Abstract-In IEEE 802.11 standard, the use of multi-channel is one of the most important characteristic features contributing to the improvement of the overall network throughput. However, the channel utilization based on the use of multi-channel is relatively low because most medium access control (MAC) protocols were designed based primarily on the application of non-overlapping channels. This paper...
The paper presents a cross-layer energy-efficient and reliable routing (named CLE2aR2) protocol to construct an energy efficient and reliable route and resist the variation of wireless channels for wireless ad hoc networks. CLE2aR2not only considers how to construct a route from the source to the destination, but also takes some important lower-layer factors, such as power strength, data transfer...
The paper proposes an RCA MAC protocol to reduce RTS collisions. The protocol utilizes a narrow band, called the tone channel, to announce the RTS transmission in advance to preclude the RTS transmissions of two-hop neighbors. To reduce the channel and hardware overhead, an improvement to the RCA protocol is also devised, which only uses a single channel and one transceiver to reduce RTS collisions...
