A deployment procedure for wireless sensor networksAbstractSince the wireless signal is invisible and unpredictable, the deployment issue fora wireless sensor network (WSN) becomes a critical task. In this paper, a procedureof deployment for a wireless sensor network in an indoor environment is proposed. The objective of the procedure is to provide a solution guide for people who don’thave sufficient wireless communication knowledge and experience in how to correctlyplace the wireless sensor nodes or devices in the interesting indoor environment, especially in a large-scale deployment case, and then the desired communicationperformance of the wireless sensor network can be achieved. The addresseddeployment procedure is divided into four sub-procedures and is discussed in detail inthe following. A deployment plan for an office and the real deployment testing resultsare then proposed to demonstrate the efficiency of the proposed deploymentprocedure.1. IntroductionIn recent years, based on the maturity of low-power, low-cost and small-scalecircuit design technology, a newly application area of wireless sensor networks formonitoring and sensing environment, detecting the events, tracking targets in thegiven regions and providing personal network services, is arisen very quickly. Most ofthe services in this newly application area need certain infrastructure to achieve thedata sensing, processing and communication tasks. That is why the deploymentprocedure is regarded as the most important issue in wireless sensor network .Since our use of wireless sensor networks lies on indoor applications, we considerthat a reliable communication channel should be constructed before anyapplication-oriented devices being put into action. When it comes to sensor networkdeployment, we put our attention on deploying the communication backbone ofsensor network while fulfilling the connection quality and coverage constraints intotarget area. Furthermore, the deployment planning in the propos
