The reliable transmission of information is an inherently difficult and unpredictable task for LEACH-based networks. This is due to their adoption of centralized data exchange points which are expected to deliver data transmission reliability without being compromised by increasingly high rates of energy consumption. Given that this is a goal made more difficult by the constraints intrinsic to WSNs,...
Sensors in a Wireless Sensor Network (WSN) are prone to failure, due to energy depletion, hardware failures, etc. Fault tolerance is one of the critical issues in WSNs. The existing fault tolerant mechanisms either consume significant extra energy to detect and recover from the failures or need to use additional hardware and software resource. In this paper, we propose a novel energy-aware fault tolerance...
