What is adhoc routing protocol?
Ad hoc routing protocols can be broadly classified as being Proactive ( or table- driven) or Reactive (on-demand). Proactive protocols mandates that nodes in a MANET should keep track of routes to all possible destinations so that when a packet needs to be forwarded, the route is already known and can be immediately used.
What are the problems facing routing in ad hoc networks?
Problems Facing Routing in Ad hoc Networks ❒Routers are now moving ❒Link changes are happening quite often ❍Packet losses due to transmission errors ❒Event updates are sent often – a lot of control traffic ❒Routing table may not be able to, converge ❒Routing loop may exist ❒Current wired routing uses shortest path metric 1-23
What is ad hoc networking?
The term ad hoc is a Latin word that literally means "for this," implying improvised or impromptu. Ad hoc networks are mostly wireless local area networks (LANs). The devices communicate with each other directly instead of relying on a base station or access points as in wireless LANs for data transfer co-ordination.
How to handle highly dynamic nodes in an ad hoc network?
This has been shown to be a reasonable approach since dividing the nodes in an ad hoc network into clusters seems to be a promising method in taking care of highly dynamic nodes. Hybrid methods can reveal themselves to be attractive as they can provide protocols that can address further robustness and efficiency.

What are external events in ad hoc networks?
A Modular Cross-Layer Architecture for Ad Hoc Networks9 example of an external event is a condition on the host energy level. A protocol can subscribe for a “battery-low” event, specifying an energy threshold to the NeSt, which in turn will notify the protocol when the battery power falls below the given value.
