Wireless communication from a sender to a receiver is significantly affected by the interference generated by other devices. If devices in the vicinity of the receiver transmit at the same time and on the same frequency channel, their signals interfere at the receiver with the intended signal from the sender and thus impede proper reception.
A protocol for the selection of relay devices operating in the data link layer of wireless networks was proposed, specified, and evaluated. It is now being tested in a vehicular environment.
Different communication protocols for relay selection in wireless networks have been modeled using Markov chains in order to analyze and compare their performance.
