“…In order to deal with the problem of "broadcast storm" in multi-hop ad hoc networks, various optimized flooding mechanisms are proposed [4][5][6][7][8][9][10][11]. These schemes advocate controlling the RREQ broadcasts adopting probabilistic approach, in which intermediate nodes forward the RREQs with lower probability based on some control metric such as node density, distance, number of neighbors covered, speed, etc.…”

“…However, the optimization approaches [5][6][7][8][9][10] are computationally intense and thus difficult to implement. Hence authors adopted a simple mechanism named 'Channel Quality based Adaptive Gossip Flooding mechanism for AODV (CQAG-AODV)' and presented performance improvement through the reduction in link failures [11]. By accounting signal quality in the routing process, CQAG-AODV tuned the rate of RREQ broadcasts and controlled the number of RREQs forwarded, as well as discovered good quality routes that are robust to failures.…”

“…Although, these approaches utilize the same metric of signal quality at the physical layer as suggested in [11], the proposed CQAG-AODV did not constitute interference in the routing decision. This is so because, in multi-hop wireless networks interference is less critical than connectivity [17][18]; interference mainly impacts the network capacity and not the connectivity.…”

To address the “broadcast storm” problem associated with flooding-based route discovery mechanism of reactive routing protocols, probabilistic approaches are suggested in the literature. In the earlier work, Gossip flooding mechanism of Haas et.al. was extended with signal quality, to propose channel quality based adaptive gossip flooding mechanism for AODV (CQAG-AODV). Following the cross-layer design principle, CQAG-AODV algorithm tried to discover robust routes, as well as address the “broadcast storm” problem by controlling the rebroadcast probability of Route request (RREQ) packets on the basis of signal strength experienced at the physical layer. This paper investigates the connectivity of CQAG-AODV through theoretical and simulation analysis. Results show that, by accounting the signal strength in the route discovery process, not only does the proposed algorithm floods a lesser number of route requests and controls the broadcast storm, but also maintains a higher level of connectivity to offer high packet delivery ratio; independent of network density and node mobility. Moreover, due to controlled routing overhead and robust route discovery, channel quality based adaptive flooding mechanism offers fringe benefit of energy efficiency as well. CQAG-AODV thus proves its suitability in a variety of use cases of multi-hop ad hoc networks including WSNs and VANETs.

This thesis addresses the problem of disseminating broadcast packets in a multi-hop wireless ad hoc network. Specifically, it focuses on broadcasting protocols in which nodes make probabilistic decisions to forward packets. In connected multi-hop ad hoc networks, this type of protocol produces a broadcasting process that saves energy and bandwidth while offering a natural rotation of the subset of forwarders over time, yet it entails minimum overhead.
