Abstract

Kablosuz algılayıcı ağ ortamları, kablolu iletişim ile karşılaştırıldığında genellikle esneklik avantajı nedeniyle tercih edilmektedir. Bu makalede, kablosuz algılayıcı ağlar için gecikme duyarlı CSMA ortam erişim tekniğinin performans değerlendirmesi gerçekleştirilmiştir. Kablosuz algılayıcı düğümler, sınırlı enerjiye sahip olduklarından dolayı kayıpsız veri iletişimi için CSMA ortam erişim tekniğini kullanmaktadırlar. Enerji verimliliğini artırmak amacıyla, kablosuz algılayıcı düğümler boşta iken uyku durumuna geçerek bekleme yapmaktadırlar. Analitik modelin matematiksel olarak elde edilmesinden sonra, kablosuz algılayıcı ağ yapısının benzetim modeli Riverbed yazılımı kullanılarak tasarlanmıştır. Kablosuz algılayıcı ağın performansını analiz etmek için; gecikme, enerji ve iş çıkarma oranı parametreleri incelenmiştir. Performans değerlendirmesi sonuçları incelendiğinde, CSMA tekniği sayesinde ortalama gecikmenin önemli derecede düşürüldüğü görülmektedir. Ayrıca, enerji tüketimi makul düzeyde tutularak kablosuz algılayıcı düğümler sayesinde maksimum iş çıkarma oranı elde edilmektedir.

Performance Evaluation of Delay Sensitive CSMA Medium Access Technique for Wireless Sensor Networks

Abstract

Wireless sensor network environments are generally preferred because of their flexibility advantage when compared to wired communication. In this article, performance evaluation of delay sensitive CSMA medium access technique for wireless sensor networks was performed. Because wireless sensor nodes have limited energy, they utilize CSMA medium access technique for lossless data communication. In order to increase energy efficiency, the wireless sensor nodes get into the sleep state when they wait in idle state. After obtaining the analytical model mathematically, the simulation model of the wireless sensor network was designed using Riverbed software. To analyze the performance of the wireless sensor network; the parameters of delay, energy and throughput rate were investigated. When the performance evaluation results are analyzed, it is seen that the average delay is decreased significantly by CSMA technique. In addition, the maximum throughput rate is achieved with the help of wireless sensor nodes keeping the energy consumption at a reasonable level.
