LATONA: an advanced server architecture for ubiquitous sensor network

The emerging Ubiquitous Sensor Network (USN) makes connection less datagrams and short event packets get popular. A large number of short term event packets of USN can cause serious problems, such as interrupt handling overhead and context switching overhead. Furthermore, heavy load of the packet security methods needs enough processing power. Then, the more USN develops, the more network overheads would be loaded into host CPU. To solve the problems, we propose a special server component including TOE (TCP/IP Offloading Engine) and H/W IPSec (IP Layer Security) for USN.
