We present Duo-MAC, an asynchronous cascading wake-up scheduled MAC protocol for heterogeneous traffic forwarding in low-power wireless networks. Duo-MAC deals with energy-delay minimization problem and copes with transmission latency encountered by Today's duty-cycled protocols when forwarding heterogeneous traffic types. It switches, according to the energy and delay requirements, between Low Duty...
The MAC protocol is important, especially for wireless LAN because of limited bandwidth. A great deal of research has been carried out and some of proposed schemes are effective. Specifically, considerable effort has been devoted to improving the IEEE 802.11 standard which is utilized widely. Previous theoretical analysis gave the upper bound of IEEE 802.11 DCF throughput which is far below the channel...
Bandwidth reservation in mobile wireless networks is a very challenging task due to the instability of radio channels, node mobility and lack of coordination between mobile nodes. Previously proposed reservation MAC protocols reserve a slot to each real-time source assuming that the source will use the reserved slot in each super-frame. Since different applications may have different bandwidth requirements,...
