Abstract: Task description is the most basic component of task collaboration in Wireless Sensor Network(WSN), which refers to task description, task decomposition, task allocation, task scheduling and task execution. Recent representative task description fashions are explicitly studied in this paper. A service-oriented task description fashion is put forward towards a three-layer WSN architecture. This description supplies user with a simple, efficient description method and convenience of submitting task requests, decreases the complexity of task assignment system efficiently.

摘要： 无线传感器网络的任务协同主要指任务的描述、分解、分配、调度与执行，其中，任务描述是任务协同的基础。该文比较几种任务描述方式，针对3层的传感器网络体系结构提出一种面向服务的任务描述方式。实践表明，该描述方式提供一种简单、高效的描述手段，方便用户提交任务请求，有效地降低了任务分配系统的复杂性。
