In a VRAM-SWWSN, assume the normal transmission range of the radio interface is estimated as 100 meters when using a modulation rate of 64QAM. For creating LLs, rate adaptation is employed in a dynamic manner to two lower modulation rates by adapting to the following two levels: (a) 32 QAM and (b) 8 QAM. Assume the path loss exponent is 2 and the trans- mission power is fixed. Estimate the transmission range of the LLs when operating at the two lower rates. Suggest a method to utilize the two LL ranges in a way to achieve energy efficiency in the SWWSN.
