An enhanced routing mechanism based on ZRP in ad hoc networks

Ad hoc networks are of great use from military applications to emergency management, providing the aid to deal with affairs that happen in hostile environment. ZRP is a hybrid routing protocol used in ad hoc networks, which proactively keeps routing information within the routing zone and reactively bordercasting query and message packets to external zones, so that routing in ad hoc networks will be more efficient. However, the cost in delays and overhead is also a big obstacle in improving the performance of ZRP. Thus, in this paper, we introduce a new mechanism of routing mechanism. This mechanism selects key nodes in routing to find destination node. With modelling and simulation, we have proved that the enhanced routing mechanism we propose is convincing.
