في هذا البحث قمنا بدراسة و مقارنة أشهر مقاييس جودة الوصلات داخل شبكات الحساسات
اللاسلكية التي تعتمد على بروتكول التوجيه الشجري (CTP) المضّمن داخل نظام التشغيل
(TinyOS) و ذلك من أجل عدة نماذج لشبكة حساسات لاسلكية، و قمنا بإجراء محاكاة لهذه
المقاييس باستخدام محاكي الشبكات (TOSSIM) و ذلك من أجل تقييم أدائها.
In this PAPER, we perform a study and extensive comparative between
the well-known link quality estimators and CTP, a tree-based routing
protocol provided by TinyOS for different network topology and simulate
it using TOSSIM simulator to evaluate the performance of these
estimators.
