Improved Network Lifetime and Hole Detection in Wireless Sensor Networks using Robot Repair Algorithm with Topology Control Fault Tolerance
Revista Técnica de la Facultad de Ingeniería Universidad del Zulia
The simple mode of the sensor nodes provides sensing which can be tampered with resulting in sensory nodes' erroneous observations. Tolerance of the system is highly improved using Wireless Sensor Network (WSN) which exhibit Fault-Tolerant behavior. The main advantage of the Topology Control Algorithm is that each node in multi-hop network can be adjusted to control the power at which transmission is made and set of neighbors with which it communicates can be chosen directly, preserving global
... preserving global goals such as connectivity or coverage. A theoretic approach mapping the problem of prolonging the network lifetime into an ordinal potential has been utilized in the Cooperative Topology Control with Adaptation (CTCA) proving the existence of Nash equilibrium for the healing methods. The complication of the CTCA algorithm can be overcome by the proposed Robot Repair Algorithm with Topology Control for identifying and isolating the multiple targets in the fault-tolerant way. The presented simulation results show the extended lifetime of a network by 50% more than the other algorithm utilization. On the functionality of the communication ranges of nodes and node density, the performance of the proposed algorithm is superior to that of any other approach. The comparison of different methods is presented with statistical data.
