Abstract:

In wireless sensor networks with mobile nodes, it is important to enhance energy efficiency. For these networks, several routing protocols have been presented to reduce packet loss and increase energy efficiency. However, since these protocols cannot create appropriate clusters, they are not extremely energy efficient. In this letter, a centralized energy-efficient clustering routing protocol for mobile nodes (CEECR) is developed to minimize energy dissipation and maximize packet delivery ratio. In our protocol, a centralized cluster formation algorithm is presented to produce optimal clusters by utilizing node mobility and the node energy property. Furthermore, a detached node selects its optimal cluster head according to the node distance property, node mobility, and the node energy property. The performance of CEECR is then compared to clustering-based protocols, such as LEACH, LEACH-C, LEACH-Mobile, CBR, MBC, and LEACH-MF. Simulation results show that CEECR reduces average energy dissipation and improves packet delivery ratio over its comparatives.

I. Introduction

With deeply development of wireless sensor networks (WSNs) in recent years, a variety of types of WSNs has emerged, comprising terrestrial WSN, underground WSN, underwater WSN, multi-media WSN, and mobile WSN [1]. An important challenge of mobile WSNs is energy efficiency as well as reducing packet loss. This necessitates designing novel energy-efficient solutions, among which hierarchical (clustering) routing protocols can aid in minimizing energy consumption while supporting mobility for mobile WSNs [2].
