DSES-DC: A Dijkstra scheme for environmental sensory data communication in stationary energy-constrained sensor networks

Recent technological advances have made it practicable for wireless sensor network (WSN) deployments in various environmental events monitoring applications. The wireless nodes of WSNs are often powered by restricted-battery resources that are tough to replenish after deploying the nodes in the environmental monitoring field. As a result, environmental WSNs are energy-restrained and predisposed to early-failure while projected to function for long-term without battery-backups. Therefore, the design of more efficient schemes to improve the lifetime and communication performances in environmental WSNs is crucial. This work presents a Dijkstra scheme for environmental sensory data communication (DSES-DC) that combines the full advantage of an adapted Dijkstra shortest algorithm with event-based communication-model (ECM). The proposed DSES-DC focuses on enhancing both sensor lifetime and delay performances in various environmental WSN monitoring operations. Performance analysis with ns-3 network simulator attests that DSES-DC outperforms HEED and KDUCR in terms of network latency and network lifetime under stationary deployment conditions..
