Barrier Coverage In Wireless Sensor Networks, Zhibo Wang

Doctoral Dissertations

Barrier coverage is a critical issue in wireless sensor networks (WSNs) for security applications, which aims to detect intruders attempting to penetrate protected areas. However, it is difficult to achieve desired barrier coverage after initial random deployment of sensors because their locations cannot be controlled or predicted. In this dissertation, we explore how to leverage the mobility capacity of mobile sensors to improve the quality of barrier coverage.

We first study the 1-barrier coverage formation problem in heterogeneous sensor networks and explore how to efficiently use different types of mobile sensors to form a barrier with pre-deployed different types of …

Wsnfs: A Distributed Data Sharing System For In-Network Processing, Joshua C. Kiepert

Boise State University Theses and Dissertations

Wireless sensor networks (WSNs) have emerged as versatile platforms for a wide range of scientific data acquisition applications. Wireless sensor network systems are used in many applications including: surveillance, environmental monitoring, target tracking, wildlife tracking, personal health monitoring, machinery monitoring, and many others. Current research efforts in WSN system designs are moving toward approaches that enable direct in-network processing of acquired sensor data to avoid the high energy costs associated with the bulk transmission of data to outside systems for processing. Implementation of collaborative in-network processing algorithms is a non-trivial issue for WSN system development. Design complexity for in-network processing …
