Routing in intermittent networks using storage domains
In this paper, we present a routing algorithm for a class of networks where a contemporaneous end-to-end path may not exist at the time of data transfer due to intermittent links. Several examples of such networks exist in the context of sensor networks,...
SCLDGM coded modulation for MIMO systems with spatial multiplexing and space-time block codes
We analyze Multiple-Input Multiple-Output (MIMO) coded modulation systems where either Bit-Interleaved Coded Modulation (BICM) with spatial multiplexing or concatenation of channel coding and Space-Time Block Codes (STBCs) is used at transmission, ...
Distributed spectrum assignment for cognitive networks with heterogeneous spectrum opportunities
This paper presents a distributed and localized interference-aware channel assignment framework for multi-radio wireless mesh networks in a cognitive network environment. The availability of multiple interfaces and channels in wireless devices is ...
Opportunistic delay-margin-based resource allocation for next-generation wireless networks
This paper studies and develops efficient traffic management techniques for downlink transmission at the base station (BS) of multi-service IP-based networks by combining quality-of-service (QoS) provision and opportunistic wireless resource allocation. ...
Reducing computational complexity using transmitter correlation value-assisted schedulers in multiuser MIMO uplink
In this paper, a threshold bounded antenna selection scheduler (TBS) and a computational complexity bounded antenna selection scheduler (CCBS) are proposed to reduce computational complexity in multiple input multiple output (MIMO) uplink. In contrast ...
A refined MAC protocol with multipacket reception for wireless networks
Medium access control (MAC) protocols making use of multipacket reception (MPR) capability achieve better throughput than conventional MAC protocols. When a wireless network operates with MPR capable nodes and non-MPR nodes, the MAC protocols must not ...
An efficient anycast scheme for discovering k services in cluster-based mobile ad hoc networks
Anycast is a one-to-any bidirectional transmission scheme that can be used to provide various service-oriented applications. However, traditional anycast cannot support some distributed applications that need to locate multiple servers such as network ...
Power control for delay constrained multi-channel communications using outdated CSI
In this paper, we study the power allocation scheme for a single user, multi-channel system, e.g., orthogonal frequency-division multiplexing (OFDM) systems, under time-variant wireless fading channels. We assume the receiver feeds back perfectly ...
Performance modeling of MPEG-4 video streaming over IEEE 802.11 using distribution coordination function
Delivering video streaming over wireless Internet is becoming increasingly popular. However, most of the research studies focused on the modeling analysis of system performance such as saturation throughput and channel utilization. Perceived quality of ...
