MillibotsMillibots Modularity - modularity in sensing, processing and mobility allows dynamic
configuration based on task
Localization - The team needs to be able to track its position even in the presence oferrors
Team Architecture - An architecture is needed to coordinate movement and collectsensor information
Self Repair - The team can detect failures and fix themselves in the field

WSNsWSNs vs. MANETsvs. MANETs
The number of sensors can be several ordersof magnitude higher than the nodes in an ad-hoc network
Sensor nodes are densely deployed
Sensor nodes areprone to failure
The topology of a sensor networkchangesvery frequently
Sensor nodes are limited in power,computational capabilities, andmemory
