چکیده مقاله :
محدوديت انرژي يکي از چالشهاي اساسی در شبکههاي حسگر بيسيم است که طول عمر شبکه را به صورت مستقيم تحت تأثير قرار ميدهد. يک راه حل بهبود کارايي عمومي شبکه و توزيع يکنواخت انرژي در آن، خوشهبندي گرههای شبکه است. انتخاب تعداد خوشهها براي رسيدن به يک گذردهي کارای شبکه کاري بس دشوار است زيرا با افزايش تعداد سرخوشهها، براي رسيدن بسته از مبدأ به مقصد، تعداد پرشهاي زيادي ميبايست صورت گيرد. افزايش تعداد پرشها باعث پردازش بیشتر اطلاعات و افزایش مصرف انرژي ميگردد. اين مقاله، يک روش خوشهبندي را با آگاهي از مكان و انرژي گرهها ارائه مينمايد که سعي در تشكيل خوشههايي با اندازه بهینه و انتخاب سرخوشه بر اساس سطح انرژي گرهها به منظور كاهش مصرف انرژي دارد. روش پيشنهادي محيط شبكه را به دواير متحدالمركزي تقسيم کرده و تعداد خوشه بهينه هر دور را به نحوي که مصرف انرژي شبکه بهبود يابد محاسبه میکند. در همين رأستا از الگوريتم شايعهپراکني به منظور تبادل انرژي بين گرهها استفاده مينمايد. كارايي بهتر اين روش از لحاظ افزايش طول عمر مفيد شبكه در مقايسه با روشهاي پيشين نظير ASH از طريق شبيهسازي بررسی شده است. روش پيشنهادي از نظر طول عمر شبكه در حدود 25% تا 40% روش ASH را بهبود بخشيده است.
The energy constraint is one of the key challenges in wireless sensor networks that directly affects the network lifetime. Clustering the sensor nodes is one of the possible approaches to improving the energy efficiency by uniformly distributing the energy consumption among the nodes. The number of appropriate clusters plays an important role in the network throughput. A Large number of clusters imply that packets pass more hops to reach the destination, which results in higher energy consumption. In this paper, we devise an energy and location aware clustering scheme that tries to optimize the number of required clusters. Moreover, the cluster heads are chosen according to their energy levels. The devised scheme partitions the network into concentric circles and calculates the appropriate number of clusters to provide an energy efficient network. A gossiping approach is used to provide information exchange mechanism. The performance of the devised approach is compared with ASH scheme. The simulation results show the network lifetime is improved from 25% to 40% in difference network scenarios.
