Routing protocol in MWSNs is spinal column for data communication. To the best of our knowledge, very little work has been done in this area. Recently, S. Kim et. Al proposes scheme named HRGC scheme [1] for data communication in MWSNs. However, HRGC scheme has many limitations.

      This paper gives experimental evaluation of HRGC scheme to highlight the limitations. The HRGC scheme is analyzed in terms of communication overhead, packet delivery ratio, packet loss ratio. The experimental results are achieved through different experiments carry out on MWSNs with varying size of network.  The paper highlights the critical issues of HRGC scheme. To the best of our knowledge, it is the first study of HRGC scheme for analyzing the scheme with different parameter. Our research work will be good guidance for new researcher in this field.
