Prasenjit Chanak, Indrajit Banerjee, Hafizur Rahaman · 2013
This paper reports a distributed multipath fault tolerance routing scheme for wireless sensor network (DFTR). The multipath fault tolerance routing provides better resilience to various faults in wireless sensor network (WSN). However, the multipath fault tolerance routing has suffered by two problems regarding the routing strategy design. The first problem is that the traffic overhead becomes very high if the data are transmitted individually by the large number of duplicate routing paths between the source and base station. The second one is that the high traffic creates energy hole in the network which decrease the network life span rapidly. In this paper, a distributed multipath fault tolerant routing scheme has developed to tackle these problems in WSN. Effective size cluster formation is employed to prevent traffic over head and energy hole. Level based multipath tree mechanism is developed to tolerate nodes and transmission fault. The experimental results verify that the effectiveness and feasibility of the proposed work.
