Optimal reader location for collision-free communication in WRSN
2014 IEEE Global Communications Conference, 2014In wireless rechargeable sensor networks (WRSN), rechargeable sensor nodes harvest ambient RF energy from power sources such as the RFID readers. However, the simultaneous transmissions may cause severe communication collisions. Different from traditional approaches which mainly resolve such collisions at the MAC layer, in this work we optimize the ...
