چکیده

Abstract


A wireless sensor network (WSN) consists of a group of energy-constrained sensor nodes with the ability of both sensing and communication, which can be deployed in a field of interest (FoI) for detecting or monitoring some special events, and then forwarding the aggregated data to the designated data center through sink nodes or gateways. In this case, whether the WSN can keep the FoI under strict surveillance and whether the WSN can gather and forward the desired information are two of the most fundamental problems in wireless sensor networks that need to be solved. Therefore, preserving network connectivity while maximizing coverage by using the limited number of energy constrained nodes is the most critical problem for the deployment of WSNs. In this survey article, we classify and summarize the state-of-the-art algorithms and techniques that address the connectivity-coverage issues in the wireless sensor networks.

Conclusion


Connectivity and coverage are two of the most important issues in WSNs, which can be considered as the sufficient conditions to utilize a WSN. Many research efforts have been proposed to cope with these problems. In this survey, firstly, we briefly introduced the basic knowledge on the notions of connectivity and coverage. Then, we summarized the research efforts proposed for addressing the connectivity problem, and then listed the critical conditions to keep system connectivity. Since the connectivity is affected by the node/link failures, we also did a survey for the research work related to the failure-resilient/fault-tolerant WSNs design problem. Further, we summarized the existing approaches addressed integrated connectivity and coverage problem. Based on the proposed conditions for keeping connectivity while preserving coverage, we described the research efforts proposed for coverage problem in the final.
