An Energy-Efficient Sensor Protocol for Information via Negotiation

Abstract

As a product of the combination of computing, communication and sensor technologies, wireless sensor networks become an hot research branch at the area of wireless communications. In wireless sensor networks, energy efficiency is the most important factors affecting performance of sensor networks. Excellent routing algorithms could significantly increase the utilization of energy and prolong service life of sensor network. Since data-centric routing algorithms are easy to deploy and have stronger robustness in applications [1], many new protocols are developed on the basis of it. This article analyzes some commonly used symbolic algorithms, describes their advantages and disadvantages, and improves on the basis of the SPIN protocol to improve the energy efficiency and extend the network lifetime.
