I'm researcher studying platform of sensor networks.
I have some questions, and I'll appreciate your answers.
1. Mate has stacks at each three contexts and a stack is isolated for return-address and operand.
I'm wondering about reason to divide stack into return-addr and operand.
I'm guessing it is due to security/robustness. but I think it has more flexibility with one-stack than with isolated stack. for example, more calling depth with less operands, or more operands with less calling depth.
2. It seems that anybody can install new network application into sensor field. but I looks very dangerous. Is there any mechanism for security? for example, key for installation... etc.
3. I met mate virtual machine on a paper 'Mate: A Tiny Virtual Machine for Sensor Networks', and I guess that many development/research is going on about Mate. but, There are few information about Mate and It seems that TinyOS is main development stream in these days.
Let me know further works about Mate virtual machine after the paper I read and future of Mate virtual machine.
Sincerely yours. Dennis Kim.
