ملخص المقالة :
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.
