Extending the lifetime of wireless sensor network with partial SDN deployment

Abstract

-Energy efficiency is one of the key requirements in Wireless Sensor Networks (WSNs). In order to optimize energy usage at sensor nodes, this paper proposes a new network architecture that relies on concepts of Software Defined Networking (SDN). Since SDN is a relatively new technology, originally envisioned for wired networks, it cannot be expected to get immediately and completely adopted in WSN domain, regardless of potential benefits. For this reason, we consider incremental SDN deployment where SDN nodes coexist with traditional sensor nodes, and propose a new routing algorithm for SDN controller that prolongs the WSN lifetime even when a small percentage of SDN nodes is deployed.

Roteamento para Estender o Tempo de Vida de Redes de Sensores através de SDN e Caminhos Disjuntos

“…No trabalho realizado em [10], os autores consideram uma implementação mista em que nodos chamados de (SDNSN), habilitados a integrar uma RSSF baseada no conceito de SDN, coexistem com nodos que integram RSSFs tradicionais. Como resultado, os autores pretendem verificar se é possível melhorar o controle de tráfego e estender a tempo de vida de uma RSSF, considerando que nem todos os nodos podem ser controlados pelo controlador SDN.…”

A Mechanism for Load Balancing Routing and Virtualization Based on SDWSN for IoT Applications

“…Given enormous data and energy constraints in WSNs, a solution should be proposed to balance the network energy consumption and prolong the network lifetime. Routing is an option for energy consumption reduction [13]. The network energy consumption can be balanced via correct routing.…”
