Special Issue Information

Dear Colleagues,

A number of practical scenarios of wireless sensor networks mandate harvesting and processing of multimedia data, e.g., video data in networked surveillance systems. Proliferation of smart sensors and advances in wireless communications technologies are the main driving forces for realizing wireless sensor networks with media data processing, but there are still some remaining challenges, including energy-efficient in-network media processing and QoS for heterogeneous media traffic. Further, machine learning techniques have paved the way for complex sensing tasks and opened up new opportunities in media processing. Many researchers and professionals are accustomed to applying machine learning-based techniques to solve various issues in wireless multimedia sensor networks. This Special Issue aims to showcase recent developments in the field of wireless multimedia sensor networks ranging from theory to applications.

In wireless local area networks (WLANs), the effect of interference signals between neighboring nodes increases as the number of wireless nodes using limited radio frequency resources in a limited space increases, which can significantly degrade the reliability of data transmission. In high-density WLANs, there can be several neighboring access points (APs) that can receive uplink transmission from a station. In conventional medium access control (MAC) protocols, uplink data frames containing errors or transmitted from a non-associated station are discarded at APs. Alternatively, we propose a MAC protocol using redundant wireless links between neighboring APs and the non-associated stations. In the proposed MAC protocol, we consider a centralized WLAN with a control node that performs error corrections of erroneous uplink data frames via a majority voting algorithm-based link-layer diversity scheme using uplink data received from multiple APs to increase the reliability of data transmission. In addition, we propose an adaptive carrier sensing ranging mechanism to improve the uplink network throughput in the proposed centralized WLAN system. Further, we conduct simulation studies and software-defined radio-based experiments to evaluate the performance of the proposed MAC protocol in various WLAN scenarios. Full article
