Optimal Utility-Energy tradeoff in Delay Constrained Random Access Networks
Optimal Utility-Energy tradeoff Delay Constrained Random Access Networks
2010/11/24
Rate, energy and delay are three main parameters of interest in ad-hoc networks. In this paper, we discuss the problem of maximizing network utility and minimizing energy consumption while satisfying...
Construction of Network Error Correction Codes in Packet Networks
Network Error Correction Codes Packet Networks
2010/11/11
Recently, network error correction coding (NEC) has been studied extensively. Several bounds in classical coding theory have been extended to network error correction coding, especially the Singleton...
Average Sum-Rate of Distributed Alamouti Space--Time Scheme in Two-Way Amplify-and-Forward Relay Networks
Average Sum-Rate Distributed Alamouti Space--Time Scheme Amplify-and-Forward Relay Networks
2010/11/11
In this paper, we propose a distributed Alamouti space-time code (DASTC) for two-way relay networks employing a single amplify-and-forward (AF) relay. We first derive closed-form expressions for the ...
Adaptive Algorithms for Coverage Control and Space Partitioning in Mobile Robotic Networks
Adaptive Algorithms Coverage Control and Space Partitioning
2010/11/9
We consider deployment problems where a mobile robotic network must optimize its configuration in a distributed way in order to minimize a steady-state cost function that depends on the spatial distr...
