This project, establishing a wireless and sensor networking laboratory, supports the following research projects: Area Coverage in Wireless Ad-Hoc Sensor Networks, Efficient Broadcasting in Wireless Ad-Hoc Sensor Networks, and Topology control in Mobile Ad-Hoc Networks with Hitch-Hiking.In the 1st project, an energy-efficient localized and distributed area coverage protocol will be designed that provides sensor network connectivity and a reliable retrieval mechanism. The performance of the protocol will be analyzed for a sensor network through simulation using the Opnet network simulator, and the protocol will be implemented and tested on the MICA mote sensor platform. This area coverage problem has applications in disaster recovery, environmental monitoring, and homeland defense. In the 2nd project, efficient broadcast protocols that fit the wireless sensor network characteristics will be designed, these protocols will be simulated for large networks using Opnet and implemented and tested on the MICS mote sensor platform. Broadcast, an important operation in wireless ad-hoc sensor networks, is often encountered, for example, in data diffusion and on-demand gathering. Because of transmission redundancy, a factor that increases heavily contentions and collisions, broadcast by flooding does not constitute a feasible solution. Thus, the forwarding node needs to be selected carefully, considering the basic characteristics of a wireless sensor network, such as lack of global sensor information and resource limitation. In the 3rd project, an efficient topology control protocol will be designed, simulated in large networks using Opnet, and implemented and tested in the lab, for a mobile ad-hoc network of laptop and palm computers. Moreover, a distributed topology control mechanism will be designed that assigns a transmission power to every wireless node such that the resulting topology is strongly connected and the total energy consumed is minimized. This last project addresses topology control in mobile ad-hoc networks needed, for example, in proactive routing protocols. A new energy-efficient mechanism proposed, the Hitch-hiking model, addresses this topology control problem. Exploring the advantage offered by this model, successfully decoding a packet by combining partial receptions, the investigators will strive to minimize the total power expenditure. Broader Impact: This infrastructure provides a research facility in a minority serving institution for students to conduct research in wireless and sensor networking areas. The lab impacts the education mission, including course work, and student projects. Thus, new educational opportunities will open providing better training and motivation. Results will be disseminated via web pages, invited talks, conference, presentations and journal publications.

该项目建立无线和传感器网络实验室，支持以下研究项目：无线自组传感器网络中的区域覆盖、无线自组传感器网络中的高效广播以及移动自组网络中搭便车的拓扑控制在第一个项目中，将设计一种节能的局部和分布式区域覆盖协议，提供传感器网络连接和可靠的检索机制。使用Opnet网络模拟器对传感器网络进行仿真分析该协议的性能，并在MICA微尘传感器平台上实现和测试该协议。该区域覆盖问题可应用于灾难恢复、环境监测和国土防御。在第二个项目中，将设计适合无线传感器网络特性的高效广播协议，这些协议将使用Opnet针对大型网络进行模拟，并在MICS微粒传感器平台上实施和测试。广播是无线自组织传感器网络中的一项重要操作，经常在数据传播和按需收集等过程中遇到。由于传输冗余这一严重增加竞争和冲突的因素，通过洪泛广播并不构成可行的解决方案。因此，需要仔细选择转发节点，考虑无线传感器网络的基本特征，例如缺乏全局传感器信息和资源限制。在第三个项目中，将设计一种高效的拓扑控制协议，使用 Opnet 在大型网络中进行模拟，并在实验室中针对笔记本电脑和掌上电脑的移动自组织网络进行实施和测试。此外，将设计一种分布式拓扑控制机制，为每个无线节点分配传输功率，使得所得拓扑强连接并且消耗的总能量最小化。最后一个项目解决了移动自组织网络中所需的拓扑控制问题，例如主动路由协议中的拓扑控制。提出的一种新的节能机制，即搭便车模型，解决了这个拓扑控制问题。探索该模型提供的优势，通过组合部分接收成功解码数据包，研究人员将努力最小化总功率消耗。更广泛的影响：该基础设施为少数族裔服务机构提供了一个研究设施，供学生在无线和传感器网络领域进行研究。实验室影响教育使命，包括课程作业和学生项目。因此，新的教育机会将开放，提供更好的培训和动力。结果将通过网页、受邀演讲、会议、演讲和期刊出版物传播。
