The following Java APIs are used for fast Code 39 decoding from image file source. The first group allows you to choose Code 39 as target barcode symbol and direct our Java barcode decoder control to detect and read this barcode type only.

intrusion detection application running on a WSN may require the event detection decision to be made within a given delay bound [2] Other applications may require that the network deliver data packets to the sink with a given probability Similarly, the overall energy consumption of all communication events may be subject to energy consumption constraint Applications running on video sensor networks [3 5], which form a new and emerging class of WSNs, inherently require service guarantees from the communication network due to real-time nature of its multimedia source content These requirements are classi ed as quality of service (QoS) in other wired and wireless networks, which we also adopt for WSN environments We classify a communication protocol as QoS-based protocol if it can guarantee one or more performance metrics to upper layers or the application.

Under this classi cation, solutions that simply minimize/maximize a performance metric (delay, energy consumption, packet loss probability, network lifetime, etc) without performance guarantees are considered as non-QoS-based solutions We should note that most of the existing proposals for WSNs fall into non-QoS-based category In this chapter, we rst contrast QoS provisioning in WSNs and other network types and introduce a QoS provisioning framework for WSNs Then we outline and discuss proposed QoS-based communication protocols for WSNs We also outline methods that support QoS-based in-network processing along with communication for WSNs QoS-based capacity estimation methods are also discussed within the proposed framework We then conclude the chapter with future research directions 132 QoS IN WIRELESS SENSOR NETWORKS 1321 General Principles QoS has been the target of many communication protocols for numerous network types.

They prove that a message is guaranteed to be delivered, even if its delivery time is averaged over many timeslots This result sets a theoretical bound, since it assumes a complete mixing of the trajectories so that every node can get close to another one In the Infostation model [44], users can connect to the network in the vicinity of Infostations which are geographically distributed throughout the area of network coverage Infostations provide strong radio signal quality to small disjoint geographical areas and, as a result, offer very high rates to users in these areas However, due to the lack of continuous coverage, this high data rate comes at the expense of.

In its broadest form, quality of service refers to the contract between the service provider (ie, the network) and customers (ie, applications) [6] In wired networks, one of the main motivations for QoS solutions is the real-time multimedia applications that need bandwidth, delay, and jitter guarantees ATM networks [7] were proposed to support such requirements from ground up Although ATM networks are not as widely in use as originally imagined, QoS support mechanisms proposed for ATM networks still inspire new solutions In IP networks, QoS support of individual ows have been proposed to be handled through IntServ [8] mechanism, which has not gained widespread acceptance due to its scalability problems1 In cellular networks, the motivation for QoS support is also inherent to the primary application of such networks: Voice (and recently) video calls are subject to stringent constraints to be commercially viable.

frames) to retrieve its buffered packets Broadcast and multicast frames are handled using a delivery TIM (DTIM), and they are sent immediately after the beacons that contain the DTIM In IEEE 80211e, an automatic power-save delivery (APSD) scheme is de ned that allows the transmission of downlink frames synchronously based on periodic service intervals de ned by the hybrid coordinator (HC) Upon the arrival of a new session destined to an APSD-enabled station, xed positions in the superframe are scheduled by the HC for that station This allows the APSD station to switch from the doze state into the awake state to receive or poll the HC for its buffered traf c On the other hand, if the HC detects that the station is in the awake state outside the scheduled service periods, it can communicate with the APSD-enabled station asynchronously Since the IEEE 802.

In these networks, QoS support are provided through resource reservation mechanisms To accomplish resource reservation, the following steps are followed:.

11 standard does not provide a mechanism for placing APs into power-save mode, the only available schemes are proprietary Two such mechanisms have recently been proposed in reference 6 and 7, based on extensions to the IEEE 80211 standard In the rst scheme, the AP makes use of xed sleep and awake periods in order to perform power saving The second approach extends the rst by introducing a dynamic mechanism for updating the sizes of the sleep and awake periods In this case the AP adaptively modi es its sleep schedule to support best effort traf c The scheme is based on extensions to IEEE 80211e [8] where an AP that supports power saving includes a network allocation map (NAM) in its beacon broadcasts The NAM speci es periods of time within the superframe when it is unavailable, and during these periods the AP may conserve power.
