Detection and patching of coverage holes in Wireless Sensor Networks (WSNs) are
important measures of Quality of Service (QoS) for security and other applications that …

Coverage holes may exist in wireless sensor networks (WSNs) due to presence of obstacles
or invalid sensor nodes in the sensing field. Normally, the holes make the data routing …

Wireless Sensor Networks (WSN) consists of distributed low-cost sensing nodes with
autonomous network. Several anomalies can occur in wireless sensor networks that may …

Wireless sensor network coverage completeness is an important Quality of Service
measure. It is frequently assumed that events occurring in the sensor field will always be …

Environmental factors such as unavoidable physical constraints, intentional destruction of
the sensors or asymmetric load distribution will lead to formation of holes in the wireless …

In this paper, we propose a simple and accurate coverage hole detection algorithm without
location information for wireless sensor networks. The coverage hole detection algorithm …

A connectivity based k-coverage hole detection algorithm is proposed in this paper. We
adopt Rips complex in homology theory to model a wireless sensor network (WSN). We …
