Abstract    Topology construction and topology maintenance are significant sub-problems of topology control. Spanning tree based algorithms for topology control are basically transmission range based type construction algorithms. The construction of an effective backbone, however, is indirectly related to the placement of nodes. Also, the dependence of network reliability on the communication path undertaken by the message, subject to the place of event, remains unattended. To address this problem, we employ communication backbones (Prim’s algorithm and breadth first search (BFS)) and compute reliability based on the availability of paths for consistent message delivery from the place of event to the sink location in event driven wireless sensor networks. Our article analyses the communication reliability of a wireless sensor network in context to a topology governed by random and deterministic deployment methods. To comprehend the effect of topology on the communication reliability of a wireless network; “the within communication radii” constraint is satisfied. ANOVA is performed to validate the effect of node placement schemes on the reliability subject to varying radio ranges. It is observed that a ‘quasi’ random placement of nodes increases the communication reliability of the existing algorithms employed for analysis.

چکیده    ساخت و تعمیر و نگهداری توپولوژی زیر مشکلات قابل توجه کنترل توپولوژی هستند. الگوریتم­های چرخشی مبتنی بر درخت برای کنترل توپولوژی اصولاً بر اساس الگوریتم های ساخت و ساز گستره­ی انتقال هستند. البته، ساخت ستون مرکزی موثر به طور غیر مستقیم به استقرار گره­ها مرتبط است. همچنین، به وابستگی قابلیت اطمینان شبکه به مسیر مخابره­ی پیام با توجه به محل رویداد توجه نمی­شود. برای حل این مشکل، ما از ستون مرکزی ارتباطات (الگوریتم پریم و وسعت جستجو برای اولین بار (BFS)) استفاده کرده و قابلیت اطمینان را بر اساس در دسترس بودن مسیر برای تحویل پیام سازگار از محل رویداد به محل در شبکه­های حسگر بی سیم محاسبه می­کنیم. در این مقاله، ما قابلیت اطمینان ارتباطات را از شبکه­های حسگر بی سیم در زمینه به یک توپولوژی اداره شده با روش های استقرار تصادفی و قطعی محاسبه می­کنیم. برای درک اثر توپولوژی بر روی قابلیت اطمینان ارتباطات از یک شبکه بی سیم؛ "در داخل شعاع­های ارتباطات" محدودیت ارضاء می­کنیم. است برای اعتبارسنجی اثر روش_های استقرار گره­ها بر قابلیت اطمینان برای متغیرها در محدوده­ی رادیویی از تحلیل ANOVA استفاده می­کنیم. مشاهده شده است که استقرار شبه تصادفی گره­ها قابلیت اطمینان الگوریتم های موجود برای کار تحلیل ارتباطات را افزایش می­دهد.
