摘要

无线传感器网络的通信链路需要通过可靠传输机制来满足应用需求。在指出传统的MAC层协议无法提供能量高效的可靠传输后

提出了一种以效率为中心的可靠通信机制——分组确认机制。围绕着通信链路的EPB这一指标

采用数学手段对所提出的机制与传统的机制进行性能比较

从理论上证明了该机制的节能效果

并且该机制通过串音技术减少了传感器节点的缓存需求。最后在Micaz节点上测试了分组确认机制的性能

结果表明该机制更适合于资源受限的传感器网络的应用。

Abstract

Reliable transfer mechanism was needed for wireless sensor network’s communication link to ensure end-to-end reliability. After pointing out that traditional MAC protocol can not provide energy efficient reliable transfer

a new group-based acknowledgement mechanism

which was efficiency centric

was brought forward. And then surround- ing the EPB of communication link

mathematic method was adopted to compare the performance between the new and traditional mechanisms. And the theory analysis proves that the new mechanism can reduce energy cost obviously. Meanwhile

the new mechanism requires a smaller buffer for sensor nodes through overhearing technique. Finally

per- formance of the group-based acknowledgement mechanism has been tested through experiment on Micaz platform

which proves that this mechanism is more suitable for the application of resource limited sensor networks.
