A multiple care of addresses model

Resilience, load balancing and ubiquitous support can be improved by multihoming configurations that explore the plurality of wireless technologies available nowadays. Nevertheless, efficient multihoming configurations require support from all layers, as for instance in, network protocols which must incorporate mechanisms to support multiple addresses. Multiple Care of Addresses Registration (MCoA) is a protocol that extends Mobile IPv6 to enable the registration of multiple addresses. This paper presents mCoA++, our publicly available simulation model for OMNeT++ which implements the Multiple Care of Addresses Registration protocol recently standardized by IETF. Filling a gap in the MCoA specification, mCoA++ incorporates cross-layer mechanisms that tailor address selection according to application requirements. We evaluate our mCoA++ implementation and compare simulation code performance with xMIPv6. We find that mCoA++ adds multiple care of address support in OMNeT++ without introducing any significant overhead.
