Explaining consumers' channel-switching behavior using the theory of planned behavior
The study was exploratory and examined channel-switching behavior using Theory of Planned Behavior in three retail channels (i.e. brick-and-mortar stores, catalogs, and the Internet). The theory assumes that individual attitudes and beliefs, along with subjective norms and control factors will lead …

Channel structure modification: Motivations and switching costs in manufacturer-distributor relationship
The creation, maintenance, and evolution of channel relationships between manufacturers and channel partners have long been important issues in the area of channel research. However, the issues of channel partnership dissolution have received very limited attention. The goals of this dissertation …

Cross-channel integration
… substantially. Retailers have developed multichannel strategies and, in particular, have integrated their offline channels with online channels. Such an integration of offline and online channels is associated with the concept of cross-channel integration. This cumulative dissertation aims to …

Performance of Wireless Networks Subject to Constraints and Failures
… domains, viz., throughput performance in multi-channel wireless networks where devices have heterogeneous and constrained channel switching capabilities, and feasibility of fault-tolerant broadcast in single channel wireless networks where devices can exhibit Byzantine or crash-stop failure.

On Reducing Delays in P2P Live Streaming Systems
… churn-induced delays, including delays from channel switching and streaming recovery, in current P2P streaming applications are typically in the scale of 10-60 seconds, which is far below the favorable user experience as in cable TV systems. These two issues in terms of playback latency and …

Alibi framework for identifying insider jamming attacks in half-duplex wireless local area networks
… - It cannot send on two different channels simultaneously due to a non-negligible channel switching time. - It cannot receive on two different channels simultaneously due to a non-negligible channel switching time. - It cannot send and receive on a channel simultaneously due to a …

Decision models for fast-fashion supply and stocking problems in internet fulfillment warehouses
… clear the inventory. The first topic proposes a switching solution for fast-fashion retailers who have preordered an initial or block inventory, and plan to use channel switching as opposed to multiple discounting steps. The FFS Multi-Channel Switching (MCS) problem then is to monitor real-time …

Load-Aware Traffic Control in Software-Defined Enterprise Wireless Local Area Networks
… implemented on a testbed. A load-aware automatic channel switching algorithm and a QoS-aware bandwidth control algorithm are proposed to achieve AP-based network traffic control. Experimental results from the testbed show that the designed system and algorithms significantly improve the …

Applications of machine to machine communication in remote healthcare systems
… takes practical thresholds including Co-Channel Interference (CCI) among CM2M devices, interference to the Primary Users (PUs), and Maximum Aggregation Span (MAS) into consideration. Simulation results clearly show that the developed algorithm outperforms State of The Art (SOTA) …

Traffic-aware channel allocation and routing in multichannel, multi-radio wireless networks
… the transmission spectrum into a narrow channel and a wide channel. The narrow channel is used for transmitting the short packets and the wide channel is used for transmitting the longer packets. We propose a protocol called WiSP (channel Width Selection based on Packet size) to estimate …

Green IPTV : a resource and energy efficient network for IPTV
… the major concerns of IPTV network deployment : channel change delay. This is the latency experienced by users when switching between TV channels. Synchronisation and buffering of video streams can cause channel change delays of several seconds. I perform an empirical analysis of a particular …

Learning-based Decision Making in Wireless Communications
… learning based framework for dynamic multichannel access. We consider both a single-user case and a scenario in which multiple users attempt to access channels simultaneously. In the single-user model, in order to evaluate the performance of the proposed channel access policy and the …

Some Modeling and Optimization Problems in Cognitive Radio Ad Hoc Networks
… spectrum access (DSA)) and interoperability (via channel switching). It is envisioned that CR will be employed as a general radio platform upon which numerous wireless applications can be implemented. For both theoretical and practical purposes, it is important for network researchers to model a …

Channel parameter tuning in a hybrid Wi-Fi-Dynamic Spectrum Access Wireless Mesh Network
This work addresses Channel Assignment in a multi-radio multi-channel (MRMC) Wireless Mesh Network (WMN) using both Wi-Fi and Dynamic Spectrum Access (DSA) spectrum bands and standards. This scenario poses new challenges because nodes are spread out geographically so may have differing allowed …
