- MRMC: A Multi-Rate Multi-Channel MAC Protocol for Multi-Radio Wireless LANs
- Dynamic transmission rate selection is widely used in IEEE 802.11b Wireless LANs WLANs to combat adverse wireless channel conditions. However, overall system throughput suffers when stations with different transmission rates share the same physical channel. This paper describes and evaluates a multi-rate multi-channel Medium Access Control MAC protocol to solve...

- On Scheduling and Real-Time Capacity of Hexagonal Wireless Sensor Networks
- Since wireless ad-hoc networks use shared communication medium, accesses to the medium must be coordinated to avoid packet collisions. Transmission scheduling algorithms allocate time slots to the nodes of a network such that if the nodes transmit only during the allocated time slots, no collision occurs. For real-time applications, by...

- A Proposal of Optical Wireless Communication With RF Subcarrier
- Optical wireless communication is safety for electric equipment, because it doesn't produce any electromagnetic waves. Therefore it is suitable for wireless communication on these places, and one needs to propose optical wireless access system for these places. And if one examines the characteristic of optical wireless communication, it is important...

- Cooperation, Competition and Cognition in Wireless Networks
- Nodes and/or clusters of a wireless network operating on the same frequency can operate using three different paradigms: Competition: traditionally, this is information theoretically casted in the framework of interference channels. Cooperation: silent transmitters/receivers can help active transmitters/receivers in the transmission/reception of their messages, but have to extract this message...
