IEEE Workshop on Local and Metropolitan Area Networks (LANMAN)

作者： D. Lal T. Joshi D.P. Agrawal OBR Research Center of Distributed and Mobile Computing ECECS University of Cincinnati Cincinnati OH USA

In our paper, we investigate some MAC layer issues associated with the use of multiple-beam smart antennas at nodes in a distributed wireless ad-hoc network. We propose a transmitter-initiated on-demand MAC protocol that exploits the spatial parallelism in the transmission of packets at a node. We devise two MAC scheduling strategies in the one-hop neighborhood of a node, largest edge first (LEF) and largest degree node first (LDNF), that allow spatial parallelism to be exploited in the transmission as well as reception of packets. Our simulation results indicate that significant gain may be achieved through our scheduling strategies in a one-hop traffic bottleneck.

A novel priority based scheduling scheme for ad hoc networks

A novel priority based scheduling scheme for ad hoc networks

IEEE Conference on Vehicular Technology (VTC)

作者： Jun Yin Qing-An Zeng D.P. Agrawal OBR center for Distributed and mobile computing ECECS University of Cincinnati Cincinnati OH USA

Since ad hoc networks provide users convenient access to information anytime anywhere, they have many applications. However, scheduling packet based on assigned priority is challenging. This paper presents design and analysis of a priority request to send (RTS) packet scheduling (PRPS), a distributed MAC protocol which can ensure priority based packet scheduling for multiple traffic flows when different priority classes of traffic are present. For PRPS, nodes send their requests in a contention period and send data packets in a contention-free period and a state transition mechanism supports a change between contention and contention-free phases. An analytical model is introduced to determine the system performance when the traffic is in saturated region. The results of PRPS are compared with that of the IEEE 802.11 standard. Extensive simulations indicate that the system performances such as throughput and the average delay etc, are improved with respect to the IEEE 802.11 distributed coordination function (DCF).

作者： Xiaodong Wang Jun Yin D.P. Agrawal OBR center for Distributed and mobile computing ECECS University of Cincinnati Cincinnati OH USA

The paper introduces an analytical model to investigate the energy efficiency of the IEEE 802.11 distributed coordinated function (DCF). Many factors, such as the number of contending nodes, packet size, contention window, packet transmission collision probability and channel condition, that affect the energy efficiency of 802.11 DCF have been considered. We determine the packet transmission probability by a method simpler than the existing Markov chain model. The paper identifies the tradeoff in choosing packet size to optimize the energy efficiency of DCF in error-prone environments. The effects of contention window and packet size on the energy efficiency are obtained for both DCF basic mode and DCF with four-way handshaking. It is shown that under error-prone environments, optimal packet size can improve more on the energy efficiency than optimal contention window. Combining both optimal contention window and optimal packet size can achieve the maximum optimization. To validate our analytical results, we have done extensive simulations, and they seem to match very well with the presented analytical results.

Tins paper presents CMAC, a fully desynchronized MAC protocol that is designed to exploit the existing multi-channel support in sensor nodes. The hardware requirements of our protocol are minimal, requiring a single half-duplex transceiver and a low-power wake-up radio. CMAC takes into account the fundamental energy constraint in sensor nodes by placing them in a default sleep mode and waking them up only when necessary. As a contrast to other dual radio wake-up schemes, our protocol focuses on how communication and its preceding control message exchange mechanism can be undertaken in a multi-channel scenario without assuming a separate control channel. CMAC enables spatial channel re-use, nearly collision free communication, and addresses the deafness problem without incurring a tradeoff in fairness or latency. When compared with a recent MAC protocol SMAC, results show that CMAC obtains nearly 200% reduction in energy consumption, significantly improved throughput, and end-to-end delay values that are 50-150% better than SMAC for our simulated topologies

Historically, a large number of small and cheaper sensors are deployed to form a sensor network. This paper provides rationale behind using an Aggregate Logical Sensor Unit (ALSU) as a building block in a Wireless Sensory Information network (WSIN). In this architecture, a single ALSU is composed of many off-the-shelf sensor nodes in the manner similar to the Beowulf cluster concept. The highly capable, cost effective and flexible ALSUs built in this manner from several smaller physical sensor nodes, would enable high computation power and built-in reliability for sensor applications. The objective of this paper is to provide an alternative where energy and computation is not a limiting factor in order to achieve the operational objectives of WSIN applications. This paper highlights critical issues that need to be addressed in developing a framework where each ALSU could have the capability to perform required operations as dictated by an underlying application. © 2005 IEEE.

