TEXT 2 1.Even though they possess much more computing, bandwidth, and energy resources than mote-class sensors, mobile devices nevertheless face resource limitations. 2.Resource constraints in traditional sensor networks have been well studied. 3.However, MCS applications introduce new aspects in this regard. 4.First, the set of devices that are collecting sensor data are highly dynamic in availability and capabilities. 5.Due to this highly dynamic nature, modeling and predicting the energy, bandwidth requirements to accomplish a particular task is harder than traditional sensor networks. 6.Second, when there are a large number of available devices with diverse sensing capabilities, identifying and scheduling sensing and communication tasks among them under resource constraints is more complex.
