@article{(Open Science Index):https://publications.waset.org/pdf/5224, title = {A Review of Coverage and Routing for Wireless Sensor Networks}, author = {Hamid Barati and Ali Movaghar and Ali Barati and Arash Azizi Mazreah}, country = {}, institution = {}, abstract = {The special constraints of sensor networks impose a number of technical challenges for employing them. In this review, we study the issues and existing protocols in three areas: coverage and routing. We present two types of coverage problems: to determine the minimum number of sensor nodes that need to perform active sensing in order to monitor a certain area; and to decide the quality of service that can be provided by a given sensor network. While most routing protocols in sensor networks are data-centric, there are other types of routing protocols as well, such as hierarchical, location-based, and QoS-aware. We describe and compare several protocols in each group. We present several multipath routing protocols and single-path with local repair routing protocols, which are proposed for recovering from sensor node crashes. We also discuss some transport layer schemes for reliable data transmission in lossy wireless channels.}, journal = {International Journal of Electronics and Communication Engineering}, volume = {2}, number = {1}, year = {2008}, pages = {67 - 73}, ee = {https://publications.waset.org/pdf/5224}, url = {https://publications.waset.org/vol/13}, bibsource = {https://publications.waset.org/}, issn = {eISSN: 1307-6892}, publisher = {World Academy of Science, Engineering and Technology}, index = {Open Science Index 13, 2008}, }
