Network coding has attracted much interest recently since considerable research indicates that it can offer significant capacity gains. This paper applies network coding to mobile ad hoc networks, especially for large scale content distribution, where each network node is able to generate and transmit encoded blocks of incoming information. Furthermore, it introduces a novel scheduling approach named...
WLAN is becoming a promising system for future mobile ubiquitous network. However, the performance is largely restricted by MAC inefficiency, and AP remains as a bottleneck in infrastructure WLAN. A high efficient MAC, which decreases frame collision and balances the performance between AP and stations, is desirable. Therefore, we proposed an interactive pair scheduling (IAPS) scheme compatible with...
802.11 DCF defines a virtual carrier sense mechanism, via RTS/CTS handshaking, to reserve wireless channel. All the nodes overhearing either RTS or CTS set their network allocation vector (NAV) respectively, and defer the channel access for the expected time to finish the packet sequence transmission. The problems arise when RTS or CTS is not successfully received by the addressed node, which causes...
