SELF ORGANIZING SENSOR NETWORK: DEPLOYMENT AND RELOCATION

Abstract

Sensor networks have been identified as one of the most important technologies of the 21st century. Advances in micro-electro-mechanical systems (MEMS), electronics and wireless communications have enabled the development of low-cost, low-power, multifunctional sensor nodes that are small in size and have capabilities of sensing, data processing, communication, storage etc. A sensor network is composed of a large number of such nodes densely deployed in a region to monitor a particular phenomenon. Sensor network is a fresh research area with applications in military, environment monitoring, disaster management etc. Sensors are used to measure and/or monitor parameters that may vary with place and time which prompts the need for the Dynamic Sensor Network (DSN). Self- Organized Sensor Network (SOSN) is a kind of DSN, which can achieve the necessary organizational structures without requiring human intervention in order to sense the time varying spatial signal efficiently.
