Abstract:

Wirless Sensor Networks (WSNs) are wireless networks, which to transmit packets between sensor nodes does not require any infrastructure.each sensor node acting both as ahost and router. To quantitatively measure quality of service, several related aspects of the network service are often considered, such as error rates, bit rate, throughput, transmission delay, availability, jitter, etc. The main function ofQuality of Service (QoS) routing in WSNs is to establish routesbetween different sensor nodes that ability to maintain Quality of Service (QoS) requirements such as bandwidth, end-to-enddelay and to be able operate within the limited energy constraints. Ad Hoc On-Demand Distance Vector (AODV) andDynamic Source Routing (DSR) protocols are two of the most on-demand protocols used in WSNs. Reactive (or on-demand)routing protocols find a path between the source and thedestination only when the path is needed (i.e., if there are data to be exchanged between the source and the destination). Theseprotocols use shortest path as main metric to establish routing between source and destination. This paper presents an overviewof reactive routing protocols in QoS which use delay as a main scale.
