Ubiquitous Computing is a new Internet revolution that will allow, among other uninterrupted access to the network actors machines and some mobile devices. In this paper, the example of mobile laboratory is composed a Wireless Sensor Network (WSN) whose the data collection is done through a special node called master. HIP (Host Identity Protocol) is used as communication protocol. The HIP architecture uses the identity/locator split. In the proposed architecture, mobility is managed by three entities including mobile node (master), locator manager or fLRVS (firewall and Local Rendezvous Server), access link manager or S-RVS (Subnet Rendezvous Server). The new introduced network entity is fLRVS, it is responsible for the node accessibility in the domain and filtering based on the HI (Host Identifier). The node identifier named HI, is the public key of an asymmetric key-pair. The HIP Registration and HIP Rendezvous Extension have been modified to achieve this authentication system. A proposed mobility scheme, named HIPdisass, is based on a proactive handover mechanism which reduce latency and packet loss. At outside, remote hosts can connect to the mobile laboratory safely regardless of the type of access network.
