A Hierarchical Multi-hop Multimedia Routing Protocol for Wireless Multimedia Sensor Networks

A Hierarchical Multi-hop Multimedia Routing Protocol for Wireless Multimedia Sensor Networks

Wireless Multimedia Sensor Networks (WMSNs) play an important role in pervasive and ubiquitous systems. WMSNs promise a wide scope of potential applications in both civilian and military areas, which require visual and audio information such as environmental monitoring, smart parking, traffic control, and other applications for smart cities. The multimedia content in such applications has the p...

A Geographic Multipath Routing Protocol for Wireless Multimedia Sensor Networks

A multi-objective routing algorithm for Wireless Multimedia Sensor Networks

In this paper a new multi-objective approach for the routing problem in Wireless Multimedia Sensor Networks (WMSNs) is proposed. It takes into account Quality of Service (QoS) requirements such as delay and the Expected Transmission Count (ETX). Classical approximations optimize a single objective or QoS parameter, not taking into account the conflicting nature of these parameters which leads t...

A Multi-hop Uneven Hierarchical Routing Protocol for Wireless Sensor Networks Using a Controlled Mobile Sink

Use of mobile devices for data collection in wireless sensor networks (WSNs) has recently drawn much attention. Controlled sink mobility has been shown to be beneficial in energy conservation and lifetime prolongation. In this paper, we aim at studying the multi-hop uneven hierarchical routing protocol (MUHRP) using different mobile sink strategies. We first analyze the performance of multi-hop...

A Fuzzy Based Approach for Rate Control in Wireless Multimedia Sensor Networks

Wireless Multimedia Sensor Networks (WMSNs) undergo congestion when a link (or a node) becomes overpopulated in terms of incoming packets. In WMSNs this happens especially in upstream nodes where all incoming packets meet and directed to the sink node. Congestion in networks, if not handled properly, might lead to congestion collapse which deteriorates the quality of service (QoS). Therefore, i...
