ملخص المقالة :
شبکه قدرت فعلی اشکالات زیادی دارد. اخیراً یک شبکه جدید و هوشمند برای رفع کاستی‌های شبکه فعلی معرفی شده که از آن با عنوان شبکه هوشمند انرژی یاد می‌شود. شبکه هوشمندی که بخواهد شبکه قدرت را به‌طور کارامدی مدیریت کند، به یک زیرساخت مخابراتی برای برقراری ارتباط بین اجزای شبکه نیاز دارد. فناوری مخابراتی رادیو شناختگر به‌منظور بهره‌برداری کارامدتر از منابع طیفی رادیویی معرفی شده است. مسیریابی در این شبکه‌ها باید توسط پروتکلی انجام شود که در مقابله با مشکلات ایجادشده توسط رادیو شناختگر گذردهی را حداکثر کند و تأخیر بسته‌ها در آن حداقل و مناسب کاربرد شبکه هوشمند انرژی باشد. CORPL به عنوان پروتکلی که بخشی از این اهداف را محقق می‌سازد معرفی شده است. در این مقاله پروتکل CORPL تحت بار ترافیکی برست و پواسون بررسی می‌گردد و نشان داده می‌شود که با افزایش کاربران فعال در شبکه عملکرد CORPL افت پیدا خواهد کرد. سپس با استفاده از روابط ریاضی کران بالای میانگین تأخیر در پروتکل CORPL مدل شده و برای کاهش آن یک طرح چنددروازه‌ای ارائه می‌گردد.
