“…The main problem of the WRSN is how schedule to the MCD to charge sensor nodes in time. In order to solve multiple simultaneous charging requirements and limited capacity of the MCD, here we introduce three kinds of works: multiple MCDs [ 9 , 10 , 11 ], partial charging scheme [ 12 , 13 , 14 ], and clustering method [ 15 , 16 , 17 , 18 ].…”

“…As the battery capacity of different MCDs may be different, the charging scheme considering the battery capacity of the MCDs was proposed to plan charging tours and depot positions of MCDs in [ 10 ]. Authors in [ 11 ] proposed an online charging architecture which makes MCDs collaborate dynamically to minimize the energy hole rate. These works indicate that more sensors are charged in time and inevitably die in the WRSN with multiple MCDs.…”

“…To address these two problems, many works use multiple MCDs [ 9 , 10 , 11 ], propose partial charging scheme [ 12 , 13 , 14 ], or adopt clustering method [ 15 , 16 , 17 , 18 ]. In the WRSN using multiple MCDs, MCDs can charge many lifetime-critical sensor nodes simultaneously, which can effectively reduce expired sensor nodes.…”

Mobile charging devices (MCDs) have been regarded as a promising way to solve the energy shortage of wireless sensor networks. Due to ignoring some important factors, such as redundant sensor nodes, there is still room to improve network lifetimes. We propose a charging strategy for wireless sensor networks with one energy-limited MCD. To give the best support for sensor nodes which need charging the most, an algorithm is proposed to find the minimum sensor nodes which keep the coverage and connectivity of the network and have the least energy requirements. Then, the goal of maximizing network lifetime is changed into how to utilize the limited energy of the MCD to guarantee the minimum sensor nodes work as long as possible. If the MCD has enough energy for all sensor nodes, the charging algorithm is designed to minimize the outage time of the network and maximize charging efficiency. Otherwise, if the energy capacity is larger than the least energy requirement, the charging target minimizes the outage time of the minimum sensor node; otherwise the charging problem becomes maximizing the lifetime of minimum sensor nodes, which has lower complexity. The results of simulation experiments confirm that our scheme prolongs network lifetime and improves charging efficiency.

“…In the above article [1], we did not check the article carefully enough, which resulted in writing errors in some parts of the paper. In Table 1 of the original article, we incorrectly wrote the default charging efficiency of MC as 300 mJ/s, but the correct charging efficiency is 3000 mJ/s.…”
