پروتکل چند سرعته و چند مسیره برای ضمانت کیفیت سرویس و قابل اطمینان بودن شبکه های حسگر بی سیم
چکیده: در این مقاله مجموعه ای تحت عنوان مکانیسم پروتکل شناسایی و ضمانت شبکه های حسگرهای بی سیم ارائه شده است. این کیفیت سرویس دهی در 2 حوزه « قابل اطمینان بودن» و « مناسب بودن» بررسی می شود. سطوح چند گانه کیفیت سرویس در حوزه « مناسب بودن » از طریق ضمانت عملکردهای چندگانه سرعت ایجاد می شوند. در حوزه « قابل اطمینان بودن» آنچه که لازم است تا این اطمینان حاصل شوداز طریق سیستم های احتمالی حمل و ارسال چند گانه بدست می آید. این عملکرد « کیفیت سرویس » از طریق مسیری متمرکز، بدون هیچگونه اطلاعاتی از سوی شبکه جهانی و تنها به روش به کارگیری یک سیستم جغرافیایی محلی ( متمرکز) با عنوان « تعادل پویا» حاصل می شود. بدین ترتیبٰ پروتکل چند سرعته و چند مسیره، شرایط پیوسته را به صورتی متمرکز ضمانت می کند. ( این شرایط برای اجرا در مقیاس های وسیع تر در شبکه حسگر های بی سیم لازم هستند). نتایجی که از یک شبیه سازی در این زمینه بدست آمد، نشان می دهد که ، این « کیفیت سرویس » هم از لحاظ قابل اطمینان بودن و هم از لحاظ مناسب بودن می تواند متفاوت باشد. از طرفی می تواند ظرفیت موثر یک حسگر شبکه ای را تا حدود 50 درصد افزایش دهد.
