We consider a wireless sensor network in which sensors are grouped into clusters, each with its own cluster head (CH). Each CH collects data from sensors in its cluster and relays...
Abstract--Discrete multitone modulation (DMT) systems exploit the capabilities of orthogonal subcarriers to cope efficiently with narrowband interference, high frequency attenuatio...
Abstract--This paper addresses practical implementation issues of resource allocation in OFDMA networks: inaccuracy of channel state information (CSI) available to the resource all...
Moving toward 4G, wireless ad hoc networks receive growing interest due to users’ provisioning of mobility, usability of services, and seamless communications. In ad hoc network...
