一种针对无线传感器网络的移动代理结构(英文)

A Mobile Agent Architecture for Wireless Sensor Networks

在传统的用户/服务器网络结构中,本地数据需要传送到目的地去进行计算和处理,而移动代理的出现则使移动计算变为了现实.移动代理的移动性使之比用户/服务器网络结构更适用于传感器网络.本文提出了一种适用于传感器网络的通用移动代理结构.这种结构称为基于移动代理的传感器网络(MAWSN).本结构中的移动代理可以从以下三个方面减少信息冗余度和通信的额外开销以延长网络的生存时间:①通过本地处理功能减少应用层的冗余度;②通过数据汇聚功能减少数据的空间冗余度;③通过多目标数据融合功能减少通信的额外开销.

In contrast to the traditional client/server based network computing, where local data are transferred to destination directly, mobile agent leads to a new computing paradigm, namely, mobile - agent based computing. The advantages of the mobile agent paradigm make it more suitable for wireless sensor networks （WSNs） than client/server paradigm. This paper proposes universal mo- bile agent architecture for WSNs. The proposed architecture is called MAWSN （mobile agent based wireless sensor network）, where mobile agent is dedicated to eliminate information redundancy and communication overhead in order to prolong network lifetime from following three aspects： ① application redundancy eliminating by mobile agent assisted local processing; ② spatial redtmdancy eliminating by mobile agent assisted data aggregation; ③ communication overhead saving by mobile agent assisted multiple targets＇ data combining.
