摘　　要：以无线传感器网络单目标追踪为背景,提出了一种基于仲裁的动态联盟协同任务分配机制,简化了现有动态联盟的形成机制,提高了动态联盟的结盟成功率,并加入了盟员更新机制,实现了动态任务分配,从而在降低能量消耗的同时提高了网络性能.在仿真中,将基于仲裁的动态联盟协同任务分配机制与现有的基于案例推理的动态联盟机制进行比较,验证了基于仲裁的动态联盟机制在能耗和追踪性能方面的优势.*A mediation-based dynamic coalition task allocation scheme for single target tracking in wireless sensor networks is presented, which simplifies the negotiating process of coalition in the present scheme. Success ratio of the coalition formation is increased. A coalition member updating scheme is introduced to realize dynamic task allocation. The energy consumption is reduced and the performance of the network is improved as well. The mediationbased dynamic coalition task allocation scheme is compared with the case-based reasoning one in simulations, and the result demonstrates that the former one is advantageous in energy consumptions and tracking qualitv.
