Traffic-Differentiation-Based Modular QoS Localized Routing for Wireless Sensor Networks

Free registration required

Executive Summary

A new localized Quality of Service (QoS) routing protocol for Wireless Sensor Networks (WSN) is proposed in this paper. The proposed protocol targets WSN's applications having different types of data traffic. It is based on differentiating QoS requirements according to the data type, which enables to provide several and customized QoS metrics for each traffic category. With each packet, the protocol attempts to fulfill the required data-related QoS metric(s) while considering power efficiency. It is modular and uses geographical information, which eliminates the need of propagating routing information. For link quality estimation, the protocol employs distributed, memory and computation efficient mechanisms.
