دانلود A Survey on Fault Tolerant Routing Techniques in Wireless Sensor networks

Abstract

Wireless Sensor Networks are without a doubt one of  the  central  issues  in  current  research  topics  due  to  the  harsh  environmental  conditions  in  which  such  networks  can  be  deployed  and  their  unique  sensor  network  characteristics,  specifically   limited   power   supply,   sensing,   processing   and   communication  capabilities.    Presented  with  many  challenges  and  design  issues  that  affect  the  data  routing,  a  need  for  a  fault   tolerant   routing   protocol   becomes   essential.   In   this   paper,  we  summarize  and  highlight  the  key  ideas  of  existing  fault  tolerant  techniques  of  routing  protocols,  survey  existing  routing protocols proposed to support fault tolerance. Finally, we provide some future research directions in the area of fault tolerance in wireless sensor networks routing.
