“…Therefore, it is necessary to optimize AODV based on metrics like, link quality, neighborhood node location, node velocity etc. [4]. To handle these challenges, signal strength based gossip flooding mechanism for AODV is proposed in this article.…”

Reactive routing protocols for MANETs have outperformed the proactive protocols as they incurred less overhead for maintaining routing information. Reactive protocols working "on demand" principle rely on the flooding of route request (RREQ) packets for route discovery. This flooding results in problems such as; "RREQ storm", energy consumption of nodes and bandwidth consumption of shared channel. Hence, usability of reactive protocols is under scanner. This paper suggests Received signal strength (RSS) based gossip flooding approach that modifies the RREQ rebroadcast mechanism of AODV. Experimental results show that RSS based gossip with probability p=0.66 reduces the RREQ rebroadcast by 15%, without adversely affecting the network performance in terms of connectivity, throughput and PDR, or end-to-end delay.

“…Hence, optimized routing approaches have been implemented on the traditional AODV protocol. These approaches have been explained in detail in [8]. These approaches help to reduce the problem of unnecessary consumption of node energy and bandwidth by modifying different aspects of the traditional AODV protocol.…”

The multi-hop ad hoc networks are self organizing networks with dynamic topology. The reactive and proactive protocols are designed to handle these dynamically changing networks. Ad Hoc On-Demand Distance Vector (AODV) Routing Protocol is one such Reactive protocol that has been widely adopted in MANETs. In this protocol, routes are maintained as and when required, i.e. they operate 'On Demand'. AODV relies on 'Hello' messages to maintain local link connectivity. The hello messages are sent periodically, the period of which is defined by 'AODV hello interval. In this paper, we investigate the performance of AODV protocol by varying the hello interval. The performance is analyzed in terms of Quality of Service parameters such as throughput, End-to-end Delay and PDR. Our experimental results show that the performance of AODV is improved when hello interval is increased.

Ad hoc On-demand Distance Vector routing protocol (AODV) is a reactive routing protocol used in MANETs that makes use of Hello Messages for local Link connectivity. Every node in a network broadcasts hello messages to all its neighbours at a default hello interval of 1 second. However, this continuous broadcast leads to unnecessary energy consumption and energy utilization. This paper suggests an Adaptive Hello messaging based approach that modifies the Hello message broadcast mechanism of AODV. This approach makes the hello interval adaptive by making it directly proportional to event interval thereby suppressing unnecessary hello messages and breakage of links to the destination without adversely affecting the network performance in terms of throughput, end-to-end delay, PDR and jitter.
