Data diffusion considering target mobility in large-scale wireless sensor network

Abstract

In this paper, we propose DDTM, Data Diffusion considering Target Mobility for large-scale WSN. Most of existing routing protocols did not consider mobile target and sink. So it requires frequently flooding and path update whenever targets or sinks move. This can lead to drain battery of sensors excessively and decrease lifetime of WSN. We proposed DDTM for Target Mobility. DDTM decreases a consumption of energy as reusing the existing grid structure of existing routing protocol TTDD, when the target moves in local cell. We evaluate performance of DDTM and TTDD in target mobility and scalability through measuring the mathematical cost. Our results show that DDTM supports target mobility efficiently in WSN. © 2008 Springer Berlin Heidelberg.
