In this paper, an algorithm based on ladder diffusion and ACO [5,6] is proposed to solve the power consumption and transmission routing problems in wireless sensor networks. The proposed ladder diffusion algorithm is employed to route paths for data relay and transmission in wireless sensor networks, reducing both power consumption and processing time to(More)
In timetable scheduling problems, examination subjects must be slotted to certain times that satisfy several of constraints. They are NP-completeness problems, which usually lead to satisfactory but suboptimal solutions. As PSO has many successful applications in continuous optimization problems, the main contribution of this paper is to utilize PSO to(More)
In this paper, a Reduce Identical Composite Event Transmission (RICET) algorithm is proposed to solve the problem of detecting composite events in wireless sensor networks. The RICET algorithm extends the traditional data aggregation algorithm to detect composite events, and this algorithm can eliminate redundant transmission and save power consumption,(More)
The attack detection and information security for computer network become popular topics for many researchers in recent years. In this paper, the PCAICA method for attack and intrusion detection is proposed. According to the experimental result, the proposed method performs higher correct ratio on recognition than the PCA.
This paper presents a scalable digital learning system that can store and provide Web access to digital contents from voluntaries, teachers, and institutions that lack resources or expertise to offer classes over the Internet. We use the server-cluster architecture as a way to create scalable and highly available solutions. However, hosting a variety of(More)
