Impact of mobility models on clustering based routing protocols in mobile WSNs

TL;DR

This study compares hierarchical routing protocols in mobile wireless sensor networks under various mobility models, highlighting the significant impact of mobility on protocol performance and the advantages of position-based routing.

Contribution

It provides a comparative analysis of multiple mobility models' effects on hierarchical routing protocols, addressing a gap in prior static or single-model studies.

Findings

Mobility significantly affects routing protocol behavior.

Position-based protocols outperform non-position-based ones.

Multiple mobility models are essential for accurate protocol evaluation.

Abstract

This paper presents comparison of different hierarchical (position and non-position based) protocols with respect to different mobility models. Previous work mainly focuses on static networks or at most a single mobility model. Using only one mobility model may not predict the behavior of routing protocol accurately. Simulation results show that mobility has large impact on the behavior of WSN routing protocols. Also, position based routing protocols performs better in terms of packet delivery compared to non position based routing protocols.
