AODV - jyotibatra - 08-16-2017 AODV [attachment=16656] AODV Overview AODV is a packet routing protocol designed for use in mobile ad hoc networks (MANET) Intended for networks that may contain thousands of nodes One of a class of demand-driven protocols The route discovery mechanism is invoked only if a route to a destination is not known Source, destination and next hop are addressed using IP addressing Each node maintains a routing table that contains information about reaching destination nodes. Each entry is keyed to a destination node. Advantages: -control overhead will be less as compared to purely table based protocols as routes are created only on demand -routes are guaranteed to be loop-free and valid -saves storage space and energy Disadvantages: -requirement of symmetric routes -use of periodic hello messages -As traffic increases AODV has lower packet delivery fraction -Higher end-to-end delay -Increased control overhead LB-AODV(AODV WITH LOAD-BALANCING) As traffic increases, LB-AODV routing protocol has a significantly higher packet delivery fraction, a lower end-to-end delay and a reduced routing overhead when compared with AODV AODV route selection is regulated by a distributed grouping mechanism, which divides the mobile nodes logically into different groups to reduce and distribute routing traffic over the network. Load-balancing is accomplished by balancing the number of source nodes among the groups, a process that can be controlled and updated by the gateway(s). |
