Throughput-Optimal Scheduling with Low Average Delay for Cellular Broadcast Systems
While a number of scheduling policies achieve the maximum throughput region, the average delay minimization problem for cellular broadcast systems still awaits its complete solution. To this end, we introduce a scheduling policy which decomposes the cross-layer delay optimization problem into two subproblems: allocation of physical resources and user priority management. The first subproblem is...
متن کاملDelay and Throughput Optimal Scheduling for OFDM Broadcast Channels
In this paper a scheduling policy is presented which minimizes the average delay of the users. The scheduling scheme is investigated both by analysis and simulations carried out in the context of Orthogonal Frequency Division Multiplexing (OFDM) broadcast channels (BC). First the delay optimality is obtained for a static scenario providing solutions for specific subproblems, then the analysis i...
متن کاملDelay Optimal Scheduling for Chunked Random Linear Network Coding Broadcast
We study the broadcast transmission of a single file to an arbitrary number of receivers using Random Linear Network Coding (RLNC) in a network with unreliable channels. Due to the increased computational complexity of the decoding process (especially for large files) we apply chunked RLNC (i.e. RLNC is applied within non-overlapping subsets of the file). In our work we show the optimality of t...
متن کاملDelay-Optimal Scheduling for Queueing Systems with Switching Overhead
We study the scheduling polices for asymptotically optimal delay in queueing systems with switching overhead. Such systems consist of a single server that serves multiple queues, and some capacity is lost whenever the server switches to serve a different set of queues. The capacity loss due to this switching overhead can be significant in many emerging applications, and needs to be explicitly a...
متن کاملPower Efficient Broadcast Scheduling with Delay Constraints
Scheduling is an important technique in achieving higher throughputs or lower powers in wireless networks [1]–[4]. We showed that in the single user scenario, transmission power can be significantly reduced by increasing packet delays in both fading channels and additive white Gaussian noise (AWGN) channels with bursty input [5], [6]. In AWGN channels, when the input traffic is bursty, reductio...
