Introduction • Emergency - the need for an easily deployable
infrastructure at the disaster site – mobility and heterogeneous networking support is extremely
important
• The proposed combination of PMIPv6 and Host Identity Protocol (HIP) [5] – represents a secure global and localized mobility solution– an efficient mechanism of intra and inter-technology handover

Host Identity Protocol • the IP address is– a locator used to route traffic to the destination node and – The identifier of the node
• the same node would have different identifiers depending on where it is positioned in the network
• HIP separates the identifier from the locator– the Host Identity (HI) serves as the identifier
• The public key of an asymmetric key-pair.• a 128-bit hash of the HI, called the Host Identity Tag (HIT), is used
– allows it to be used instead of an IPv6 address at higher layers
– The IP address is still used as the locator

Micro-Mobility Solutions for HIP• In [7], Novaczki et al. propose a micro-mobility scheme. – the Local Rendezvous Server (LRVS)
• acts as the Mobile Anchor Point (MAP) in HMIPv6.the high number of messages needed to update
• In [8], So and Wang propose a new HIP architecture composed of micro-HIP (mHIP) agents– The mHIP agents under the same network domain share a
common HIT– MN register itself in the RVS with the HIT of the mHIP domain
breaks the macro-mobility of HIP • as changing domain implies changing HIT

PMIPv6 and HIP-based Approach• HIT_domain - represent the whole PMIPv6 domain– a common HIT shared by all the entities in the PMIPv6 domain
(LMA and MAGs)• besides their own HIT
• A Mobility Management Key (MMK) – used by the MN to verify the signature of trusted PMIPv6’s
entities.
• PMIPv6 use a per-MN-prefix scheme and not a per-interface-prefix approach– All interfaces of the MN share a HNP

Communication Setup• Initiated by the CN– the CN get the MN’s RVS server from the DNS server– The CN starts the HIP BE with the MN via RVS– I1 is routed by LMA to the correct MAG– The rest of the BE will operate via a similar
processInspecting the HIP BE, the LMA record the mapping between
the Security Parameters Index (SPI), CN’s IP address, MN’s IP address and the serving MAG

The MN recognizes the HIT_domain and the MMK in the message and accepts the reply.

Inter-technology Handovers
1)Switch on a new wireless interface.2)The same HNP, no need to UPDATE RVS.

• Handover latency– time that elapses between the moment in which the L2
handover completes at the RAP and the moment the MN receives the first packet after moving to the new point-of-attachment
• TL2 : represents the delay due to layer 2 signaling, • TMD : the movement detection delay, • TAC : the address configuration delay• TREG : the location registration delay

comments• Contribution
– 提出讓 LMA/MAG intercept and involve in the HIP messages– 定義 interleaving messages for HIP+PMIPv6
• Deploying HIP may not be easy– requires modifications in protocol stacks and applications
• The definition of “L2 handover complete”
• Session mobility, Human mobility– 可能可以用 HI作為 session/man identifier– 同一個人用不同 node時 ,經一認證機制 ,將屬於該人的 HI assign到他用的機器上
