Heterojen kablosuz algılayıcı ağ temelli sınır izleme sistemlerinde gizli veri kümeleme

Heterojen Kablosuz Algılayıcı Ağ (HKAA) temelli sınır izleme sistemleri sismik, video, ısı, ses gibi çeşitli algılayıcı türlerinin bir arada çalışarak sınır güvenliğini sağladıkları sistemlerdir. Bu sistemlerde elde edilen değişik türdeki veriler merkezi bir baz istasyonunda ya da veri toplayıcılarda analiz edilerek sınır güvenliği için tehlike oluşturan durumlar ortaya çıkarılır. Ancak toplanan verinin çok çeşitli olması, güvenlik derecesi yüksek kablosuz algılayıcı ağlar için gerekli olan veri kümeleme işleminin gizli bir şekilde yapılmasını zorlaştırır. Bu çalışmada HKAA temelli sınır izleme sistemlerinde şifrelenmiş değişik veri türlerinin gizli olarak kümelenmesine olanak sağlayan yeni bir veri kümeleme protokolü sunulmuştur. Önerilen protokolün özgün yönü toplanan verilerin kümelenmesi esnasında değişik veri tiplerinin tek bir paket olarak kümelenebilmesi ve baz istasyonunun kümelenmiş veriyi çözdüğünde verileri türlerine göre ayrı ayrı elde edebilmesidir.

Concealed data aggregation in heterogeneous wireless sensor network based border surveillance systems

Heterogeneous wireless sensor network (HWSN) based border surveillance systems are composed of several types of sensors such as video, temperature, seismic, and sound sensors. The data collected in these networks are analyzed by data aggregators or a central base station to determine illegal activities inside the border region. Due to high security requirements, concealed data aggregation is vital for mission critical HWSNs. However, since multiple sensor types that generate different data types, performing concealed data aggregation in these networks is not a trivial task. In this paper, a concealed data aggregation protocol that allows aggregation of multiple data types in border surveillance systems. The novel idea behind the paper is that the proposed concealed data aggregation protocol is able to aggregate different sensor data types into a single data packet. Moreover, the base station is able to obtain each different data type separately when it decrypts the aggregated data.
