چکیده مقاله :
شبکه‌های حسگر بی‌سیم نسل جدیدی از شبکه‌ها هستند که از حسگرها برای دریافت اطلاعات پیرامون محیط خود استفاده می‌کنند و ارتباط این حسگرها به طور بی‌سیم است. یکی از مسایلی که در شبکه‌های حسگر بی‌سیم از اهمیت زیادی برخودار می‌باشد بحث کاهش مصرف انرژی و افزایش طول عمر شبکه است. کنترل توپولوژی یکی از روش‌های کاهش مصرف انرژی و افزایش طول عمر شبکه بوده و تاكنون روش‌هاي مختلف كنترل توپولوژي به منظور کاهش مصرف انرژی و افزایش طول عمر شبکه ارائه شده که از جمله آنها خوشه‌بندی است و یکی از روش‌های معروف خوشه‌بندی LEACH می‌باشد. در این مقاله ما سعی داریم یک روش خوشه‌بندی جدیدی ارائه دهیم که نسبت به LEACH و سایر روش‌های بهبودیافته بعد از LEACH برتری داشته باشد. ما در این روش خوشه‌بندی از منطق فازی دوسطحی استفاده می‌کنیم که باعث کاهش مصرف انرژی و افزایش عمر شبکه در مقایسه با روش‌های دیگر می‌شود و برای اثبات برتری روشمان در مقایسه با روش‌های دیگر، مقایسه‌ای با استفاده از نرم‌افزار MATLAB ارائه داده‌ایم.
Wireless sensor networks are a new generation of networks that from sensors uses to get information about itself environment and communication this sensors is as wireless. One of the issues that is very important in wireless sensor networks is Discussion reducing energy consumption and increasing network lifetime. Topology control is one of the methods to reduce energy consumption and increase the lifetime of the network. Since different methods of topology control, to reduce energy consumption and enhance the network lifetime is proposed that including them is the clustering and one of the most famous clustering methods is LEACH. In this paper, we try to present a new clustering method that is superior compared to leach and other improved methods after the LEACH. we use in our clustering method from two-level fuzzy logic that be causing reduce energy consumption and increase the network lifetime compared to other methods and to prove the superiority of our method compared with other methods, we present a comparison using MATLAB software.
