Ad hoc On-Demand Distance Vector Routing
 | This article's lead section may be too short to adequately summarize the key points. (December 2013) |
Ad hoc On-Demand Distance Vector (AODV) Routing is a routing protocol for mobile ad hoc networks (MANETs) and other wireless ad hoc networks. It was jointly developed on July 2003 in Nokia Research Center, University of California, Santa Barbara and University of Cincinnati by C. Perkins, E. Belding-Royer and S. Das.[1]
AODV is the routing protocol used in ZigBee.
Advantages and disadvantages
The main advantage of this protocol is having routes established on demand and that destination sequence numbers are applied to find the latest route to the destination. The connection setup delay is lower. One disadvantage of this protocol is that intermediate nodes can lead to inconsistent routes if the source sequence number is very old and the intermediate nodes have a higher but not the latest destination sequence number, thereby having stale entries. Also, multiple RouteReply packets in response to a single RouteRequest packet can lead to heavy control overhead.
Another disadvantage of AODV is unnecessary bandwidth consumption due to periodic beaconing. [citation needed]
