چکیده

در این تحقیق، به ارزیابی روش‌های خوشه‌بندی انرژی کارآمد در شبکه‌های حسگر بی‌سیم می‌پردازیم. نتایج حاصل از این پژوهش حاکی از آن است که خوشه‌بندی توسط DBSCAN، امتیاز کارایی بالاتری نسبت به سایر روش‌های خوشه‌بندی به دست می‌آورد. به‌طوری‌که DBSCAN امتیاز کارایی ۹۹٪ را به دست آورد اما الگوریتم K-Means، امتیاز کارایی ۷۶٪ را به دست آورد. همچنین انرژی باقیمانده در شبکه پس از اتمام شبیه‌سازی در مسیریابی با پروتکل جدید حدود ۱۱٪ بیشتر از مسیریابی EEHC و حدود ۹٪ بیشتر از مسیریابی با پروتکل LCA است. اگر طول عمر شبکه را در زمان خاموش شدن اولین گره در شبکه در نظر بگیریم در پروتکل جدید اولین گره ۶ ثانیه دیرتر از پروتکل EEHC و ۱۲ ثانیه دیرتر از پروتکل LCA‌ خاموش می‌شود. این بدین معناست که به‌طور میانگین حدود ۱۰٪ طول عمر شبکه با پروتکل جدید افزایش‌یافته است. پروتکل I-LEACH راندمان انرژی و طول عمر را باکار بیشتر در همان ساختارها در مقایسه با پروتکل معمولی LEACH بهبود می‌بخشد.

چکیده [English]

In this research, we evaluate energy efficient clustering methods in wireless sensor networks. The results of this study indicate that clustering by DBSCAN has a higher efficiency score than other clustering methods. The DBSCAN scored 99%, but the K-Means algorithm scored 76%. Also, the energy remaining in the network after the simulation is completed in routing with the new protocol is about 11% more than routing with EEHC and about 9% more than routing with LCA protocol. If we consider the lifespan of the network when the first node in the network is turned off, in the new protocol, the first node shuts down 6 seconds later than the EEHC protocol and 12 seconds later than the LCA‌ protocol. This means that on average, about 10% of network life has been increased with the new protocol. The I-LEACH protocol improves energy efficiency and longevity by working more in the same structures than the conventional LEACH protocol.
