—In this paper, we study the node clustering problem in UnderWater Sensor Networks (UWSNs). We formulate the problem into a cluster-centric cost-based optimization problem with a...
— We propose an open-loop two-dimensional linear pre-transformed (2DLPT) multiple-input multipleoutput (MIMO) orthogonal frequency division multiplexing (OFDM) system. The nT N Ã...
—We present two Maximum Likelihood (ML) based estimators for Non-Data-Aided (NDA) symbol timing recovery in MIMO systems. These estimators are based on the classical Unconditiona...
— Modern cities are becoming increasingly networked Network Operator and the Service Providers can introduce environments and a plethora of computing equipment interacts their ow...

— Generalized selection multiuser diversity (GSMuD) is a new scheduling scheme which provides a near-optimal low-complexity solution to parallel access multiuser scheduling. In t...
– In this paper, we propose an auction mechanism for routing in mobile ad hoc networks with selfish nodes. Our approach is to promote bidding for end-to-end routes, as opposed to...
—The loss of UDP/IP packets has a high impact on the quality of the low-rate video streaming, since one UDP/IP packet typically represents a considerable part of a picture, which...
—In this paper we study the propagation of malicious software in wireless ad hoc networks under a probabilistic framework. We design topology control algorithms for the developme...
