A queue management algorithm for QoS provisioning in WMSN

Abstract

Wireless Multimedia Sensor Network (WMSN) is an advanced concept of general wireless sensor network with multimedia sensing function. The development of WMSN is getting realized in accordance with the increased demands to provide multimedia data transmission services based on wireless sensor networks. It requires a traffic control mechanism that can support Quality of Service(QoS) to handle different services efficiently. This paper classifies traffic in WMSN as periodic monitoring traffic, event traffic, multimedia traffic and query-based traffic. This paper proposes traffic control mechanism that guarantees differentiated QoS in regard to type and feature of WMSN traffic and conducts performance analysis for our mechanism. © 2010 Springer-Verlag Berlin Heidelberg.
