| 摘 要： | 提出一种适用于无线传感器网络协作的扩展合同网协议.该协议在传统合同网协议中引入了信任度、阈值和优先级等策略,减少了无线传感器网络的通信开销,有效均衡了节点的能量消耗.为确保扩展合同网协议的完整性、正确性和可靠性.利用面向对象Petri网对其进行建模、分析和验证.仿真结果表明,扩展合同网协议有效地延长了网络生命周期,提高了网络的能耗效率,网络完成任务数也有了显著的增加.

| Abstract: | A collaboration approach based on an extended contract net protocol for wireless sensor networks(WSN) is presented,in which the trust degree,threshold,and priority are introduced into the classical contract net protocol.The extended contract net protocol reduces the communications consumption and balances the energy load among all nodes.To assure the correctness,completeness and reliability of the extended contract net protocol,object-oriented petri nets are employed to model it.Moreover,the characteristics... |
