Post-Deployment Energy-Efficient Schemes in Wireless Sensor Networks

Abstract

Once wireless sensor networks are deployed, they are expected to work autonomously for a long time. However, the limited energy of sensor nodes is the main constraint in achieving it. Therefore, to increase the overall lifetime of sensor networks, the sensors must use their limited energy source in an energy-efficient manner. In wireless sensor networks, logical topologies play a significant role in ensuring various constraints such as effective use of limited resources, bandwidth utilization, latency, and quality of communication. In this chapter, the authors discuss three famous energy-efficient topologies of sensor networks that minimize the overall energy consumption during the communication process. These topologies are cluster, chain, and tree-based. The authors highlight the design issues of each topology and discuss the benefits of each topology over other topology. The focus of the chapter will be more on cluster-based rather than chain and tree as it is widely used compared to the chain and tree-based topologies for energy-efficient communication.
