Event Localization in Wireless Sensor Network using Binary Sensors

Sensor networks are gaining importance as they have vast potential for diverse application areas like monitoring, localizing and tracking of environmental phenomenon. The sensors are constrained by extremely scarce resources, unreliable communication link and faulty nodes. There is a need to address these harsh operating conditions. Real time sensitive applications which require fault free observations from sensor nodes is another challenging task in wireless sensor network scenario. Binary wireless sensor network is an extension of wireless sensor network where sensors give binary outputs. This paper focuses on the suitability of binary sensors for event localization purpose. In the sequel, this paper presents application of binary sensors for event localization in wireless sensor network. Comprehensive literature survey on event localization in context of wireless sensor network is presented and discussed. Evaluation of related work is also presented in order to understand gap analysis. The mathematical model of binary sensor operation and the pseudo code for wireless sensor network functioning with and without faulty binary sensor node is presented and discussed. Finally paper concludes with an use case explaining event localization in wireless sensor network using binary sensors. Keywords—Binary wireless sensor network, Region of Coverage
