دانلود مقاله Multiple Receiver Strategies for Minimizing Packet Loss in Dense Sensor Networks

Bernhard Firner, Chenren Xu, Richard Howard, and Yanyong Zhang ABSTRACTA typical wireless sensor network consists of many small sensorsthat collect instrument data around their locations andforward it to a central location for data processing. Thesenetworks can be deployed to monitor livestock and agriculturalassets, products in a store, patients in a hospital, andso on. In many cases sensors have to be densely deployed,and collisions or overhead due to collision avoidance willconsiderably degra ...
