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
