Fault Tolerant WSN with One Hop Boundary Detection

Wireless sensor network (WSN) mainly consists of detecting devices which have limited power. When the energy gets exhausted, the data transmission in the network gets interrupted; this leads to consequences like risk for human lives, depletion of natural resources etc. In order to prevent such consequences, we propose an energy efficient fault tolerant One Hop Boundary Detection (OHBD) algorithm for WSN. The proposed algorithm is compared with an existing algorithm like BNFD and results show that OHBD achieves 40 % higher boundary stability with higher network lifetime compared to BNFD.
