Target Coverage and Network Connectivity Challenges in Wireless Sensor Networks

Blog Article

Target Coverage and Network Connectivity in Wireless Sensor Networks (WSNs) plays a momentous role in the field ofmonitoring environment, habitant observing, disaster recovery, surveillance, etc.Coverage and Network Connectivitycollectively can be considered as a proportion of Quality of Service (QoS) in a sensor network.It implies the coverage ofeach point in the click here detecting field while in the meantime fulfilling the measure that each node is surrounded by theequivalent neighbourhood of at least one other node.

Many primary issues influence the outline and performance of WSN.A Comprehensive survey is made based on the scheduling algorithm and set cover approach, in which we analyze variousapproaches and their algorithm complexity.Firstly, the scheduling algorithm intermittently provides the required dataservice with guaranteed efficiency.

This methodology can efficiently reduce the entire number of active nodes in thenetwork, resulting in maximizing the network lifetime.Secondly, the set cover read more approach plays a major role in solvingtarget coverage problem which group sensors into each cover set thereby, target coverage was achieved.Typical issues andopen research challenges are addressed by classifying the approaches available in literature into three broad categoriesnamely, adaptable coverage radius, coverage deployment strategy, and sleep scheduling.

This survey aims to provide abetter perceptive of the existing open challenges and possible futuristic approaches for target coverage and networkconnectivity in wireless sensor networks.
