Optimization of Transmission Range for a Fault Tolerant Wireless Sensor Network

Applications of wireless sensor network face many censorious issues, fault tolerance being a prominent one. The problem of missing communication link(s), sensor node(s) and data is unavoidable in such networks. Fault tolerance is important for reliable delivery of data in WSN applications. This ensures the system's availability for use in case of any interruption or occurrence of fault, thus enhancing the availability and reliability. Current work introduces the fault-tolerance behavior of a dynamically generated system of wireless sensor network that comprises of super-nodes and sensor nodes having k - vertex disjoint paths. As the parameters involved in the process of determination of fault-tolerance of a network change, the capacity of the network to tolerate the fault changes accordingly. This paper proposes an algorithm that evaluates the fault tolerance of randomly generated networks based on k - vertex disjoint path connectivity and also evaluates the results.
