A delivery time-aware hole healing scheme for Wireless Sensor Networks

A Wireless Sensor Network must maintain a favorable sensing coverage and topology connectivity. In this work, hole heal priority is a method for increasing the coverage ratio, network lifetime, and shorter data transmit time. The algorithm, executed on the center of data receiver, is an analysis of two attributes of hole-block, one being the distance and another being the hole-block size. When a hole-block was selected, an optimum healing path can be decided. Experiments indicate the superiority of the proposed algorithm, especially the throughput and the delay time of the data conveyance.
