In order to improve the network coverage, this paper presents the research on wireless sensor network coverage based on improved particle swarm optimization algorithmfor wireless sensor nodes that are randomly deployed in a certain area. In this paper, we use the regional network coverage as the target objective function, and combine various improved particle swarm optimization algorithms to optimize...
RSA is a typical algorithm of public key cryptography algorithm, analyzing the reason of large prime numbers which is the factor of restricting thisalgorithm's safety, and giving the method of determining the large prime numbers. Design fitness function, crossover and mutation strategies which can be used in genetic algorithm. Finally design the algorithm of producing large prime numbers.
A novel Hybrid Clustering Algorithm (HCA) that incorporates the K-means into the canonical Immune Programming Algorithm (IPA) is proposed after analyzing the advantages and disadvantages of the classical k-means clustering algorithm in the paper. The theory analysis and experimental results show the algorithm not only avoids the local optima and is robust to initialization, but also increases the...
A new image encryption algorithm is proposed by combining the cat mapping and the standard mapping of conservative chaotic systems. The proposed algorithm first produces chaotic sequence by using the standard mapping; then the sequence is discretized. Two values, which are used as the parameters of the cat mapping to realize the scrambling encryption for images, are extracted. In the end, the alternative...
An algorithm for one-way hash function construction based on conservative chaotic system is proposed. The plaintext is divided into a group of message blocks by a fixed length and each message block is iterated some times through standard map. Both the iterations results of every round and the plaintext block determine the two initial values and the steps of iterations in next round. Some items of...
This paper first introduces negative selection algorithm of artificial immune system and non-dimension-parameter, and then designs the unit fault diagnosis system software based on artificial immune system by combining negative selection algorithm and non-dimension-parameter. The advanced nature, practicability, validity and correctness of the idea on software design are proofed by the experiment...
