A Novel Real-Time Routing Protocol for Wireless Sensor Networks
Liming He · 2009
In recent years, many routing protocols for wireless sensor networks (WSNs) have been designed to achieve high energy-efficiency, high reliability, low overhead, etc. However, few routing protocols for WSNs were designed to minimize the communication delay, which is one of the most important requirements for applications of WSNs, such as real-time surveillance systems. In this paper, a novel real-time routing protocol for WSNs is proposed for guaranteeing real-time communication. Additionally, energy-efficiency that prolongs the network lifetime is fully considered. Performance analyses and simulation results show that our protocol has much better performance than Directed Diffusion and Rumor Routing in terms of both communication delay and network lifetime.
