An improved routing protocol for power-line network based on AODV

According to the topological feature of the power-line network, an improved On Demand Distance Vector (IPODV) routing is proposed to ensure an efficient data transmission. It is based on Ad hoc On-Demand Distance Vector (AODV) Routing which is a powerful routing protocol used in ad-hoc networks to deal with the fast changing logical topology. IPODV improves two modules of conventional AODV: neighbor table management and route maintenance mechanism. The improved neighbor table management is applied to select stable neighbors to participate in the route discovery. Meanwhile, the route maintenance mechanism is improved to reduce the routing maintenance overhead. It is shown by simulations and experiments that IPODV reduces the routing overhead and improves the stability of the routes compared to conventional AODV.
