[Smac-users] S-MAC and mobile Nodes

Tue Oct 19 02:02:42 PDT 2004

Hi all!

According to the publications concerning s-mac, a node which overhears 
more than one schedule may adopt both of them to improve inter-cluster 
communication. What about mobile nodes? In our project nodes will be 
mobile and will move at random through our network at speeds of up to 10 
mph since people are wearing them.

So what happens if a node leaves one cluster and joins another? Is this 
possible? Will this node keep adopting schedules until it is awake at all 
times or will he be able to drop old schedules which he no longer needs to 
adhere to?

Are there any publications which have measured performance of s-mac when 
nodes are mobile?
