Abstract Communication via email has expanded dramatically in recent decades due to its cost-effectiveness, convenience, speed, and utility for a variety of contexts, including social, scientific, cultural, political, authentication, advertising applications. Spam is an sent large number individuals or organizations without the recipient's desire request. It increasingly becoming harmful part traffic can negatively affect usability systems. Such emails consume network bandwidth as well...

Abstract The growing use of the Internet with its vulnerabilities has necessitated adoption Intrusion Detection Systems (IDS) to assure security. IDSs are protective systems that detect outsider infiltrations, unauthorised accesses and malfunctions occurring in computer networks. Intrusions can be detected reported network administrator by using various pieces information such as port scanning irregular traffic detection. detection is a classification problem, identifying effective features...

Abstract Automated sentiment analysis is considered an area in natural language processing research that seeks to understand a text author's mood, thoughts, and feelings. New opportunities challenges have arisen this field due the popularity accessibility of variety resources ideas, such as online review websites, personal blogs, social media. Feature selection, which can be conducted using metaheuristic algorithms, one steps analysis. It crucial use high-performing algorithms for feature...

Clustering in wireless sensor networks is one of the crucial methods for increasing network lifetime. There are many algorithms clustering. LEACH algorithm important clusters based network. In this paper we proposed a new clustering method distribute several sensors with high-energy managing cluster heads and decrease their responsibilities These used as gateway between head base station. The simulation results shows, protocol probability failure nodes lifetime WSNs.

A bstract Different nature‐inspired meta‐heuristic algorithms have been proposed to solve optimization problems. One of these is called social spider (SSO) algorithm. Spiders' natural behaviors inspired them find the bait position by detecting vibrations in their web. Although SSO algorithm has good accuracy achieving optimal solutions, it suffers from a low convergence rate. In this paper, we attempted improve changing its motion and mating parameters. To provide practical example using new...

Clustering in wireless sensor networks is one of the crucial methods for increasing network lifetime. There are many algorithms clustering. One cluster based algorithm LEACH algorithm. In this paper we proposed a new clustering method done symmetrically and best node with respect to remained energy distance other nodes comparing each that selected as head. Although protocol didn't use GPS but could find geographical position so easily. performance via computer simulation was evaluated...

Limitation of energy consumption that impress lifetime sensor network directly, is one the major challenges in wireless networks.In this paper, a confident communication protocol presented include low for networks dispense monotonous cargo between sensors and increases lifetime.This cluster-Based originated from combination DBS clustering by using cellular learning automata.Based on proposed protocol, cluster head nodes are identified various phases based parameters: 1) amount node 2)...

Abstract One of the most important and costly stages in software development is maintenance. Understanding structure will make it easier to maintain more efficiently. Clustering modules thought be an effective reverse engineering technique for deriving structural models from source code. In module clustering, essential objectives are minimize connections between produced clusters, maximize internal within created clustering quality. Finding appropriate system model considered NP‐complete...

In recent years, wireless sensor networks are in great use applications like disaster management, combat field reconnaissance, border protection and safe care.Although, much research has been done on networks, but the quality of service (QoS) there not enough researches.Since these widely used many areas, different QoS parameters contrast with traditional such as network coverage, optimal number active nodes, lifetime energy consumption.We have proposed an automata-based scheduling method to...
