Abstract

In this work, we consider the problem of reliable data dissemination in mobile wireless sensor networks. We propose a Localized Gradient Management Algorithm (LGMA) that operates as a mobility sub-module for data-centric protocols. LGMA allows sensor nodes more responsibility in keeping the gradients in their neighborhood operational by using local information deduced from their environment. Performance comparisons of LGMA versus a Sink-Oriented data dissemination protocol with location updates show that LGMA provides considerably higher event delivery ratio under multiple scenarios and rates of sink and network mobility while incurring much lower communication overhead and enabling faster gradient repairs.
