SADTCA Fazat e SADTCA Detektimi i antinyjeve Krijimi i grupimeve Shperndarja e celesave Rifreskimi i celesave Cdo nyje permban:  Celesi i Parashperndare, Celesi i Grupimit, Celesi Gateway Mesazh Identifikimi Stack i Celesave
Faza I: Detektimi i antinyjeve Cdo sensor ne momentin fillestar i transmeton te gjithe fqinjeve nje mesazh  Hello  qe te  identifikoje fqinjet e tij  ,  enkripton kete informacion (tekst i thjeshte) dhe me pas e transmeton; kur sensori fqinj merr mesazhin  Hello , ai e dekripton ate. Nqs dekriptimi eshte i sukseshem nyja konsiderohet normale perndryshe kemi te bejme me antinyje
Faza  II:  Krijimi i Grupimeve
 
Zgjedhja  Gateway
 
Ne kete faze,  Celesi I Grupimit  dhe  Celesi   Gateway , enkriptohen me Celesin e parashperndare shperndahen lokalisht.  Celesi I Grupimit  eshte nje celes I cili shperndahet nga nyja kryesore e grupimit ne te gjithe anetaret e grupimit , ky celes perdoret per sigurimin e mesazheve qe transmetohen lokalisht . Ne menyre qe te krijojme nje kanal te sigurt komunikimi ndernjet grupimeve ,perdoren Celesat Gateways ndermjet grupimeve fqinje Faza III: Shperndarja e Celesave
Faza IV: Rifreskimi i celesave
Metoda 1: Karantina per Grupimet Metoda 2: Karantina per Nyjet Metoda 3: Zonat e Infektuara Percaktimi i zonave ne karantine
Karantina per Grupimet & Karantina per Nyjet
Zonat e Infektuara
Rasti I:  Karantina  per Grupimet  Rasti  II:  Karantina  per Nyjet
Karantina per Zonat e Infektuara O =1/3   O=1/5
Conclusions We describe a secure protocol for topology management in wireless sensor networks. By adaptively forming quarantine regions, the proposed secure protocol is demonstrated to reach a network security agreement and can effectively protect the network from energy-exhaustion attacks.  Therefore, in a hierarchical network topology, the SADTCA scheme can adapt cluster control and neighborhood control in order to achieve dynamic topology management of the spam attacks.
