Performance analysis of opportunistic broadcast for delay-tolerant wireless sensor networks
, Article Journal of Systems and Software ; Vol. 83, issue. 8 , 2010 , p. 1310-1317 ; ISSN: 1641212 ; Sarbazi-Azad, H ; Karlsson, G ; Sharif University of Technology
Abstract
This paper investigates a class of mobile wireless sensor networks that are unconnected most of the times; we refer to them as delay-tolerant wireless sensor networks (DTWSN). These networks inherit their characteristics from both delay tolerant networks (DTN) and traditional wireless sensor networks. After introducing DTWSNs, three main problems in the design space of these networks are discussed: routing, data gathering, and neighbor discovery. A general protocol is proposed for DTWSNs based on opportunistic broadcasting in delay-tolerant networks with radio device on-off periods. Three performance measures are defined in the study: the energy for sending queries to ask for data from...
