Abstract

Wireless Multimedia Sensor Networks (WMSNs) are a special type of Wireless Sensor Network (WSN) where large amounts of multimedia data are transmitted over networks composed of low power devices. Hierarchical routing protocols typically used in WSNs for multi-path communication tend to overload nodes located within radio communication range of the data collection unit or data sink. The battery life of these nodes is therefore reduced considerably, requiring frequent battery replacement work to extend the operational life of the WSN system. In a wireless sensor network with mesh topology, any node may act as a forwarder node, thereby enabling multiple routing paths toward any other node or collection unit. In addition, mesh topologies have proven advantages, such as data transmission reliability, network robustness against node failures, and potential reduction in energy consumption. This work studies the feasibility of implementing WMSNs in mesh topologies and their limitations by means of exhaustive computer simulation experiments. To this end, a module developed for the Synchronous Energy Saving (SES) mode of the IEEE 802.15.5 mesh standard has been integrated with multimedia tools to thoroughly test video sequences encoded using H.264 in mesh networks.

Summary

Introduction

Wireless Sensor Networks (WSNs) [1] consist of a large number of low-cost and energy-constrained devices. Networks (WMSNs) [2] are regarded as a particular type of WSN where nodes are interfaced with sensors for visual and sound data acquisition, such as Complementary Metal Oxide Semiconductor (CMOS) cameras and microphones. This technology has drawn the attention of the WSN research community, encouraged by the challenge of providing support applications such as video surveillance, environmental monitoring, target tracking and traffic management, where multimedia services are required. Reliable transmission of multimedia data in WMSNs is challenging due to the inherent technology limitations, such as interference between devices or Sensors 2016, 16, 643; doi:10.3390/s16050643 www.mdpi.com/journal/sensors
