SARA: A Self-Adaptive Routing Algorithm in Wireless Sensor Network

Abstract

With the development of WSN applications, there is increasing concern for the research of WSN. The routing algorithm is one of the important supporting technologies of WSN. However, the current studies of routing algorithms focus on the single performance. For instance, the aim of Energy Multipath Routing Algorithm is to maximize the network life cycle. And the aim of the Minimal-hop routing algorithm is to minimize the network transmission delay. This paper synthesizes the three performance indicators, namely network life cycle, network latency and network reliability to propose a Self-adaptive Routing Algorithm (SARA). SARA could satisfy different network requirements by adjusting the parameters. The experimental result shows that SARA can reduce the network latency, extend the network lifecycle and enhance the network reliability compared with the Multi-path energy efficient algorithm.
