We introduce an optimized Markov chain Monte Carlo (MCMC) technique for solving integer least-squares (ILS) problems, which include maximum likelihood (ML) detection in multiple-input multiple-output (MIMO) systems. Two factors contribute to its speed of finding the optimal solution: the probability of encountering the optimal solution when the Markov chain has converged to the stationary distribution,...
Devices in wireless networks, especially in ad hoc networks, are typically battery-powered. The need for energy efficiency in Mobile Ad Hoc Networks (MANETs) requires power enhancement features. Our work provides energy oriented power controlled mechanism to efficiently utilize the energy reserves and increase the network lifetime. The central idea is to select a Lead Node that will centrally manage...
