finding the optimal selection policy using SSP is intractable, we use this formulation to draw the theoretical properties of efficient selection algorithms. Based on these...

An efficient secure channel coding scheme based on polar codes

In this paper, we propose a new framework for joint encryption encoding scheme based on polar codes, namely efficient and secure joint secret key encryption channel coding scheme. The issue of using new coding structure, i.e. polar codes in Rao-Nam (RN) like schemes is addressed. Cryptanalysis methods show that the proposed scheme has an acceptable level of security with a relatively smaller ke...
