Using network coding in wireless networks can increase throughput and reduce energy consumption. Recently there are many works focusing on how to utilize network coding to increase throughput, however there are few works considering the quality of service such as delay which is important to time critical applications. This paper focuses on network coding based broadcast scheduling problem in time...
This paper studies the problem of relay-assisted user scheduling for downlink wireless transmission. The base station or access point employs hybrid automatic repeat request (HARQ) with the assistance of a set of fixed relays to serve a set of mobile users. By minimizing a cost function of the queue lengths at the base station and the number of retransmissions of the head-of-line packet for each user,...
It is a big challenge to design an effective scheduling algorithm for multimedia transmissions over a wireless channel that employs adaptive modulation and coding (AMC). On one hand, the scheduling algorithm needs to schedule user transmissions by taking advantages of the channel diversity so that the overall system performance can be improved. On the other hand, the algorithm also needs to maintain...
