—In a wireless sensor network, the network lifetime is an important issue when the size of the network is large. In order to make the network scalable, it is divided into a numbe...
—— The performance of multiuser MIMO downlink systems with block diagonalization (BD) relies on the channel state information (CSI) at the transmitter to a great extent. For ti...
—An interesting feature of the 3G cellular networks is their ability to support multiple data rates. Though the performance of TCP over wireless networks has been well studied, t...
Abstract— Spam has been a serious problem for email causing frustration and annoyances to customers. This problem is growing at a fast rate with no signs of abating. Another form...
— Many previously proposed routing metrics and algorithms for ad hoc networks work well in static networks, however, when nodes are moving and wireless links may fail from time t...
— In this paper we investigate the impact of mobility on downlink scheduling in multi-user multiple antenna systems. We formulate several different designs of the cross-layer sch...
— The IEEE 802.11e standard supports a Direct-Link Setup (DLS) mechanism optionally to improve the throughput. Using this mechanism, IEEE 802.11e stations in proximity can direct...
