Multipath design for 6L0WPAN ad hoc on-demand distance vector routing

摘要

Wireless networks of future generation are envisioned to be a combination of diverse networks environment and access technologies that can give us convenient wireless environment. The IEEE 802.15.4 standard is a low cost, low-rate, low-power wireless personal area network technology. IP for smart objects (IPSO) seeks to extend the use of IP networking into resource-constrained devices over a low-power network. IPv6 over low-power wireless personal area network (6L0WPAN) is specified by the IETF Working Group, and advanced by the IPSO alliance. 6L0WPAN Ad Hoc on-demand distance vector routing (LOAD) is based on ad hoc on-demand distance vector (AODV), and simplifies the routing protocol for 6L0WPAN mesh network. Although the LOAD simplifies the AODV for 6L0WPAN mesh network, but the broadcasting route request (RREQ) message of route discovery is still caused whole network overhead. In this paper, we would like to use the concept of Ad Hoc on-demand multipath distance vector routing (AOMDV) for LOAD to find multipath during the route discovery. If the path fail, we still have alternate path can be used for reducing the overhead of route discovery for the network.
