Abstract: Sensing coverage with respect to WSN (Wireless Sensor Network) research has gained immense consideration. Implementation of WSNs in the domain of IoT (Internet of Things) ensures consideration of IoT features when thinking of sensing coverage. Both IoT and WSN are with respect to coverage hole metrics that includes network re-establishment, link establishing, throughput etc. Implementing sensor nodes may result in the issue of coverage holes if there is improper deployment of nodes. A coverage hole can exist in any region that is being monitored at any instance due to various purposes. As a result detecting coverage hole stand as a prime concern for gaining absolute coverage. Detecting coverage hole pose a big question for gaining high coverage in the Wireless Sensor Networks. The problem of coverage and connectivity particularly in coverage deployment strategy is analyzed for the weaker nodes and in case network design fails. The proposed algorithm referred to as ‘Store and Forward technique’ aids in identifying the coverage holes and network re-establishing in WSNs and IoT. Hence with the help of Store and Forward technique, network re-establishing and network stability can be performed in case of a coverage hole issue. The proposed technique is mostly employed in networks having irregular connectivity, specifically within environments where mobility is high. It’s also beneficial in conditions with long transmission and variable delays, maximum error rates, or cases where there is no direct, end-to-end link. The experiment output represents that the proposed healing method magnifies coverage rate with only a few additional sensors in contrast to the related methods.
