Here, the authors present a new concept of M Collectors instead of static collectors. M Collectors provides the mobility in the network. Main objective of mobile data-gathering scheme is to improve the scalability and solves intrinsic problems of large-scale homogeneous networks. This new concept under the mobility provides data gathering tour periodically from the static data sink, polls each sensor in single-hop communications, and finally transports the data to the data sink. They mainly focus on the problem of minimizing the length of each data-gathering tour and refer to this as the single-hop data-gathering problem.
