TAILIEUCHUNG - Evaluating the optimal sensor placement for smoke detection
Wireless Sensor Networks (WSNs) consist of wireless sensor nodes, where the choice of their deployment scheme depends highly on the type of sensors, their application, and the environment they will operate in. The performance of WSNs can be affected if the network is deployed under different topologies. In this paper various strategies for positioning nodes in WSNs for fire detection (grid, triangular and strip) are discussed. | Yugoslav Journal of Operations Research 26 (2016), Number 1, 33-50 DOI: EVALUATING THE OPTIMAL SENSOR PLACEMENT FOR SMOKE DETECTION Mirjana MAKSIMOVIĆ Faculty of Electrical Engineering, University of East Sarajevo, Bosnia and Herzegovina mirjana@ Vladimir MILOŠEVIĆ Faculty of Technical Sciences, University of Novi Sad, Serbia tlk_milos@ Received: March 2014 / Accepted: January 2015 Abstract: Wireless Sensor Networks (WSNs) consist of wireless sensor nodes, where the choice of their deployment scheme depends highly on the type of sensors, their application, and the environment they will operate in. The performance of WSNs can be affected if the network is deployed under different topologies. In this paper various strategies for positioning nodes in WSNs for fire detection (grid, triangular and strip) are discussed. We propose the proper placement of the smoke sensors to satisfy two important network design objectives: to maximize the network lifetime after fire ignition, and to achieve full coverage by using a minimum number of sensors (especially in a deterministic node deployment).

INTRODUCTION A Wireless Sensor Network (WSN) consists of spatially distributed autonomous sensor nodes working together for numerous sensing and monitoring services. Applications of WSN are: environmental monitoring, industrial machine monitoring, surveillance systems, military target tracking, etc. Each of the application differs in features and requirements. The application requirements vary in terms of computation, storage, and user interface. Till now, there is no single platform applicable to all applications. The development of new communication protocols, algorithms, designs, 34 , V. Milošević / Evaluating The Optimal Sensor Placement and services are needed to support diversity of applications [1].
