Energy-Efficient Multi-Path Routing with Short Latency and Low Overhead for Wireless Sensor Networks

In wireless sensor networks (WSNs), multi-path routing can find multiple paths from source node to sink node for achieving high reliability and high energy-efficiency. However, the existing multi-path routing protocols in the literature construct multiple paths with long latency and high overhead. In this paper, a novel multi-path routing protocol for WSNs is proposed, which can discover multiple paths with short latency and low overhead. Additionally, its energy efficiency is higher than that of the existing ones. Performance analyses and simulation results show that our proposed protocol has much better performance than the existing ones in terms of latency, overhead and network lifetime.
