k-best paths in fault tolerant bi-directional heterogeneous wireless Sensor networks

In this paper a procedure is proposed to construct a heterogeneous wireless Sensor network (WSN) that is both bi-directional and fault tolerant. Fault tolerance, is based on finding the k-best disjoint paths using trellis graph transformation. Recognizing limited energy in WSN's the proposed al...

Description
Summary:In this paper a procedure is proposed to construct a heterogeneous wireless Sensor network (WSN) that is both bi-directional and fault tolerant. Fault tolerance, is based on finding the k-best disjoint paths using trellis graph transformation. Recognizing limited energy in WSN's the proposed algorithm minimizes energy consumption. Simulation study reveals how metrics, such as average end to end delay, transmission overhead and throughput, compare for unidirectional and bidirectional graphs.
