Abstract—This paper investigates Orthogonal FrequencyDivision Multiple-Access (OFDMA) resource-allocation schemes for two-hop relays in a home Powerline Communication (PLC) netwo...
—Most of geographic routing approaches in wireless ad hoc and sensor networks do not take into consideration the medium access control (MAC) and physical layers when designing a ...
Wireless networks, and especially wireless sensor networks, have complexity and energy constraints, within which they must confront the challenging wireless fading environment. In ...