Impact of selfish nodes on route discovery in mobile ad hoc networks

IEEE Conference and Exhibition on Global Telecommunications (GLOBECOM)

作者： Qi Zhang D.P. Agrawal OBR Center for Distributed and Mobile Computing ECECS University of Cincinnati Cincinnati OH USA

It is against our intuition that being selfish sometimes can be beneficial to both oneself and others. In a mobile ad hoc network (MANET), we show potential use of this concept by categorizing mobile hosts into normal nodes and selfish nodes. Normal nodes forward packets for other nodes while selfish nodes do not. The advantage of using selfish nodes is that the total rebroadcast traffic during flooding based route discovery can be reduced. The disadvantage, in theory, is that we may miss the optimal route and suffer from a low delivery rate. In this paper, we propose a probabilistic approach to set up a proper number of selfish nodes. Using a combination of gossiping and dominating set, we can reduce the route discovery cost by minimizing the number of rebroadcasts, while achieving higher delivery rate due to the reduction of rebroadcast traffic, thereby reducing the number of collisions. We compare our approach with AODV in terms of several metrics, including average number of rebroadcasts, average number of packet collisions, end-to-end delay, and throughput. Simulation results show that our approach outperforms the AODV protocol in most cases.

Wireless Telecommunications Symposium, WTS

作者： H. Wang W. Li D.P. Agrawal OBR Center for Distributed and Mobile Computing ECECS University of Cincinnati Cincinnati OH USA

IEEE 802.16 wireless MAN is expected to revolutionize of the broadband wireless access technology. The grant/request mechanism in IEEE 802.16 MAC provides different quality of service (QoS) for different service flows. In the paper, we discuss the QoS issue in IEEE 802.16 wireless MANs and propose an admission control scheme for services defined in the 802.16 specifications. Our proposed scheme provides the highest priority for UGS flows and maximizes the bandwidth utilization by bandwidth borrowing and degradation. We also develop an analytical model to evaluate the system performance. Some numerical results are included to provide a better understanding of our scheme.

IEEE Conference on Wireless Communications and Networking

作者： Xiaodong Wang Jun Yin Qi Zhang D.P. Agrawal OBR Center for Distributed and Mobile Computing ECECS University of Cincinnati Cincinnati OH USA

Due to the high node density and stringent constraints on the energy consumption in wireless sensor networks, designing an energy efficient flooding scheme with high reachability is critical for the operation and the lifetime of sensor networks. Many existing flooding approaches address the needs of general ad hoc networks. In contrast, this paper presents a cross-layer approach tailored specifically to the needs of sensor networks. Without assuming location awareness, a novel MAC layer access-deferring scheme, based on the received signal power, is proposed to reduce the collision possibility and broadcast redundancy. Local neighborhood information is piggybacked onto the broadcast packet, and exploited to enhance the reachability. Simulation results show that compared with probabilistic flooding, this scheme has good performance in terms of reachability, average delay and energy efficiency. Moreover, we examine how the range estimation error and neighborhood information inaccuracy introduced by the fading environment affects the performance of our flooding scheme.

Dynamic probabilistic broadcasting in mobile ad hoc networks

Dynamic probabilistic broadcasting in mobile ad hoc networks

IEEE Conference on Vehicular Technology (VTC)

作者： Qi Zhang D.P. Agrawal OBR Center for Distributed and Mobile Computing ECECS University of Cincinnati Cincinnati OH USA

In mobile ad hoc networks (MANET), broadcasting is extensively used in route discovery, address resolution, and many other network services. The efficiency of broadcasting protocol can dramatically affect the performance of the entire network. Proper use of probabilistic method can reduce the number of rebroadcasting, therefore reduce the chance of contention and collision among neighboring nodes. A good probabilistic broadcast protocol can achieve high throughput and low energy consumption without suffering significant reachability degradation. In this paper, we propose a dynamic probabilistic approach and compare it with simple flooding and fixed probabilistic scheme. Our approach dynamically adjusts the rebroadcasting probability according to the node distribution and movement in the ad hoc network. The adaptation is based on locally available information without the assistance of location or distance measuring devices. Simulation results show our approach perform better than both simple flooding and fixed probabilistic schemes.
